Sample deployment of a new server

In this section we describe the deployment of a new server from scratch. All the operations will be performed using bob, the command-line client for interacting with sysdb.

The informations we need are:

the server name: logging-ra.psi.ch
the server MAC address: 23:3d:ef:33:11:22
optional static or dynamic IP: static (RHEL7 & RHEL8 only)
the OS installer: rhel8install
the server role: role::logging_server
optional the server environment in puppet: prod
the sysdb deployment environment: daas
optional the group inside the sysdb environment (default if not specified): logging
optional the subgroup inside the group: collector

Setting up bob

The bob tool is already set up on lxsup.psi.ch. You might connect with ssh and use it from there.

Altenatively you many have on your workstation a local copy of bob. This can be done by installing the RPM from the pli-misc repository - https://repos.psi.ch/rhel8/latest/pli-misc/

You might need to set a PSI_BOB_USER environment variable (export PSI_BOB_USER=<you-name-it>) or use the option --user if your local user is different from the one on sysdb.

Sysdb configuration

We add the node to the environment, specifing netboot as the boot action

bob node add logging-ra.psi.ch daas netboot

We setup its MAC address:

bob node add-mac logging-ra.psi.ch 23:3d:ef:33:11:22

Next decide how the IP address is configured (dhcp or static):

bob node set-attr logging-ra.psi.ch network=static

And which installer is used:

bob node set-attr logging-ra.psi.ch ipxe_installer=rhel8install

And we finally setup the puppet role and puppet environment:

bob node set-attr logging-ra.psi.ch puppet_role=role::log_server
bob node set-attr logging-ra.psi.ch puppet_env=prod
bob node set-attr logging-ra.psi.ch puppet_group=logging
bob node set-attr logging-ra.psi.ch puppet_subgroup=collector

Example

Full example:

bob node add lx-test-02.psi.ch lx netboot
bob node add-mac lx-test-02 00:50:56:9d:19:76
bob node set-attr lx-test-02.psi.ch ipxe_installer=rhel8install puppet_role=role::server
bob node netboot lx-test-02.psi.ch
bob node list -v lx-test-02

Ensure that a potential previous puppet certificate for this server is deleted on the puppet server: https://puppet.psi.ch

Special Settings

Custom Kernel Commandline Arguments

For custom kernel commandline arguments for the installer (e.g. to provide drivers) the sysdb attribute kernel_cmdline can be used:

bob node set-attr lx-test-02.psi.ch kernel_cmdline=inst.dd=https://linuxsoft.cern.ch/elrepo/dud/el8/x86_64/dd-megaraid_sas-07.725.01.00-1.el8_9.elrepo.iso
