Is this Docker Desktop?

No. Harbor stores and serves images. Docker Desktop, Build Cloud, and Scout are a different product. Forgejo Packages can hold a few images if you already run that forge — Harbor is the dedicated registry.

Will my docker login keep working?

Yes, against the new host. Recreate credentials. Rate limits you hit on hub.docker.com go away because you are pulling from yourself.

Stacks / Backend

Harbor

A container registry you host. Harbor is Apache-2.0 (CNCF) — Docker Hub without the pull and seat meter.

The problem

Docker Hub Pro is $9/user/month billed yearly ($11 monthly); Team is $15/user/month billed yearly ($16 monthly). Personal is free until pull rate limits bite. You wanted images you can push, scan, and pull from CI. Harbor is the CNCF registry: projects, RBAC, and a replication policy. This is not Docker Desktop, Build Cloud, or Scout — those stay on a workstation or another tool.

Agent setup prompt

Replace Docker Hub with Harbor (https://goharbor.io).

- Postgres + Redis + a volume (or S3) for blobs. Bind the registry and the UI. Create one project, one robot account, push one image.
- Point CI at the new registry. Lock anonymous pulls if that is the policy.
- Write AGENT_PROMPT.md. Do not claim Docker Desktop, Build Cloud, or Scout parity — this page is the registry.
