- Renamed `ipxeBaseURL` to more generic `bootArtifactsBaseURL` - Removed unwanted lint - Added integration tests to create minimal ISO for external platform with and without bootArtifactsBaseURL in agent-config.yaml - Fixed existing integration tests to include change of name from `ipxeBaseURL` to more generic `bootArtifactsBaseURL` - Added BootArtifactsBaseUrl and bootArtifactsPath into parent asset AgentArtifacts - AgentArtifacts also depends on AgentConfig asset - Moved common code to generate rootfs.img file into extractRootFS() in AgentArtifacts asset - If the bootArtifactsBaseURL is specified, construct the custom rootfs URL otherwise default to the URL from the RHCOS streams file - For external platform when the bootArtifactsBaseUrl is specified, output the rootfs file alongside the minimal ISO - For all other platforms, continue generating full ISO (no explicit rootfs.img is generated) - Vendor changes after updating github.com/openshift/assisted-image-service dependency - set IMAGE_TYPE_ISO to 'minimal-iso' in create-cluster-and-infraenv.service.template when using external platform - Log an info message to upload CCM manifests Signed-off-by: Pawan Pinjarkar <ppinjark@redhat.com>
