Add two interfaces (e.g. eth0, eth1) to the same container.
Ensure each file now has ContainerID and ifname.
Delete one, ensure that the right file was deleted.
Add an interface using just ContainerID in the file.
Delete to verify we are still backwards compatible with any
files created using earlier verison of host-local plugin.
Recent CNI specification changes require the container ID on ADD/DEL,
which the testcases were not providing. Fix that up so things work
when this repo gets CNI revendored.
In real-world address allocations, disjoint address ranges are common.
Therefore, the host-local allocator should support them.
This change still allows for multiple IPs in a single configuration, but
also allows for a "set of subnets."
Fixes: #45
This change allows the host-local allocator to allocate multiple IPs.
This is intended to enable dual-stack, but is not limited to only two
subnets or separate address families.
Updates the spec and plugins to return an array of interfaces and IP details
to the runtime including:
- interface names and MAC addresses configured by the plugin
- whether the interfaces are sandboxed (container/VM) or host (bridge, veth, etc)
- multiple IP addresses configured by IPAM and which interface they
have been assigned to
Returning interface details is useful for runtimes, as well as allowing
more flexible chaining of CNI plugins themselves. For example, some
meta plugins may need to know the host-side interface to be able to
apply firewall or traffic shaping rules to the container.
This adds the option `resolvConf` to the host-local IPAM configuration.
If specified, the plugin will try to parse the file as a resolv.conf(5)
type file and return it in the DNS response.
It doesn't seem like container IDs should really have whitespace or
newlines in them. As a complete edge-case, manipulating the host-local
store's IP reservations with 'echo' puts a newline at the end, which
caused matching to fail in ReleaseByID(). Don't ask...
Add an e2e host-local plugin testcase, which requires being able
to pass the datadir into the plugin so we can erase it later.
We're not always guaranteed to have access to the default data
dir location, plus it should probably be configurable anyway.
