Ironic Python Agent (IPA)¶

Release Train IPA¶

StackHPC provides prebuilt Ironic Python Agent (IPA) images in Release Train through Ark.

These images are built in CI using a GitHub workflow and are configured in this repository. See Kayobe documentation for more details on IPA.

Release Train IPA images are used by Bifrost and Overcloud Ironic by default in the StackHPC Kayobe Configuration, and are pulled in to the Ironic Inspector when running kayobe seed service deploy for Bifrost or kayobe overcloud post configure for Overcloud Ironic. This behaviour can be disabled in stackhpc-ipa-images.yml:

stackhpc_ipa_image_bifrost_enabled: false
stackhpc_ipa_image_overcloud_enabled: false

You can also select the architecture of the IPA images pulled in during deployment:

stackhpc_ipa_arch: aarch64

The supported values are amd64 and aarch64. Rocky Linux 9 uses stackhpc_rocky_9_ipa_image_version for amd64 and stackhpc_rocky_9_ipa_image_version_aarch64 for aarch64.

You can also override the distribution version pulled in during deployment. For example, the case of switching to Ubuntu 24.04 on a Rocky 9 cloud:

stackhpc_ipa_image_version: "{{ stackhpc_ubuntu_noble_ipa_image_version }}"
