Docker built successfully but no built image show up in the docker images


I was create flask-app and deploy it using docker, i deploy manually in mac and success, this is my Dockerfile script :

# start by pulling the python image
FROM python:3.8-alpine

# copy the requirements file into the image
COPY ./requirements.txt /app/requirements.txt

# switch working directory
WORKDIR /app

# install the dependencies and packages in the requirements file
RUN pip3 install -r requirements.txt

# copy every content from the local file to the image
COPY . /app

EXPOSE 1201

# execute the Flask app
CMD ["python3", "run.py"]

and i try to automatic deploy using github actions, and it is my YML script :

name: Docker Image CI

on:
  push:
    branches: [ "new-feature" ]
  pull_request:
    branches: [ "new-feature" ]
   

jobs:

  build:
    runs-on: macos-latest

    steps:

    - name: instal docker colima
      run:  |
          brew install docker
          colima start

    - uses: actions/checkout@v3
    - name: Build the Docker image
      run: docker build --tag my_image2 .
    
    - name: run docker image
      run: docker run -d -p 1201:1201 my_image2

and i think all working well, images built successfully :

Step 7/7 : CMD ["python3", "run.py"]
 ---> Running in f0144a0c80f6
Removing intermediate container f0144a0c80f6
 ---> d068026c42b0
Successfully built d068026c42b0
Successfully tagged my_image2:latest

images built successfully

and then i check my image not exist, in docker even in colima

images not exist

So what the problem, and you guys can give me a solution ? thank you


Solution

  • Docker recently changed their build backend to use buildx as default. It may cause some issues depending on the version of docker you use and how you install it. To avoid plattform dependent code use predefined actions:

    See the official GH-Action Docker Build Docs

    name: Docker Image CI
    
    on:
      push:
        branches: [ "new-feature" ]
      pull_request:
        branches: [ "new-feature" ]
       
    jobs:
      build:
        runs-on: macos-latest
        steps:
          - name: Checkout code
            uses: actions/checkout@v3
    
          - name: Set up QEMU
            uses: docker/setup-qemu-action@v2
    
          - name: Set up Docker Buildx
            uses: docker/setup-buildx-action@v2
    
          - name: Build and push
            uses: docker/build-push-action@v4.1.1
            with:
              push: false
              load: true
              tags: my-image
    
          - name: run docker image
            run: |
              docker image ls
              docker run -d -p 1201:1201 my-image
    
    

    When you want to use the image on other machines you have to upload it to a registry like DockerHub or GitHub Container Registry:
