Every standalone workspace-template repo now publishes to
ghcr.io/molecule-ai/workspace-template-<runtime>:latest via the
reusable publish-template-image workflow in molecule-ci (landed
today — one caller per template repo). This PR makes the
provisioner actually use those images:
- RuntimeImages map + DefaultImage switched from bare local tags
(workspace-template:<runtime>) to their GHCR equivalents.
- New ensureImageLocal step before ContainerCreate: if the image
isn't present locally, attempt `docker pull` and drain the
progress stream to completion. Best-effort — if the pull fails
(network, auth, rate limit) the subsequent ContainerCreate still
surfaces the actionable "No such image" error, now with a
GHCR-appropriate hint instead of the defunct
`bash workspace/build-all.sh <runtime>` advice.
- runtimeTagFromImage now handles both forms: legacy
`workspace-template:<runtime>` (local dev via build-all.sh /
rebuild-runtime-images.sh) and the current GHCR shape. Keeps
error hints sensible in both worlds.
- Tests cover the GHCR path for tag extraction and the new error
message shape. Legacy local tags still recognised.
Local dev path unchanged — scripts/build-images.sh and
workspace/rebuild-runtime-images.sh still produce locally-tagged
`workspace-template:<runtime>` images, and Docker's image
resolver matches them before any pull is attempted. So
contributors can keep iterating on a template repo without
round-tripping through GHCR.
Follow-on impact:
- hongmingwang.moleculesai.app (and any other tenant EC2) will
auto-pull `ghcr.io/molecule-ai/workspace-template-hermes:latest`
on the next hermes workspace provision — picking up the real
Nous hermes-agent behind the A2A bridge (template-hermes v2.1.0)
without any tenant-side rebuild step.
