First log in to GitLab’s Container Registry using your GitLab username and password. If you have 2FA enabled you need to use a personal access token:

docker login gitlab.espe.edu.ec:5555

You can also use a deploy token for read-only access to the registry images.

Once you log in, you’re free to create and upload a container image using the common build and push commands

docker build -t gitlab.espe.edu.ec:5555/jamolina13/backend-v1-jasperreport .
docker push gitlab.espe.edu.ec:5555/jamolina13/backend-v1-jasperreport

Use different image names

GitLab supports up to 3 levels of image names. The following examples of images are valid for your project:

gitlab.espe.edu.ec:5555/jamolina13/backend-v1-jasperreport:tag
gitlab.espe.edu.ec:5555/jamolina13/backend-v1-jasperreport/optional-image-name:tag
gitlab.espe.edu.ec:5555/jamolina13/backend-v1-jasperreport/optional-name/optional-image-name:tag
