Publishing containers to GitHub might be free but you have to login to GitHub to download the containers from free accounts, significantly hampering end-user usability compared to Docker Hub, particularly if 2FA authentication is enabled on a GitHub account. As mentioned elsewhere Quay.io might be another alternative.

We (the GitHub Packages team where I work) are working on a fix for this and a number of issues with the current docker service. You can join the beta too, details here https://github.com/containerd/containerd/issues/3291#issueco...

You don't need to register an SSH key to download a public repo I thought

Not an SSH key, but you do need an access token:

...but not to download. You can clone a repo and download release artifacts without a PAT. That's only necessary for interacting with the API for actions that need authentication, which would be anything involving mutating a repository.

Yes, you need one to download. Note that you'll get an auth prompt for this Registry API URL:

https://docker.pkg.github.com/v2/test/test/test/tags/list

> "code": "UNAUTHORIZED", "message": "GitHub Docker Registry needs login"

Using the GitHub Docker Registry requires auth, even just for downloads.

GitHub Packages is different from GitHub Releases (and their artifacts) or cloning repos.

> You need an access token to publish, install, and delete packages in GitHub Packages.

Yes, you do.

GitHub access tokens are a bit of a nightmare since you can't limit the permissions for a token. Only workaround I've found is to create another GitHub user for an access token and restrict that user's access.
