GitHub Build容器映像出现错误

问题描述

我正在通过培训GitHub Actions: Publish to GitHub Packages来学习CD。

所以我创建了一个Dockerfile，但是无法构建。我不明白为什么会发生此错误。你怎么解决呢？

到目前为止，我仅使用该机器人提供的源代码，因此很难想到一个简单的错字。

这是错误消息的摘录。

Error: exit status 125

解决方法

您的.github/workflows/cd-workflow.yml提到：

    - name: Build container image
      uses: docker/build-push-action@v1
      with:
        username: ${{github.actor}}
        password: ${{secrets.GITHUB_TOKEN}}
        registry: docker.pkg.github.com
        repository: CreatorOfWhileStudying/github-actions-for-packages/tic-tac-toe
        tag_with_sha: true

存储库部分与docker构建不兼容，如logs for that action所示：

该错误来自GitHub Action docker/build-push-action，就像issue 37中一样。
尝试使用docker/build-push-action@v2。
