Recently I came a cross with GitLab CI problem when I wanted to login to to the registry.
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Solution itself is easy as just copy and configure as your need.
image: docker:stable-git
services:
- docker:dind
stages:
- build
before_script:
- echo $CI_BUILD_TOKEN | docker login --username=gitlab-ci-token --password-stdin registry.gitlab.com
after_script:
- docker logout registry.gitlab.com
build:docker:
stage: build
script:
- docker build -t registry.gitlab.com/groupname/reponame/master:docker .
- docker push registry.gitlab.com/groupname/reponame/master:docker
If you Google it this problem, and you can see many solved problem which didn’t work with GitLab CI. I found this solution than I tried and everything works as expected.
