Docker Build Failed in Github Actions - failed to read dockerfile

问题

我有以下的目录结构：

  1. ├── .github/workflows
  2. │   ├── deploy.yml
  3. ├── app
  4. │   ├── Dockerfile
  5. │   ├── __init__.py
  6. │   ├── main.py
  7. │   ├── requirements.txt
  8.

在deploy.yml中，我有以下内容：

  2. name: TestJobs
  3. on: [push]
  5. jobs:
  7.   build:
  8.     runs-on: ubuntu-latest
  9.     steps:
  10.       - name: Checkout
  11.         uses: actions/checkout@v2
  13.       - name: Set up Docker Buildx
  14.         uses: docker/setup-buildx-action@v1
  16.       - name: Build and push
  17.         uses: docker/build-push-action@v2
  18.         with:
  19.           context: ./app # 甚至尝试过只使用 "app" 而不使用双引号
  20.           file: ./Dockerfile # 甚至尝试过只使用 "Dockerfile" 而不使用双引号
  21.           tags: myimage:latest
  22.           outputs: type=docker,dest=/tmp/myimage.tar
  24.       - name: Upload artifact
  25.         uses: actions/upload-artifact@v2
  26.         with:
  27.           name: myimage
  28.           path: /tmp/myimage.tar

但是，它失败并显示以下错误

> ERROR: failed to solve: failed to read dockerfile: open /tmp/buildkit-mount2199217382/Dockerfile: no such file or directory
Error: buildx failed with: ERROR: failed to solve: failed to read dockerfile: open /tmp/buildkit-mount2199217382/Dockerfile: no such file or directory

注意：如果我将所有内容移动到app/内并将deploy.yml更改为以下内容，一切都能正常工作

  2. . . .
  3.       - name: Build and push
  4.         uses: docker/build-push-action@v2
  5.         with:
  6.           context: .
  7.           file: ./Dockerfile 
  8. . . .

有人能帮我找到这个相对路径的问题吗？

英文:

I have the following Directory structure:

  1. ├── .github/workflows
  2. │   ├── deploy.yml
  3. ├── app
  4. │   ├── Dockerfile
  5. │   ├── __init__.py
  6. │   ├── main.py
  7. │   ├── requirements.txt
  8.

And in the deploy.yml I have the following content:

  2. name: TestJobs
  3. on: [push]
  5. jobs:
  7.   build:
  8.     runs-on: ubuntu-latest
  9.     steps:
  10.       - name: Checkout
  11.         uses: actions/checkout@v2
  13.       - name: Set up Docker Buildx
  14.         uses: docker/setup-buildx-action@v1
  16.       - name: Build and push
  17.         uses: docker/build-push-action@v2
  18.         with:
  19.           context: ./app # even tried with just "app" without double quotation
  20.           file: ./Dockerfile # even tried with just "Dockerfile" without double quotation
  21.           tags: myimage:latest
  22.           outputs: type=docker,dest=/tmp/myimage.tar
  24.       - name: Upload artifact
  25.         uses: actions/upload-artifact@v2
  26.         with:
  27.           name: myimage
  28.           path: /tmp/myimage.tar

But. it fails with the following error

> ERROR: failed to solve: failed to read dockerfile: open /tmp/buildkit-mount2199217382/Dockerfile: no such file or directory
Error: buildx failed with: ERROR: failed to solve: failed to read dockerfile: open /tmp/buildkit-mount2199217382/Dockerfile: no such file or directory

Note: Evrything works fine if I moved all the content inside the app/ to the root directory and change the deploy.yml as below

  2. . . .
  3.       - name: Build and push
  4.         uses: docker/build-push-action@v2
  5.         with:
  6.           context: .
  7.           file: ./Dockerfile 
  8. . . .

Can someone help me find the issue with this relative-path here?

这是我的构建步骤：

  1. - name: 构建并推送 Docker 镜像
  2.   uses: docker/build-push-action@v4
  3.   with:
  4.     context: .
  5.     push: true
  6.     tags: ${{ steps.meta.outputs.tags }}
  7.     labels: ${{ steps.meta.outputs.labels }}

或者

  1. - name: 构建并推送 Docker 镜像
  2.   uses: docker/build-push-action@v4
  3.   with:
  4.     context: .
  5.     file: ./examples/Dockerfile
  6.     push: true
  7.     tags: ${{ steps.meta.outputs.tags }}
  8.     labels: ${{ steps.meta.outputs.labels }}

在第一个示例中，我的 Docker 文件位于我的存储库的根目录。在第二个示例中，我的 Docker 文件位于一个名为 "example"（您的是 "app"）的文件夹中。因此，使用以下方法对您来说应该有效：

  1. - name: 构建并推送 Docker 镜像
  2.   uses: docker/build-push-action@v4
  3.   with:
  4.     context: .
  5.     file: ./app/Dockerfile
  6.     push: true
  7.     tags: myimage:latest
  8.     outputs: type=docker,dest=/tmp/myimage.tar
英文:

Here my build steps:

  1.       - name: Build and push Docker image
  2.         uses: docker/build-push-action@v4
  3.         with:
  4.           context: .
  5.           push: true
  6.           tags: ${{ steps.meta.outputs.tags }}
  7.           labels: ${{ steps.meta.outputs.labels }}

or

  1.       - name: Build and push Docker image
  2.         uses: docker/build-push-action@v4
  3.         with:
  4.           context: .
  5.           file: ./examples/Dockerfile
  6.           push: true
  7.           tags: ${{ steps.meta.outputs.tags }}
  8.           labels: ${{ steps.meta.outputs.labels }}

In example one my docker file is at the root of my repo. In the second example my docker file its in a folder (like you) named example (your is app).so with that approach the following should work for you:

  1.       - name: Build and push Docker image
  2.         uses: docker/build-push-action@v4
  3.         with:
  4.           context: .
  5.           file: ./app/Dockerfile
  6.           push: true
  7.           tags: myimage:latest
  8.           outputs: type=docker,dest=/tmp/myimage.tar

  1. 上下文: app/

我认为这可能会起作用。

英文: 
  1. context: app/

I think that may do it.
