User Story:

As an Azure user, I want my installs to automatically use free Azure images, so that installs are much quicker.

Acceptance Criteria:

Description of criteria:

• Free marketplace image is read from rhcos stream
• Cluster is installed using that image by default
• OKD continues with image upload (for now)

(optional) Out of Scope:

Detail about what is specifically not being delivered in the story

Engineering Details:

• RHCOS asset for azure is set here: https://github.com/openshift/installer/blob/main/pkg/asset/rhcos/image.go#L135-L146
• OSImage is set for CAPI control plane here: https://github.com/openshift/installer/blob/main/pkg/asset/machines/azure/azuremachines.go#L63-L91
• For MAPI, here: https://github.com/openshift/installer/blob/main/pkg/asset/machines/azure/machines.go#L175-L200
• It is possible both the above should be refactored into the RHCOS asset
• Azure image upload is handled here: https://github.com/openshift/installer/blob/main/pkg/infrastructure/azure/azure.go#L259
  • This will need to check the rhcos asset (or equivalent). This should be skipped by default, except for okd

Testing Details:

• Testing should be transparent. This will switch the default. Make sure to test GovCloud or MAG or whatever it's called.
