I have a .gitlab-ci.yml very near if not identical to the informations provided by GitLab Container Registry | GitLab
build:
image: docker:19.03.12
stage: build
services:
- docker:19.03.12-dind
variables:
IMAGE_TAG: $CI_REGISTRY_IMAGE:$CI_COMMIT_REF_SLUG
script:
- docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
- docker build -f .docker/backend/Dockerfile -t $IMAGE_TAG .
- docker push $IMAGE_TAG
If I push a change everything seems fine: A pipeline is started that succeed: 1 job for develop in 2 minutes and 23 seconds
However if other developers are pushing to the same branch the pipeline fails with 0 jobs for develop.
If I now manually trigger a pipeline run from the webinterface, select develop as branch (no variables provided) then his commit also can be built perfectly fine.
Maybe I misconfigured something I don’t know of?
I tried to google for that but it seems I am missing the right direction to search for.
