I'm trying to push for the first time to a gitlab project container registry. I am not a gitlab administrator so I can't change global settings. But as far as my project is concerned I've made sure that I have a personal access token created for the project.
When I try to run my pipeline, it fails with a 404 error. I've recreated the steps just on the commandline to simplify things. here's what the output looks like:

PS /Users/me/src/pipelinetests> docker login -u widgetsProjectAccessToken -p asdf mygitserver.org/myusername/pipelinetests

What I've Done so far

I've made sure that my project visibility and the settings are correct:

enter image description here

I've also created the personal access token - which the successful login proves.

Questions

In googling, it seems that some people found their container registry wasn't actually set up properly. I'm not sure how to test that if I'm not a global admin.
So my first question is do you know of any other way I can test to make sure that it's a config issue?

If we assume it's actually set up correctly, could it just be that I haven't specified the correct port in my push command? Like if the admin chose a non standard port, could that be the issue?

Are there other trees I should be barking up?

EDIT 1

These are the options under Packages & Registries

It looks to me like you're not pushing to the right port.

When you go to the project space, and then go to your container registry /container_registry (or click under Packages & RegistriesContainer Registry

Menus hove

Or, like this if you prefer to click on Packages & Registries

Menu click

On this page you should see a bunch of links, one of them should have something like this,

docker push domain:5050/myusername/pipelinetests

You want to be sure you're including that :5050. That's the defualt port for the GitLab Container Registry. It looks like from that error, that you're targeting the actual project page.

  • ok so under package & registries, i don't even have Container Registry. I only have package & infrastructure as options. I guess that's the smoking gun? I assumed it would go under package registry. Please see my EDIT 1 for new screenshot

    @dot that would be a smoking gun, imho yes. I put a copy of the menu above. Commented Apr 21, 2022 at 17:24
