Docker is not able to use local image when runs from gitlab pipeline

Trying to set up gitlab pipeline with docker-in-docker. I've created docker image from Dockerfile. It exists locally. When I run it manually from cli docker run -it docker-c sh, it is runs correctly.

When it is done by the pipeline it seems to ignore that there's existing docker-c image, and looks for it in the dockerhub

job output:

Solution

  • you haven't creted docker image regitsry in your gitlab, gitlab pipeline won't be able to pull docker image from your local machine. you need to push it to the conatiner registry and pull it from there to be used in pipelines.you need to first:

    1. create a container registry in your gitlab
    2. build your image locally , tag it and push it to registry
    3. set up credentials to access the registry in pipeline
    4. pull your image to be used in you CI pipeline from that registry

    we can clearly see in the error saying that ther repository does not exsist meaning you havent created registry to host your docker image.

    WARNING: Failed to pull image with policy "always": Error response from daemon: pull access denied for docker-c, repository does not exist or may require 'docker login': denied: requested access to the resource is denied (manager.go:251:3s) ERROR: Job failed: failed to pull image "docker-c:latest" with specified policies [always]: Error response from daemon: pull access denied for docker-c, repository does not exist or may require 'docker login': denied: requested access to the resource is denied (manager.go:251:3s)

    here is an article which you can refer and figure out what you are doing wrong: https://gitlab-docs.creationline.com/ee/user/packages/container_registry/build_and_push_images.html
