Good fit for Production registries — Harbor bundles vulnerability scanning (Trivy), image signing (Cosign/Notary), RBAC, project quotas.
Weak at Multi-service install; smaller projects find Distribution simpler.

Replaces these SaaS
- Docker Hub · Container image registry
Download the Harbor installer from goharbor.io/docs/2.x/install-config/, edit `harbor.yml` (hostname + storage), run `./install.sh`. Migrate from Docker Hub: `docker login` to your Harbor instance, then loop your Hub images: `docker pull hub.docker.com/myorg/img:tag && docker tag ... && docker push harbor.example.com/proj/img:tag`. Skopeo (`skopeo copy --all docker://hub.docker.com/myorg/img docker://harbor.example.com/proj/img`) handles multi-arch in one shot.
