fdp_update_container_images

Ansible role to update specific RPM packages in OpenStack container images by rebuilding them with custom repositories.

This role automates the process of:

  1. Fetching container images from OpenStackVersion CR

  2. Checking if target package exists in each image

  3. Building new images with updated packages from custom repository

  4. Pushing updated images to OpenShift internal registry

  5. Patching OpenStackVersion CR to use the new images

Privilege escalation

None - Runs as the user executing Ansible

How it works

  1. Registry Setup:

    • Enables the default route for OpenShift image registry

    • Auto-detects the registry hostname or uses the configured value

  2. Authentication: Obtains a token from OpenShift and authenticates with the internal registry using TLS

  3. Image Discovery: Queries the OpenStackVersion CR for all container images

  4. Package Check: For each image, creates a temporary container to check if the target package is installed

  5. Image Build: If the package exists, builds a new image with the updated package from the custom repository

  6. Registry Push: Pushes the new image to the OpenShift internal registry

  7. CR Update: Patches the OpenStackVersion CR’s spec.customContainerImages field with the new image reference

  8. Summary: Provides a summary of all updated images

Requirements

  • OpenShift CLI (oc) must be available

  • Podman must be installed and accessible

  • User must have permissions to:

    • Create tokens in the target namespace

    • Get and patch OpenStackVersion CRs

    • Push images to the internal registry

    • Patch image registry configuration (configs.imageregistry.operator.openshift.io/cluster)

Notes

  • The role uses podman to build and push images with TLS verification

  • Each updated image gets a unique tag with timestamp: <prefix>-<image-key>-<timestamp>

  • Only images containing the target package will be updated

  • The role cleans up temporary containers automatically

  • All build contexts are created in a temporary directory that is cleaned up after execution

  • The role automatically configures the OpenShift image registry for external access:

    • Enables the default route if not already enabled

    • Auto-detects the registry hostname from the route
