gitlab project registry - docker push fails with invalid reference format error message

[jeanid]

I have create a personal access token for my project. in my gitlab-ci.yml I'm trying to create a docker image and then save it in my project's repository.

I'm able to login - I see an explicit message saying Login Succeeded. Then it builds the image but when trying to push is where I see this error:

I do see the Packages & Registries option in my project - which I guess indicates its enabled? But the list of packages is empty, of course. Any suggestions would be appreciated.

EDIT 1

I've tried changing the permissions / visibility on the project from private to Internal - everyone with access should now be able to do mostly everything on this test repo. But it didn't fix the issue.

Also in case it's related ... The URL for the project in gitlab is:

 https://mygitserver.org/JJ/pipelinetests

aka. I have Uppercase in my path. But the docker login command never complains about the lower/uppercase. I've tested with both.
it always says it was successful:

Executing "step_script" stage of the job script
$ docker login -u myPersonalAccessTokenUserName -p asdfasdfQn  https://mygitserver.org/jj/pipelinetests
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Login Succeeded
$ docker build -t widgetsimage .
#1 [internal] load build definition from Dockerfile

EDIT 2

I've also tried to use the url that I see when i navigate to the packages in the Gitlab GUI for the docker push command, like so:

https://mygitserver.org/jj/pipelinetests/-/packages/widgetimage

But still no dice.

EDIT 3

So I tried to change my code like this:

- docker login -u myPersonalAccessTokenUserName -p asdfasdfQn mygitserver.org
- docker build -t mygitserver.org/jj/pipelinetests/widgetsimage .
- docker push mygitserver.org/jj/pipelinetests/widgetsimage

But I'm basically getting a 404 / permissions error.

I googled around a bit and I guess it's still possible that the registry option in general for Gitlab needs to be configured. Is this true? Like I need to assign a specific port for the registry? wondering how I can check? I'm not a gitlab admin. I don't have access to the server config. But wondering if there's anything I can try / test that would conclusively prove that the registry hasn't been set up globally?

An image reference in docker doesn't contain the schema, so there's no https://. For a registry login, you login to the server only, not to the repository. And when building, the tag either needs to include the full image reference you want to later push, or you need to retag the image with docker tag to have the name you want to push. So your steps should be:

    - docker login -u myPersonalAccessTokenUserName -p asdfasdfQn mygitserver.org
    - docker build -t mygitserver.org/jj/pipelinetests/widgetsimage .
    - docker push mygitserver.org/jj/pipelinetests/widgetsimage
