ansible-role-pxe_config

Configures PXE

Requirements

a hosts file that looks like this:

[compute]
node1 int_ip_addr=10.1.2.1 ib_ip_addr=10.2.2.1 mac_address=00:11:22:33:44:55
node2 int_ip_addr=10.1.2.2 ib_ip_addr=10.2.2.2 mac_address=00:11:22:33:44:56

[pxe_bootable_nodes:children]
compute

Role Variables

intDomain: "fgci.csc.fi"

siteName: "io"

These are the defaults:

hosts_file_pxe_group_to_populate: "{{ groups.pxe_bootable_nodes }}"
hosts_file_admin_group_to_populate: "{{ groups.admin }}"
hosts_file_install_group_to_populate: "{{ groups.install }}"
hosts_file_login_group_to_populate: "{{ groups.login }}"
hosts_file_extra_group_to_populate: ""

By setting the above to "" we disable that group. So let's say you only want to populate the production group, set the variables like so:

hosts_file_pxe_group_to_populate: "{{ groups.production }}"
hosts_file_admin_group_to_populate: ""
hosts_file_install_group_to_populate: ""
hosts_file_login_group_to_populate: ""
hosts_file_extra_group_to_populate: ""

Using the custom inventory script to only write kickstart templates once per child group of a group by:

hosts_file_group_to_populate: "pxe_bootable_nodes"
hosts_file_inventory_location: "hosts"

See defaults/main.yml for some examples

Dependencies

• currently tightly integrated with dhcp_server and pxe_bootstrap

  • https://github.com/CSCfi/ansible-role-pxe\_bootstrap
  • https://github.com/CSCfi/ansible-role-dhcp\_server

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: servers
  roles:
     - { role: ansible-role-pxe_config }

Result

The tests we run are in here: https://github.com/CSCfi/ansible-role-pxe_config/tree/master/tests

They generate a hosts file that looks like this:

10.1.100.1 io1 io1.int.fgci.csc.fi
10.2.100.1 io1-ib io1-ib.int.fgci.csc.fi
10.1.1.6 io-admin io-admin io-admin.int.fgci.csc.fi io-admin.int.fgci.csc.fi
10.1.1.8 io-install io-install io-install.int.fgci.csc.fi io-install.int.fgci.csc.fi
