GitHub Action Error: Docker pull failed with exit code 1-CodePudding

I'm trying to run my npm build inside the docker container using our private docker image with GitHub actions.

My Workflow yaml file as follows,

jobs:
  build:
    runs-on: Linux-self-hosted  # This is our self hosted linux runner system.
    container:
      image: ubuntu-20.04-lts:latest  # This is our private docker image.

    steps:
    - name: Checkout Repository
      uses: actions/checkout@v2
      
    - name: Npm Build
      run: npm install

    - name: Build Package
      run: vsce package

GitHub Action Error:-

Starting job container /usr/bin/docker pull ubuntu-20.04-lts:latest Error response from daemon: pull access denied for ubuntu-20.04-lts, repository does not exist or may require 'docker login': denied: requested access to the resource is denied Warning: Docker pull failed with exit code 1, back off 4.74 seconds before retry.

i have this ubuntu-20.04-lts:latest private docker image on my host system locally. Still it fails with above error during action build.

It looks trying to connect docker hub. How do i fix this to use our local private image?

CodePudding user response：

You'll have to push your image to your private registry. Once it is there, you can configure the credentials for your private registry as described in the docs:

container:
  image: ghcr.io/owner/image
  credentials:
     username: ${{ github.actor }}
     password: ${{ secrets.ghcr_token }}
