What needs to get done
Add support for pinning the build and build-base images in the rockcraft descriptors to an existing image diggest
Why it needs to get done
The motivation for this request is twofold:
- Support repeatable builds, with all the advantages this entails
- Trigger new builds when the base or build-base image changes using widely adopted mechanisms like renovate. Right now there's a workaround to support this but since the base images are not pinned the resulting OCI image can be updated alongside any other change before the PR is merged
