Pull Docker images from GitHub Container Registry in preference to DockerHub

[bestbeforetoday]

Current Status

DockerHub has imposed more restrictive limits on image pulls, and has also raised costs for business users. This makes DockerHub a less desirable default platform from which to pull Docker images during Fabric installation. GitHub Container Registry (GHCR) remains freely available, and recent Fabric releases publish Docker images there in addition to DockerHub.

Expected

Use GHCR to pull Docker images.

Solution

Where Docker image versions are available from GHCR, the Fabric install script should pull from there. For versions that are not available from GHCR, the install script should fall back to DockerHub.

The install script should continue to honour the Docker registry override using environment variables with no change in this behaviour.

Please let us know if you plan to work on this.
