## Getting Started
|
||||
|
||||
- Fork the repository on GitHub
|
||||
- Play with the project, submit bugs, submit pull requests!
|
||||
- Read the [README](README.md) for build and test instructions
|
||||
- Play with the project, submit bugs, submit patches!
|
||||
|
||||
## Contribution Flow
|
||||
|
||||
## Building
|
||||
This is a rough outline of what a contributor's workflow looks like:
|
||||
|
||||
Each plugin is compiled simply with `go build`. Two scripts, `build_linux.sh` and `build_windows.sh`,
|
||||
are supplied which will build all the plugins for their respective OS.
|
||||
|
||||
## Contribution workflow
|
||||
|
||||
This is a rough outline of how to prepare a contribution:
|
||||
|
||||
- Create a topic branch from where you want to base your work (usually branched from master).
|
||||
- Create a topic branch from where you want to base your work (usually master).
|
||||
- Make commits of logical units.
|
||||
- Make sure your commit messages are in the proper format (see below).
|
||||
- Push your changes to a topic branch in your fork of the repository.
|
||||
- If you changed code:
|
||||
- add automated tests to cover your changes, using the [Ginkgo](http://onsi.github.io/ginkgo/) & [Gomega](http://onsi.github.io/gomega/) style
|
||||
- if the package did not previously have any test coverage, add it to the list
|
||||
of `TESTABLE` packages in the `test.sh` script.
|
||||
- run the full test script and ensure it passes
|
||||
- Make sure any new code files have a license header (this is now enforced by automated tests)
|
||||
- Make sure the tests pass, and add any new tests as appropriate.
|
||||
- Submit a pull request to the original repository.
|
||||
|
||||
## How to run the test suite
|
||||
We generally require test coverage of any new features or bug fixes.
|
||||
|
||||
Here's how you can run the test suite on any system (even Mac or Windows) using
|
||||
[Vagrant](https://www.vagrantup.com/) and a hypervisor of your choice:
|
||||
|
||||
First, ensure that you have the [CNI repo](https://github.com/containernetworking/cni) and this repo (plugins) cloned side-by-side:
|
||||
```bash
|
||||
cd ~/workspace
|
||||
git clone https://github.com/containernetworking/cni
|
||||
git clone https://github.com/containernetworking/plugins
|
||||
```
|
||||
|
||||
Next, boot the virtual machine and SSH in to run the tests:
|
||||
|
||||
```bash
|
||||
cd ~/workspace/plugins
|
||||
vagrant up
|
||||
vagrant ssh
|
||||
# you're now in a shell in a virtual machine
|
||||
sudo su
|
||||
go get github.com/onsi/ginkgo/ginkgo
|
||||
go install github.com/containernetworking/cni/cnitool
|
||||
cd /go/src/github.com/containernetworking/plugins
|
||||
|
||||
# to run the full test suite
|
||||
./test_linux.sh
|
||||
|
||||
# to focus on a particular test suite
|
||||
cd plugins/main/loopback
|
||||
go test
|
||||
```
|
||||
|
||||
# Acceptance policy
|
||||
|
||||
These things will make a PR more likely to be accepted:
|
||||
|
||||
* a well-described requirement
|
||||
* tests for new code
|
||||
* tests for old code!
|
||||
* new code and tests follow the conventions in old code and tests
|
||||
* a good commit message (see below)
|
||||
|
||||
In general, we will merge a PR once two maintainers have endorsed it.
|
||||
Trivial changes (e.g., corrections to spelling) may get waved through.
|
||||
For substantial changes, more people may become involved, and you might get asked to resubmit the PR or divide the changes into more than one PR.
|
||||
Thanks for your contributions!

## 3rd party plugins
|
||||
So you've built a CNI plugin. Where should it live?
|
||||
|
||||
Short answer: We'd be happy to link to it from our [list of 3rd party plugins](README.md#3rd-party-plugins).
|
||||
But we'd rather you kept the code in your own repo.
|
||||
|
||||
Long answer: An advantage of the CNI model is that independent plugins can be
|
||||
built, distributed and used without any code changes to this repository. While
|
||||
some widely used plugins (and a few less-popular legacy ones) live in this repo,
|
||||
we're reluctant to add more.
|
||||
|
||||
If you have a good reason why the CNI maintainers should take custody of your
|
||||
plugin, please open an issue or PR.

# bridge plugin
|
||||
|
||||
## Overview
|
||||
|
||||
With bridge plugin, all containers (on the same host) are plugged into a bridge (virtual switch) that resides in the host network namespace.
|
||||
The containers receive one end of the veth pair with the other end connected to the bridge.
|
||||
An IP address is only assigned to one end of the veth pair -- one residing in the container.
|
||||
The bridge itself can also be assigned an IP address, turning it into a gateway for the containers.
|
||||
Alternatively, the bridge can function purely in L2 mode and would need to be bridged to the host network interface (if other than container-to-container communication on the same host is desired).
|
||||
|
||||
The network configuration specifies the name of the bridge to be used.
|
||||
If the bridge is missing, the plugin will create one on first use and, if gateway mode is used, assign it an IP that was returned by IPAM plugin via the gateway field.
|
||||
|
||||
## Example configuration
|
||||
```
|
||||
{
|
||||
"name": "mynet",
|
||||
"type": "bridge",
|
||||
"bridge": "mynet0",
|
||||
"isGateway": true,
|
||||
"ipMasq": true,
|
||||
"ipam": {
|
||||
"type": "host-local",
|
||||
"subnet": "10.10.0.0/16"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Network configuration reference
|
||||
|
||||
* `name` (string, required): the name of the network.
|
||||
* `type` (string, required): "bridge".
|
||||
* `bridge` (string, optional): name of the bridge to use/create. Defaults to "cni0".
|
||||
* `isGateway` (boolean, optional): assign an IP address to the bridge. Defaults to false.
|
||||
* `ipMasq` (boolean, optional): set up IP Masquerade on the host for traffic originating from this network and destined outside of it. Defaults to false.
|
||||
* `mtu` (integer, optional): explicitly set MTU to the specified value. Defaults to the value chosen by the kernel.
|
||||
* `ipam` (dictionary, required): IPAM configuration to be used for this network.

# dhcp plugin
|
||||
|
||||
## Overview
|
||||
|
||||
With dhcp plugin the containers can get an IP allocated by a DHCP server already running on your network.
|
||||
This can be especially useful with plugin types such as [macvlan](https://github.com/appc/cni/blob/master/Documentation/macvlan.md).
|
||||
Because a DHCP lease must be periodically renewed for the duration of container lifetime, a separate daemon is required to be running.
|
||||
The same plugin binary can also be run in the daemon mode.
|
||||
|
||||
## Operation
|
||||
To use the dhcp IPAM plugin, first launch the dhcp daemon:
|
||||
|
||||
```
|
||||
# Make sure the unix socket has been removed
|
||||
$ rm -f /run/cni/dhcp.sock
|
||||
$ ./dhcp daemon
|
||||
```
|
||||
|
||||
Alternatively, you can use systemd socket activation protocol.
|
||||
Be sure that the .socket file uses /run/cni/dhcp.sock as the socket path.
|
||||
|
||||
With the daemon running, containers using the dhcp plugin can be launched.
|
||||
|
||||
## Example configuration
|
||||
|
||||
```
|
||||
{
|
||||
"ipam": {
|
||||
"type": "dhcp",
|
||||
}
|
||||
}
|
||||

||||

# flannel plugin
|
||||
|
||||
## Overview
|
||||
This plugin is designed to work in conjunction with [flannel](https://github.com/coreos/flannel), a network fabric for containers.
|
||||
When flannel daemon is started, it outputs a `/run/flannel/subnet.env` file that looks like this:
|
||||
```
|
||||
FLANNEL_NETWORK=10.1.0.0/16
|
||||
FLANNEL_SUBNET=10.1.17.1/24
|
||||
FLANNEL_MTU=1472
|
||||
FLANNEL_IPMASQ=true
|
||||
```
|
||||
|
||||
This information reflects the attributes of flannel network on the host.
|
||||
The flannel CNI plugin uses this information to configure another CNI plugin, such as bridge plugin.
|
||||
|
||||
## Operation
|
||||
Given the following network configuration file and the contents of `/run/flannel/subnet.env` above,
|
||||
```
|
||||
{
|
||||
"name": "mynet",
|
||||
"type": "flannel"
|
||||
}
|
||||
```
|
||||
the flannel plugin will generate another network configuration file:
|
||||
```
|
||||
{
|
||||
"name": "mynet",
|
||||
"type": "bridge",
|
||||
"mtu": 1472,
|
||||
"ipMasq": false,
|
||||
"isGateway": true,
|
||||
"ipam": {
|
||||
"type": "host-local",
|
||||
"subnet": "10.1.17.0/24"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
It will then invoke the bridge plugin, passing it the generated configuration.
|
||||
|
||||
As can be seen from above, the flannel plugin, by default, will delegate to the bridge plugin.
|
||||
If additional configuration values need to be passed to the bridge plugin, it can be done so via the `delegate` field:
|
||||
```
|
||||
{
|
||||
"name": "mynet",
|
||||
"type": "flannel",
|
||||
"delegate": {
|
||||
"bridge": "mynet0",
|
||||
"mtu": 1400
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
This supplies a configuration parameter to the bridge plugin -- the created bridge will now be named `mynet0`.
|
||||
Notice that `mtu` has also been specified and this value will not be overwritten by flannel plugin.
|
||||
|
||||
Additionally, the `delegate` field can be used to select a different kind of plugin altogether.
|
||||
To use `ipvlan` instead of `bridge`, the following configuration can be specified:
|
||||
|
||||
```
|
||||
{
|
||||
"name": "mynet",
|
||||
"type": "flannel",
|
||||
"delegate": {
|
||||
"type": "ipvlan",
|
||||
"master": "eth0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Network configuration reference
|
||||
|
||||
* `name` (string, required): the name of the network
|
||||
* `type` (string, required): "flannel"
|
||||
* `subnetFile` (string, optional): full path to the subnet file written out by flanneld. Defaults to /run/flannel/subnet.env
|
||||
* `delegate` (dictionary, optional): specifies configuration options for the delegated plugin.
|
||||
|
||||
flannel plugin will always set the following fields in the delegated plugin configuration:
|
||||
|
||||
* `name`: value of its "name" field.
|
||||
* `ipam`: "host-local" type will be used with "subnet" set to `$FLANNEL_SUBNET`.
|
||||
|
||||
flannel plugin will set the following fields in the delegated plugin configuration if they are not present:
|
||||
* `ipMasq`: the inverse of `$FLANNEL_IPMASQ`
|
||||
* `mtu`: `$FLANNEL_MTU`
|
||||
|
||||
Additionally, for the bridge plugin, `isGateway` will be set to `true`, if not present.

# host-local plugin
|
||||
|
||||
## Overview
|
||||
|
||||
host-local IPAM plugin allocates IPv4 addresses out of a specified address range.
|
||||
It stores the state locally on the host filesystem, therefore ensuring uniqueness of IP addresses on a single host.
|
||||
|
||||
## Example configuration
|
||||
```
|
||||
{
|
||||
"ipam": {
|
||||
"type": "host-local",
|
||||
"subnet": "10.10.0.0/16",
|
||||
"rangeStart": "10.10.1.20",
|
||||
"rangeEnd": "10.10.3.50",
|
||||
"gateway": "10.10.0.254",
|
||||
"routes": [
|
||||
{ "dst": "0.0.0.0/0" },
|
||||
{ "dst": "192.168.0.0/16", "gw": "10.10.5.1" }
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Network configuration reference
|
||||
|
||||
* `type` (string, required): "host-local".
|
||||
* `subnet` (string, required): CIDR block to allocate out of.
|
||||
* `rangeStart` (string, optional): IP inside of "subnet" from which to start allocating addresses. Defaults to ".2" IP inside of the "subnet" block.
|
||||
* `rangeEnd` (string, optional): IP inside of "subnet" with which to end allocating addresses. Defaults to ".254" IP inside of the "subnet" block.
|
||||
* `gateway` (string, optional): IP inside of "subnet" to designate as the gateway. Defaults to ".1" IP inside of the "subnet" block.
|
||||
* `routes` (string, optional): list of routes to add to the container namespace. Each route is a dictionary with "dst" and optional "gw" fields. If "gw" is omitted, value of "gateway" will be used.
|
||||
|
||||
## Supported arguments
|
||||
The following [CNI_ARGS](https://github.com/appc/cni/blob/master/SPEC.md#parameters) are supported:
|
||||
|
||||
* `ip`: request a specific IP address from the subnet. If it's not available, the plugin will exit with an error
|
||||
|
||||
## Files
|
||||
|
||||
Allocated IP addresses are stored as files in /var/lib/cni/networks/$NETWORK_NAME.

# ipvlan plugin
|
||||
|
||||
## Overview
|
||||
|
||||
ipvlan is a new [addition](https://lwn.net/Articles/620087/) to the Linux kernel.
|
||||
Like its cousin macvlan, it virtualizes the host interface.
|
||||
However unlike macvlan which generates a new MAC address for each interface, ipvlan devices all share the same MAC.
|
||||
The kernel driver inspects the IP address of each packet when making a decision about which virtual interface should process the packet.
|
||||
|
||||
Because all ipvlan interfaces share the MAC address with the host interface, DHCP can only be used in conjunction with ClientID (currently not supported by DHCP plugin).
|
||||
|
||||
## Example configuration
|
||||
|
||||
```
|
||||
{
|
||||
"name": "mynet",
|
||||
"type": "ipvlan",
|
||||
"master": "eth0",
|
||||
"ipam": {
|
||||
"type": "host-local",
|
||||
"subnet": "10.1.2.0/24",
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Network configuration reference
|
||||
|
||||
* `name` (string, required): the name of the network.
|
||||
* `type` (string, required): "ipvlan".
|
||||
* `master` (string, required): name of the host interface to enslave.
|
||||
* `mode` (string, optional): one of "l2", "l3". Defaults to "l2".
|
||||
* `mtu` (integer, optional): explicitly set MTU to the specified value. Defaults to the value chosen by the kernel.
|
||||
* `ipam` (dictionary, required): IPAM configuration to be used for this network.
|
||||
|
||||
## Notes
|
||||
|
||||
* `ipvlan` does not allow virtual interfaces to communicate with the master interface.
|
||||
Therefore the container will not be able to reach the host via `ipvlan` interface.
|
||||
Be sure to also have container join a network that provides connectivity to the host (e.g. `ptp`).
|
||||
* A single master interface can not be enslaved by both `macvlan` and `ipvlan`.

# macvlan plugin
|
||||
|
||||
## Overview
|
||||
|
||||
[macvlan](http://backreference.org/2014/03/20/some-notes-on-macvlanmacvtap/) functions like a switch that is already connected to the host interface.
|
||||
A host interface gets "enslaved" with the virtual interfaces sharing the physical device but having distinct MAC addresses.
|
||||
Since each macvlan interface has its own MAC address, it makes it easy to use with existing DHCP servers already present on the network.
|
||||
|
||||
## Example configuration
|
||||
|
||||
```
|
||||
{
|
||||
"name": "mynet",
|
||||
"type": "macvlan",
|
||||
"master": "eth0",
|
||||
"ipam": {
|
||||
"type": "dhcp"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Network configuration reference
|
||||
|
||||
* `name` (string, required): the name of the network
|
||||
* `type` (string, required): "macvlan"
|
||||
* `master` (string, required): name of the host interface to enslave
|
||||
* `mode` (string, optional): one of "bridge", "private", "vepa", "passthrough". Defaults to "bridge".
|
||||
* `mtu` (integer, optional): explicitly set MTU to the specified value. Defaults to the value chosen by the kernel.
|
||||
* `ipam` (dictionary, required): IPAM configuration to be used for this network.
|
||||
|
||||
## Notes
|
||||
|
||||
* If are testing on a laptop, please remember that most wireless cards do not support being enslaved by macvlan.
|
||||
* A single master interface can not be enslaved by both `macvlan` and `ipvlan`.

# ptp plugin
|
||||
|
||||
## Overview
|
||||
The ptp plugin creates a point-to-point link between a container and the host by using a veth device.
|
||||
One end of the veth pair is placed inside a container and the other end resides on the host.
|
||||
The host-local IPAM plugin can be used to allocate an IP address to the container.
|
||||
The traffic of the container interface will be routed through the interface of the host.
|
||||
|
||||
## Example network configuration
|
||||
```
|
||||
{
|
||||
"name": "mynet",
|
||||
"type": "ptp",
|
||||
"ipam": {
|
||||
"type": "host-local",
|
||||
"subnet": "10.1.1.0/24"
|
||||
},
|
||||
"dns": {
|
||||
"nameservers": [ "10.1.1.1", "8.8.8.8" ]
|
||||
}
|
||||
}
|
||||
|
||||
## Network configuration reference
|
||||
|
||||
* `name` (string, required): the name of the network
|
||||
* `type` (string, required): "ptp"
|
||||
* `ipMasq` (boolean, optional): set up IP Masquerade on the host for traffic originating from this network and destined outside of it. Defaults to false.
|
||||
* `mtu` (integer, optional): explicitly set MTU to the specified value. Defaults to value chosen by the kernel.
|
||||
* `ipam` (dictionary, required): IPAM configuration to be used for this network.
|
||||
* `dns` (dictionary, optional): DNS information to return as described in the [Result](/SPEC.md#result).

# tuning plugin
|
||||
|
||||
## Overview
|
||||
|
||||
This plugin can change some system controls (sysctls) in the network namespace.
|
||||
It does not create any network interfaces and therefore does not bring connectivity by itself.
|
||||
It is only useful when used in addition to other plugins.
|
||||
|
||||
## Operation
|
||||
The following network configuration file
|
||||
```
|
||||
{
|
||||
"name": "mytuning",
|
||||
"type": "tuning",
|
||||
"sysctl": {
|
||||
"net.core.somaxconn": "500"
|
||||
}
|
||||
}
|
||||
```
|
||||
will set /proc/sys/net/core/somaxconn to 500.
|
||||
Other sysctls can be modified as long as they belong to the network namespace (`/proc/sys/net/*`).
|
||||
|
||||
A successful result would simply be:
|
||||
```
|
||||
{
|
||||
"cniVersion": "0.1.0"
|
||||
}
|
||||
```
|
||||
|
||||
## Network sysctls documentation
|
||||
|
||||
Some network sysctls are documented in the Linux sources:
|
||||
|
||||
- [Documentation/sysctl/net.txt](https://www.kernel.org/doc/Documentation/sysctl/net.txt)
|
||||
- [Documentation/networking/ip-sysctl.txt](https://www.kernel.org/doc/Documentation/networking/ip-sysctl.txt)

# Plugins
|
||||
Some CNI network plugins, maintained by the containernetworking team. For more information, see the [CNI website](https://www.cni.dev).
|
||||
# CNI - the Container Network Interface
|
||||
|
||||
Read [CONTRIBUTING](CONTRIBUTING.md) for build and test instructions.
|
||||
## What is CNI?
|
||||
|
||||
## Plugins supplied:
|
||||
### Main: interface-creating
|
||||
* `bridge`: Creates a bridge, adds the host and the container to it.
|
||||
* `ipvlan`: Adds an [ipvlan](https://www.kernel.org/doc/Documentation/networking/ipvlan.txt) interface in the container.
|
||||
* `loopback`: Set the state of loopback interface to up.
|
||||
* `macvlan`: Creates a new MAC address, forwards all traffic to that to the container.
|
||||
* `ptp`: Creates a veth pair.
|
||||
* `vlan`: Allocates a vlan device.
|
||||
* `host-device`: Move an already-existing device into a container.
|
||||
#### Windows: Windows specific
|
||||
* `win-bridge`: Creates a bridge, adds the host and the container to it.
|
||||
* `win-overlay`: Creates an overlay interface to the container.
|
||||
### IPAM: IP address allocation
|
||||
* `dhcp`: Runs a daemon on the host to make DHCP requests on behalf of the container
|
||||
* `host-local`: Maintains a local database of allocated IPs
|
||||
* `static`: Allocate a static IPv4/IPv6 addresses to container and it's useful in debugging purpose.
|
||||
CNI, the _Container Network Interface_, is a proposed standard for configuring network interfaces for Linux application containers.
|
||||
The standard consists of a simple specification for how executable plugins can be used to configure network namespaces; this repository also contains a go library implementing that specification.
|
||||
|
||||
### Meta: other plugins
|
||||
* `tuning`: Tweaks sysctl parameters of an existing interface
|
||||
* `portmap`: An iptables-based portmapping plugin. Maps ports from the host's address space to the container.
|
||||
* `bandwidth`: Allows bandwidth-limiting through use of traffic control tbf (ingress/egress).
|
||||
* `sbr`: A plugin that configures source based routing for an interface (from which it is chained).
|
||||
* `firewall`: A firewall plugin which uses iptables or firewalld to add rules to allow traffic to/from the container.
|
||||
The specification itself is contained in [SPEC.md](SPEC.md).
|
||||
|
||||
### Sample
|
||||
The sample plugin provides an example for building your own plugin.
|
||||
## Why develop CNI?
|
||||
|
||||
Application containers on Linux are a rapidly evolving area, and within this space networking is a particularly unsolved problem, as it is highly environment-specific.
|
||||
We believe that every container runtime will seek to solve the same problem of making the network layer pluggable.
|
||||
|
||||
To avoid duplication, we think it is prudent to define a common interface between the network plugins and container execution.
|
||||
Hence we are proposing this specification, along with an initial set of plugins that can be used by different container runtime systems.
|
||||

|
||||
|
||||
## How do I use CNI?
|
||||
|
||||
### Requirements
|
||||
CNI requires Go 1.5+ to build.
|
||||
|
||||
Go 1.5 users will need to set GO15VENDOREXPERIMENT=1 to get vendored
|
||||
dependencies. This flag is set by default in 1.6.
|
||||
|
||||
### Included Plugins
|
||||
This repository includes a number of common plugins in the `plugins/` directory.
|
||||
Please see the [Documentation/](Documentation/) directory for documentation about particular plugins.
|
||||
|
||||
### Running the plugins
|
||||
The scripts/ directory contains two scripts, `priv-net-run.sh` and `docker-run.sh`, that can be used to exercise the plugins.
|
||||
|
||||
**note - priv-net-run.sh depends on `jq`**
|
||||
|
||||
Start out by creating a netconf file to describe a network:
|
||||
|
||||
```bash
|
||||
$ mkdir -p /etc/cni/net.d
|
||||
$ cat >/etc/cni/net.d/10-mynet.conf <<EOF
|
||||
{
|
||||
"name": "mynet",
|
||||
"type": "bridge",
|
||||
"bridge": "cni0",
|
||||
"isGateway": true,
|
||||
"ipMasq": true,
|
||||
"ipam": {
|
||||
"type": "host-local",
|
||||
"subnet": "10.22.0.0/16",
|
||||
"routes": [
|
||||
{ "dst": "0.0.0.0/0" }
|
||||
]
|
||||
}
|
||||
}
|
||||
EOF
|
||||
$ cat >/etc/cni/net.d/99-loopback.conf <<EOF
|
||||
{
|
||||
"type": "loopback"
|
||||
}
|
||||
EOF
|
||||
```
|
||||
|
||||
The directory `/etc/cni/net.d` is the default location in which the scripts will look for net configurations.
|
||||
|
||||
Next, build the plugins:
|
||||
|
||||
```bash
|
||||
$ ./build
|
||||
```
|
||||
|
||||
Finally, execute a command (`ifconfig` in this example) in a private network namespace that has joined the `mynet` network:
|
||||
|
||||
```bash
|
||||
$ CNI_PATH=`pwd`/bin
|
||||
$ cd scripts
|
||||
$ sudo CNI_PATH=$CNI_PATH ./priv-net-run.sh ifconfig
|
||||

|
||||
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
|
||||
```
|
||||
|
||||
The environment variable `CNI_PATH` tells the scripts and library where to look for plugin executables.
|
||||
|
||||
## Running a Docker container with network namespace set up by CNI plugins
|
||||
|
||||
Use the instructions in the previous section to define a netconf and build the plugins.
|
||||
Next, docker-run.sh script wraps `docker run`, to execute the plugins prior to entering the container:
|
||||
|
||||
```bash
|
||||
$ CNI_PATH=`pwd`/bin
|
||||
$ cd scripts
|
||||
$ sudo CNI_PATH=$CNI_PATH ./docker-run.sh --rm busybox:latest ifconfig

# Release process
|
||||
|
||||
## Resulting artifacts
|
||||
Creating a new release produces the following artifacts:
|
||||
|
||||
- Binaries (stored in the `release-<TAG>` directory) :
|
||||
- `cni-plugins-<PLATFORM>-<VERSION>.tgz` binaries
|
||||
- `cni-plugins-<VERSION>.tgz` binary (copy of amd64 platform binary)
|
||||
- `sha1`, `sha256` and `sha512` files for the above files.
|
||||
|
||||
## Preparing for a release
|
||||
1. Releases are performed by maintainers and should usually be discussed and planned at a maintainer meeting.
|
||||
- Choose the version number. It should be prefixed with `v`, e.g. `v1.2.3`
|
||||
- Take a quick scan through the PRs and issues to make sure there isn't anything crucial that _must_ be in the next release.
|
||||
- Create a draft of the release note
|
||||
- Discuss the level of testing that's needed and create a test plan if sensible
|
||||
- Check what version of `go` is used in the build container, updating it if there's a new stable release.
|
||||
- Update the vendor directory and Godeps to pin to the corresponding containernetworking/cni release. Create a PR, makes sure it passes CI and get it merged.
|
||||
|
||||
## Creating the release artifacts
|
||||
1. Make sure you are on the master branch and don't have any local uncommitted changes.
|
||||
1. Create a signed tag for the release `git tag -s $VERSION` (Ensure that GPG keys are created and added to GitHub)
|
||||
1. Run the release script from the root of the repository
|
||||
- `scripts/release.sh`
|
||||
- The script requires Docker and ensures that a consistent environment is used.
|
||||
- The artifacts will now be present in the `release-<TAG>` directory.
|
||||
1. Test these binaries according to the test plan.
|
||||
|
||||
## Publishing the release
|
||||
1. Push the tag to git `git push origin <TAG>`
|
||||
1. Create a release on Github, using the tag which was just pushed.
|
||||
1. Attach all the artifacts from the release directory.
|
||||
1. Add the release note to the release.
|
||||
1. Announce the release on at least the CNI mailing, IRC and Slack.

# Container Networking Interface Proposal
|
||||
|
||||
## Overview
|
||||
|
||||
This document proposes a generic plugin-based networking solution for application containers on Linux, the _Container Networking Interface_, or _CNI_.
|
||||
It is derived from the [rkt Networking Proposal][rkt-networking-proposal], which aimed to satisfy many of the [design considerations][rkt-networking-design] for networking in [rkt][rkt-github].
|
||||
|
||||
For the purposes of this proposal, we define two terms very specifically:
|
||||
- _container_ can be considered synonymous with a [Linux _network namespace_][namespaces]. What unit this corresponds to depends on a particular container runtime implementation: for example, in implementations of the [App Container Spec][appc-github] like rkt, each _pod_ runs in a unique network namespace. In [Docker][docker], on the other hand, network namespaces generally exist for each separate Docker container.
|
||||
- _network_ refers to a group of entities that are uniquely addressable that can communicate amongst each other. This could be either an individual container (as specified above), a machine, or some other network device (e.g. a router). Containers can be conceptually _added to_ or _removed from_ one or more networks.
|
||||
|
||||
[rkt-networking-proposal]: https://docs.google.com/a/coreos.com/document/d/1PUeV68q9muEmkHmRuW10HQ6cHgd4819_67pIxDRVNlM/edit#heading=h.ievko3xsjwxd

|
||||
[appc-github]: https://github.com/appc/spec
|
||||
[docker]: https://docker.com
|
||||
|
||||
## General considerations
|
||||
|
||||
The intention is for the container runtime to first create a new network namespace for the container.
|
||||
It then determines which networks this container should belong to and for each network, which plugin must be executed.
|
||||
The network configuration is in JSON format and can easily be stored in a file.
|
||||
The network configuration includes mandatory fields such as "name" and "type" as well as plugin (type) specific ones.
|
||||
The container runtime sequentially sets up the networks by executing the corresponding plugin for each network.
|
||||
Upon completion of the container lifecycle, the runtime executes the plugins in reverse order (relative to the order in which they were added) to disconnect them from the networks.
|
||||
|
||||
## CNI Plugin
|
||||
|
||||
### Overview
|
||||
|
||||
Each CNI plugin is implemented as an executable that is invoked by the container management system (e.g. rkt or Docker).
|
||||
|
||||
A CNI plugin is responsible for inserting a network interface into the container network namespace (e.g. one end of a veth pair) and making any necessary changes on the host (e.g. attaching other end of veth into a bridge).
|
||||
It should then assign the IP to the interface and setup the routes consistent with IP Address Management section by invoking appropriate IPAM plugin.
|
||||
|
||||
### Parameters
|
||||
|
||||
The operations that the CNI plugin needs to support are:
|
||||
|
||||
|
||||
- Add container to network
|
||||
- Parameters:
|
||||
- **Version**. The version of CNI spec that the caller is using (container management system or the invoking plugin).
|
||||
- **Container ID**. This is optional but recommended, and should be unique across an administrative domain while the container is live (it may be reused in the future). For example, an environment with an IPAM system may require that each container is allocated a unique ID and that each IP allocation can thus be correlated back to a particular container. As another example, in appc implementations this would be the _pod ID_.
|
||||
- **Network namespace path**. This represents the path to the network namespace to be added, i.e. /proc/[pid]/ns/net or a bind-mount/link to it.
|
||||
- **Network configuration**. This is a JSON document describing a network to which a container can be joined. The schema is described below.
|
||||
- **Extra arguments**. This allows granular configuration of CNI plugins on a per-container basis.
|
||||
- **Name of the interface inside the container**. This is the name that should be assigned to the interface created inside the container (network namespace); consequently it must comply with the standard Linux restrictions on interface names.
|
||||
- Result:
|
||||
- **IPs assigned to the interface**. This is either an IPv4 address, an IPv6 address, or both.
|
||||
- **DNS information**. Dictionary that includes DNS information for nameservers, domain, search domains and options.
|
||||
|
||||
- Delete container from network
|
||||
- Parameters:
|
||||
- **Version**. The version of CNI spec that the caller is using (container management system or the invoking plugin).
|
||||
- **Container ID**, as defined above.
|
||||
- **Network namespace path**, as defined above.
|
||||
- **Network configuration**, as defined above.
|
||||
- **Extra arguments**, as defined above.
|
||||
- **Name of the interface inside the container**, as defined above.
|
||||
|
||||
The executable command-line API uses the type of network (see [Network Configuration](#network-configuration) below) as the name of the executable to invoke.
|
||||
It will then look for this executable in a list of predefined directories. Once found, it will invoke the executable using the following environment variables for argument passing:
|
||||
- `CNI_VERSION`: [Semantic Version 2.0](http://semver.org) of CNI specification. This effectively versions the CNI_XXX environment variables.
|
||||
- `CNI_COMMAND`: indicates the desired operation; either `ADD` or `DEL`
|
||||
- `CNI_CONTAINERID`: Container ID
|
||||
- `CNI_NETNS`: Path to network namespace file
|
||||
- `CNI_IFNAME`: Interface name to set up
|
||||
- `CNI_ARGS`: Extra arguments passed in by the user at invocation time. Alphanumeric key-value pairs separated by semicolons; for example, "FOO=BAR;ABC=123"
|
||||
- `CNI_PATH`: Colon-separated list of paths to search for CNI plugin executables
|
||||
|
||||
Network configuration in JSON format is streamed through stdin.
|
||||
|
||||
|
||||
### Result
|
||||
|
||||
Success is indicated by a return code of zero and the following JSON printed to stdout in the case of the ADD command. This should be the same output as was returned by the IPAM plugin (see [IP Allocation](#ip-allocation) for details).
|
||||
|
||||
```
|
||||
{
|
||||
"cniVersion": "0.1.0",
|
||||
"ip4": {
|
||||
"ip": <ipv4-and-subnet-in-CIDR>,
|
||||
"gateway": <ipv4-of-the-gateway>, (optional)
|

|
||||
},

### Network Configuration
|
||||
|
||||
The network configuration is described in JSON form. The configuration can be stored on disk or generated from other sources by the container runtime. The following fields are well-known and have the following meaning:
|
||||
- `cniVersion` (string): [Semantic Version 2.0](http://semver.org) of CNI specification to which this configuration conforms.
|
||||
- `name` (string): Network name. This should be unique across all containers on the host (or other administrative domain).
|
||||
- `type` (string): Refers to the filename of the CNI plugin executable.
|
||||
- `ipMasq` (boolean): Optional (if supported by the plugin). Set up an IP masquerade on the host for this network. This is necessary if the host will act as a gateway to subnets that are not able to route to the IP assigned to the container.
|
||||
- `ipam`: Dictionary with IPAM specific values:
|
||||
- `type` (string): Refers to the filename of the IPAM plugin executable.
|
||||
- `routes` (list): List of subnets (in CIDR notation) that the CNI plugin should ensure are reachable by routing them through the network. Each entry is a dictionary containing:
|
||||
- `dst` (string): subnet in CIDR notation
|
||||
- `gw` (string): IP address of the gateway to use. If not specified, the default gateway for the subnet is assumed (as determined by the IPAM plugin).
|
||||
- `dns`: Dictionary with DNS specific values:
|
||||
- `nameservers` (list of strings): list of a priority-ordered list of DNS nameservers that this network is aware of. Each entry in the list is a string containing either an IPv4 or an IPv6 address.
|
||||
- `domain` (string): the local domain used for short hostname lookups.
|
||||
- `search` (list of strings): list of priority ordered search domains for short hostname lookups. Will be preferred over `domain` by most resolvers.
|
||||
- `options` (list of strings): list of options that can be passed to the resolver
|
||||
|
||||

|

}
|

}
|
||||
```
|
||||
|
||||
|
||||
### IP Allocation
|
||||
|
||||
As part of its operation, a CNI plugin is expected to assign (and maintain) an IP address to the interface and install any necessary routes relevant for that interface. This gives the CNI plugin great flexibility but also places a large burden on it. Many CNI plugins would need to have the same code to support several IP management schemes that users may desire (e.g. dhcp, host-local).
|
||||
|
||||
To lessen the burden and make IP management strategy be orthogonal to the type of CNI plugin, we define a second type of plugin -- IP Address Management Plugin (IPAM plugin). It is however the responsibility of the CNI plugin to invoke the IPAM plugin at the proper moment in its execution. The IPAM plugin is expected to determine the interface IP/subnet, Gateway and Routes and return this information to the "main" plugin to apply. The IPAM plugin may obtain the information via a protocol (e.g. dhcp), data stored on a local filesystem, the "ipam" section of the Network Configuration file or a combination of the above.
|
||||
|
||||
#### IP Address Management (IPAM) Interface
|
||||
|
||||
Like CNI plugins, the IPAM plugins are invoked by running an executable. The executable is searched for in a predefined list of paths, indicated to the CNI plugin via `CNI_PATH`. The IPAM Plugin receives all the same environment variables that were passed in to the CNI plugin. Just like the CNI plugin, IPAM receives the network configuration file via stdin.
|
||||
|
||||
Success is indicated by a zero return code and the following JSON being printed to stdout (in the case of the ADD command):
|
||||
|
||||
```
|
||||
{
|
||||
"cniVersion": "0.1.0",
|
||||
"ip4": {
|
||||
"ip": <ipv4-and-subnet-in-CIDR>,
|
||||
"gateway": <ipv4-of-the-gateway>, (optional)
|
||||
"routes": <list-of-ipv4-routes> (optional)
|
||||
},
|
||||
"ip6": {
|
||||
"ip": <ipv6-and-subnet-in-CIDR>,
|
||||
"gateway": <ipv6-of-the-gateway>, (optional)
|
||||
"routes": <list-of-ipv6-routes> (optional)
|
||||
},
|
||||
"dns": {
|
||||
"nameservers": <list-of-nameservers> (optional)
|
||||
"domain": <name-of-local-domain> (optional)
|
||||
"search": <list-of-search-domains> (optional)
|
||||
"options": <list-of-options> (optional)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
`cniVersion` specifies a [Semantic Version 2.0](http://semver.org) of CNI specification used by the plugin.
|
||||
`gateway` is the default gateway for this subnet, if one exists.
|
||||
It does not instruct the CNI plugin to add any routes with this gateway: routes to add are specified separately via the `routes` field.
|
||||
An example use of this value is for the CNI plugin to add this IP address to the linux-bridge to make it a gateway.
|
||||
|
||||
Each route entry is a dictionary with the following fields:
|
||||
- `dst` (string): Destination subnet specified in CIDR notation.
|
||||
- `gw` (string): IP of the gateway. If omitted, a default gateway is assumed (as determined by the CNI plugin).
|
||||
|
||||
The "dns" field contains a dictionary consisting of common DNS information.
|
||||
- `nameservers` (list of strings): list of a priority-ordered list of DNS nameservers that this network is aware of. Each entry in the list is a string containing either an IPv4 or an IPv6 address.
|
||||
- `domain` (string): the local domain used for short hostname lookups.
|
||||
- `search` (list of strings): list of priority ordered search domains for short hostname lookups. Will be preferred over `domain` by most resolvers.
|
||||
- `options` (list of strings): list of options that can be passed to the resolver
|
||||
See [CNI Plugin Result](#result) section for more information.
|
||||
|
||||
Errors and logs are communicated in the same way as the CNI plugin. See [CNI Plugin Result](#result) section for details.
|
||||
|
||||
IPAM plugin examples:
|
||||
- **host-local**: Select an unused (by other containers on the same host) IP within the specified range.
|
||||
- **dhcp**: Use DHCP protocol to acquire and maintain a lease. The DHCP requests will be sent via the created container interface; therefore, the associated network must support broadcast.
|
||||
|
||||
#### Notes
|
||||
- Routes are expected to be added with a 0 metric.
|
||||
- A default route may be specified via "0.0.0.0/0". Since another network might have already configured the default route, the CNI plugin should be prepared to skip over its default route definition.

### Namespaces, Threads, and Go
|
||||
On Linux each OS thread can have a different network namespace. Go's thread scheduling model switches goroutines between OS threads based on OS thread load and whether the goroutine would block other goroutines. This can result in a goroutine switching network namespaces without notice and lead to errors in your code.
|
||||
|
||||
### Namespace Switching
|
||||
Switching namespaces with the `ns.Set()` method is not recommended without additional strategies to prevent unexpected namespace changes when your goroutines switch OS threads.
|
||||
|
||||
Go provides the `runtime.LockOSThread()` function to ensure a specific goroutine executes on its current OS thread and prevents any other goroutine from running in that thread until the locked one exits. Careful usage of `LockOSThread()` and goroutines can provide good control over which network namespace a given goroutine executes in.
|
||||
|
||||
For example, you cannot rely on the `ns.Set()` namespace being the current namespace after the `Set()` call unless you do two things. First, the goroutine calling `Set()` must have previously called `LockOSThread()`. Second, you must ensure `runtime.UnlockOSThread()` is not called somewhere in-between. You also cannot rely on the initial network namespace remaining the current network namespace if any other code in your program switches namespaces, unless you have already called `LockOSThread()` in that goroutine. Note that `LockOSThread()` prevents the Go scheduler from optimally scheduling goroutines for best performance, so `LockOSThread()` should only be used in small, isolated goroutines that release the lock quickly.
|
||||
|
||||
### Do() The Recommended Thing

The `ns.Do()` method provides **partial** control over network namespaces for you by implementing these strategies. All code dependent on a particular network namespace (including the root namespace) should be wrapped in the `ns.Do()` method to ensure the correct namespace is selected for the duration of your code. For example:
|
||||
|
||||
```go
|
||||
err = targetNs.Do(func(hostNs ns.NetNS) error {
|
||||
dummy := &netlink.Dummy{
|
||||
LinkAttrs: netlink.LinkAttrs{
|
||||
Name: "dummy0",
|
||||
},
|
||||
}
|
||||
return netlink.LinkAdd(dummy)
|
||||
})
|
||||
```
|
||||
|
||||
Note this requirement to wrap every network call is very onerous - any libraries you call might call out to network services such as DNS, and all such calls need to be protected after you call `ns.Do()`. All goroutines spawned from within the `ns.Do` will not inherit the new namespace. The CNI plugins all exit very soon after calling `ns.Do()` which helps to minimize the problem.
|
||||
|
||||
When a new thread is spawned in Linux, it inherits the namespace of its parent. In versions of go **prior to 1.10**, if the runtime spawns a new OS thread, it picks the parent randomly. If the chosen parent thread has been moved to a new namespace (even temporarily), the new OS thread will be permanently "stuck in the wrong namespace", and goroutines will non-deterministically switch namespaces as they are rescheduled.
|
||||
|
||||
In short, **there was no safe way to change network namespaces, even temporarily, from within a long-lived, multithreaded Go process**. If you wish to do this, you must use go 1.10 or greater.
|
||||
|
||||
|
||||
### Creating network namespaces
|
||||
Earlier versions of this library managed namespace creation, but as CNI does not actually utilize this feature (and it was essentially unmaintained), it was removed. If you're writing a container runtime, you should implement namespace management yourself. However, there are some gotchas when doing so, especially around handling `/var/run/netns`. A reasonably correct reference implementation, borrowed from `rkt`, can be found in `pkg/testutils/netns_linux.go` if you're in need of a source of inspiration.
