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

问题

我创建了一个 Flask 应用并使用 Docker 部署它，我在 Mac 上手动部署并成功了，以下是我的 Dockerfile 脚本：

  1. # 从 python 镜像开始
  2. FROM python:3.8-alpine
  4. # 将 requirements 文件复制到镜像中
  5. COPY ./requirements.txt /app/requirements.txt
  7. # 切换工作目录
  8. WORKDIR /app
  10. # 安装 requirements 文件中指定的依赖和包
  11. RUN pip3 install -r requirements.txt
  13. # 将本地文件的所有内容复制到镜像中
  14. COPY . /app
  16. EXPOSE 1201
  18. # 执行 Flask 应用
  19. CMD ["python3", "run.py"]

然后我尝试使用 GitHub Actions 进行自动部署，以下是我的 YML 脚本：

  1. name: Docker Image CI
  3. on:
  4.   push:
  5.     branches: ["new-feature"]
  6.   pull_request:
  7.     branches: ["new-feature"]
  8.    
  10. jobs:
  12.   build:
  13.     runs-on: macos-latest
  15.     steps:
  17.     - name: 安装 docker colima
  18.       run:  |
  19.           brew install docker
  20.           colima start          
  22.     - uses: actions/checkout@v3
  23.     - name: 构建 Docker 镜像
  24.       run: docker build --tag my_image2 .
  25.     
  26.     - name: 运行 docker 镜像
  27.       run: docker run -d -p 1201:1201 my_image2

我认为一切都正常工作，镜像已成功构建：

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

然后我检查我的镜像不存在，无论在 Docker 还是在 colima 中。

所以问题是什么，你们能给我一个解决方案吗？谢谢！

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

  1. # start by pulling the python image
  2. FROM python:3.8-alpine
  4. # copy the requirements file into the image
  5. COPY ./requirements.txt /app/requirements.txt
  7. # switch working directory
  8. WORKDIR /app
  10. # install the dependencies and packages in the requirements file
  11. RUN pip3 install -r requirements.txt
  13. # copy every content from the local file to the image
  14. COPY . /app
  16. EXPOSE 1201
  18. # execute the Flask app
  19. CMD ["python3", "run.py"]

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

  1. name: Docker Image CI
  3. on:
  4.   push:
  5.     branches: [ "new-feature" ]
  6.   pull_request:
  7.     branches: [ "new-feature" ]
  8.    
  10. jobs:
  12.   build:
  13.     runs-on: macos-latest
  15.     steps:
  17.     - name: instal docker colima
  18.       run:  |
  19.           brew install docker
  20.           colima start
  22.     - uses: actions/checkout@v3
  23.     - name: Build the Docker image
  24.       run: docker build --tag my_image2 .
  25.     
  26.     - name: run docker image
  27.       run: docker run -d -p 1201:1201 my_image2

and i think all working well, images built successfully :

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

Docker构建成功，但在docker images中未显示构建的镜像。

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

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

Docker 最近将构建后端更改为默认使用 buildx，这可能会导致一些问题，具体取决于您使用的 Docker 版本以及安装方式。为了避免依赖于平台的代码，可以使用预定义的操作：

请查看官方 GH-Action Docker Build 文档

  1. name: Docker Image CI
  3. on:
  4.   push:
  5.     branches: ["new-feature"]
  6.   pull_request:

  9. jobs:
  10.   build:

  27.           tags: my-image
  29.       - name: 运行 Docker 镜像

  31.           docker image ls
  32.           docker run -d -p 1201:1201 my-image

当您想在其他计算机上使用该镜像时，您需要将其上传到 DockerHub 或 GitHub 容器注册表之类的注册表：

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
