Docs: Missing all the environment variable options for registry Docker image

[melroy89]

Description

Could somebody please document the environment variable options that are ALL available when using the Docker image registry.

I just noticed: #4151 (comment) .. Maybe you want to explicit document this somewhere instead of a comment.

Feel free to open a PR.

That is a bit of an issue. I don't know all the environment variables. A bit of a chicken egg situation.

[milosgajdos]

I think that's a fair point. Have you seen this documentation section that actually describes how the environment variables overrides work? https://distribution.github.io/distribution/about/configuration/#override-specific-configuration-options

[melroy89]

Yes I know about that. But this issue is again about listing all the available options / environment variables.

That wouldnt scale I'm afraid.
