Docker registry

[girish]

@mario Ha ha, possibly. I only hacked it up quickly and checked if proxyAuth code in 6.0 will work before I make the release.

[mario]

@girish enjoy your holiday and let me know when you're back around next week so we can take this further

[mehdi]

@girish great ! I was 90% sure it would work, I'm glad I got it right

About interfaces, Portus indeed looks really great. However, I really don't see how it would work as a separate app. I really think it makes sense to bundle them together.

[girish]

Is Portus still developed? It seems it has seen no commits since Mar 25 2020?

I am both excited about this and confused about where it is at. My endgame is using GitLab to manage containers, but I need to point it at a registry. Would this ultimately work? And is there a way to have auth go through gitlab for this?

[mario]

@atrilahiji it's currently working as a stand-alone registry via basic auth powered by htpasswd file. It'll also support Cloudron SSO shortly, after that I'll work on making it work with GitLab.

[robi]

@mario how's it going?

[mario]

@robi I have managed to integrate the registry with GitLab.

@girish where are we at with making proper MR for AuthProxy + making SSO optional? Then I can document GitLab integration, you can write some tests and off we go!

[girish]

@mario Fantastic news. So, all we need is docs to make it work with GitLab registry or does it need any packages changes to gitlab app or docker registry app ?

[mario]

@girish doesn't seem like it'll need package changes, documentation will be enough.

[mario]

I take that back, I did add some package changes. Had no time to test, but things seem to be working ok from the initial glimpse at it:

https://git.cloudron.io/cloudron/docker-registry-app/-/merge_requests/1

Please test and report back @girish and others

[robi]

Might be useful to add auto deletion of old images:

@robi GitLab does that for me Maybe a separate app?

[girish]

@mario Just looking into this now.

Wondering, what is the best way forward. The app has no UI, but can have a login screen (via proxyAuth). So, when they login, they see a blank screen. Not ideal. Does it make sense to bundle any of the docker uis like https://github.com/Joxit/docker-registry-ui/ ? Seems quite easy to do. I can look into it.

[robi]

@mario that's great, but the standalone private registry app that's coming may need it and as @girish pointed out a simple UI.

Also not everyone is interested in the ruby laden GitLab and all it's complexity.

[mario]

@girish depends on what the community needs. I'm more than happy to have a separate registry + other things as separate apps for those who need it.

If I needed to pick the best registry solution with UI and everything else that's well maintained and suitable for Cloudron, I'd probably look at Quay which supports LDAP auth.

I am 100% in favor of bundling a simple UI together with the registry. Even if one does not need it and wants to use the gitlab UI, there's basically nothing to lose besides a few kB of storage ^^

[jimcavoli]

Yeah, Quay and Harbor are definitely the big players in this space. Very similar products - harbor is CNCF graduated and Quay is upstream for the corresponding Red Hat product. Either (or both) would be good UI adds.

[girish]

Last I checked harbor was impractical to package (as in way too much effort, it's really geared for the k8s crowd). Quay is a good option, but let me get this basic docker registry out first, I am almost there.

[mario]

@jimcavoli Quay afaik implements the protocol as well, so no need for registry separately.
