GitHub (ghcr.io)
GitHub Container Registry. Two hosts, both required.
| Host | Ports | Purpose | |
|---|---|---|---|
| ghcr.io | 443 | Registry API and token authentication | required |
| pkg-containers.githubusercontent.com | 443 | Blob storage (redirect target for layer downloads) | required |
Notes
Auth tokens come from ghcr.io itself, but layer downloads redirect to pkg-containers.githubusercontent.com. With only ghcr.io open, pulls authenticate fine and then stall on the first layer.
