I am trying to run the following docker-compose yml in the github workflow, but I get the error of

Error response from daemon: No such image: ghcr.io/whats/app/backend/222243434353535353f

The error happens at the "Tag images" point below

The docker Ci file is

env:
    WEB_IMAGE_BASE: ghcr.io/$(echo $GITHUB_REPOSITORY | tr '[:upper:]' '[:lower:]')/backend
    WEB_IMAGE: ghcr.io/$(echo $GITHUB_REPOSITORY | tr '[:upper:]' '[:lower:]')/backend:$( echo $GITHUB_SHA )

jobs:
  build:
    name: Build Docker Images
    runs-on: ubuntu-latest
    steps:
      - name: Prepare images
        run: |
          echo "WEB_IMAGE=$(echo ${{env.WEB_IMAGE}} )" >> $GITHUB_ENV
          echo "WEB_IMAGE_BASE=$(echo ${{env.WEB_IMAGE_BASE}} )" >> $GITHUB_ENV

      - name: Build images
        run: |
          docker-compose -f ci.yml build backend

      - name: Tag images
        run: |
          docker tag ${{ env.WEB_IMAGE }}  ${{ env.WEB_IMAGE_BASE }}:latest

The ci.yml is

 ​version​: ​"​3.9​" 
  
 ​services​: 
 ​  ​backend​: 
 ​    ​image​: ​backend_prod
 

​

What am I doing wrong or please indicate how to fix this?

CodePudding user response：

You are trying to tag and image using as a source an image that doesn't exist.

The image ghcr.io/whats/app/backend/222243434353535353f wasn't created in any place.

You need to use as a source in tag command the built image result of docker-compose build.

Since you specify in your compose the image: backend_prod your image will be named by that.

Try to change the image in your docker compose to something like:

version: "3.9"
services:
  backend:
    build:
      context: .
      dockerfile: ./backend/dockerfile
    image: backend_prod:local

And change your ci file:

- name: Tag images
    run: |
      docker tag backend_prod:local ${{ env.WEB_IMAGE_BASE }}:latest
