I use Personal Access Token is "api" https://gitlab.com/profile/personal_access_tokens

because I have 2-factor athorization.

Answer 1

I change:

• Personal Access Token scope: https://gitlab.com/profile/personal_access_tokens to "api" and "read_registry"

• usename in docker login from @user to [email protected]

now it is works.

Seems issue is in "read_registry" scope. And it is strange because "api" also have read access. From Gitlab:

Grants complete read/write access to the API, including all groups and projects, the container registry, and the package registry.
