Self-hosted Docker Runner using custom images times out or no such image found (404)

[Casey Local]

I have setup the Docker Runner on a Redhat 8 instance. When executing a simple pipeline, it eventually appears to time out or return a no images found message. Is the following correct? Do I need to define the location of the images, all of which are in Docker Hub?

I'm also seeing the following message on occasions during step1:

"Timed out after 5 minutes waiting for 2 remaining services to be ready"

definitions:

  services:

    docker-php74:

      type: docker 

      image: php:7.4.33-fpm

    docker-node-erbium:

      type: docker 

      image: node:erbium

pipelines:

  default:

    - step:

        name: Step 1

        runs-on: 

          - self.hosted

          - linux

        services:

          - docker-php74

        script:

          - docker info

    - step:

          name: Step 2

          services:

            - docker-node-erbium

          runs-on: 

            - self.hosted

            - linux

          script:

            - docker info

            - echo "This step will use the defult docker service defenition.";

Hi @Casey Local and welcome to the community.

You don't need to define the location for Docker Hub images. I suspect that the Docker images you are using may not be dind images, resulting in this error.

Can you try using the docker:dind image instead and see if your build succeeds?

I am also unsure why you are trying to use php and node images in the Docker service. If you want to use these images as a build container, you can use them in the definition of each step instead. You could try e.g. something as follows:

definitions:
  services:
    docker:
      type: docker 
      image: docker:dind

pipelines:
  default:
    - step:
        name: Step 1
        image: php:7.4.33-fpm
        runs-on: 
          - self.hosted
          - linux
        services:
          - docker
        script:
          - docker --version
    - step:
        name: Step 2
        image: node:erbium
        runs-on: 
          - self.hosted
          - linux
        services:
          - docker
        script:
          - docker info

Kind regards,
