in my situation , i using Registry:2 from docker Hub to make this is Private Docker Registry for my own and expose to example URL : registry.docker:5000.
Beside that , i used Gitlab CI ( gitlab-ci.yml) to run CI to build an image to ship code inside them.
It’s okay when build image but when push custom image to private docker registry below , GitlabCI is always FAIL.
How Gitlab work with Docker private registry?
i just test login private registry in Gitlab-CI:
- docker login $DOCKER_HOST -u myuser -p $pwd
