Docker registry

@mario Oh wow, this is awesome. I had no idea one could run a registry this way. I thought one has to make some use of the docker addon! This way is so much simpler and nicer.

I forked the code to https://git.cloudron.io/cloudron/docker-registry-app/ and gave you permissions. It just worked (tm). Do you think you can put in a LICENSE file and keep developing there? It's a holiday for thanksgiving here, but I will look into this soonish.

@mario TIL portus does not implement it's own registry, but simply uses the official one.

Yes, having them separate can have it's benefits. Would need to refresh my knowledge in regards to portus first before I know if I could be of much help.

@girish happy Thanksgiving!

Thanks for the fork, will see what I can do in the coming days

@mehdi said in Docker registry:

Combined with the authProxy of Cloudron6, we could disable the htpasswd auth of the app and since it uses basic auth it should work with the LDAP users !

I gave this a try and this worked great! https://git.cloudron.io/cloudron/docker-registry-app/-/commit/547e3b30b0d9038d9fe73416a7df7b3d32f265ec

Indeed It basically takes advantage of the official registry support for token-auth, giving you a nice UI, permissions, etc.

When you get a moment to check it out, let's talk!

The only problem here is that this would not work for me - we basically only have admins on Cloudron itself, and this would limit Registry access to them alone.

Edit: this is because we do auth via Azure AD/SAML for pretty much everything in the company.

Good point. I forgot to add the optionalSso flag to manifest. With that flag, you can install the app without Cloudron Directory integration (like you do with other apps) and then we can have the default admin/admin setup that you have when LDAP is disabled. Would that work?

[mario]

@girish yes, though there's a bug in your commit So let's make sure we fix that too.

[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
