Docker 构建推送操作 "Not a valid object name"；输出 repo 的所有分支和标签

Question

当运行我们的 docker 构建在 GitHub 操作工作流中时，docker/build-push-action@v2 一直在下面输出此错误。这是在运行我们的 Dockerfile 中的任何命令之前：

Run docker/build-push-action@v2
  with:
    file: packages/api/Dockerfile
    tags: us.gcr.io/org-blahblah-shared/project-api:v7.9914
    push: true
    cache-from: type=gha
    cache-to: type=gha,mode=max
    load: false
    no-cache: false
    pull: false
    github-token: ***
  env:
    MAJOR_VERSION: v7
    DOCKER_REGISTRY: us.gcr.io
    GCP_PROJECT_ID: org-blahblah-shared
    TAG: v7.9914

#1 6.363  * [new tag]             v2
#1 6.363  * [new tag]             ...

这输出了大约 3000 行无用的输出，并且似乎是一些错误配置。我怎样才能解决这个根本问题，或者至少控制输出？

它似乎与 docker buildx build 命令的最后一部分有关：--push https://github.com/org/project.git#abc123，但这似乎不受我们任何配置的直接控制。

结果是 build-push-action runs in a "GitHub" context by default。至少，这意味着作为 pre-Dockerfile 命令的一部分拉下您的存储库。

您可以使用以下方法将其更改为“文件”上下文：

      - name: Build and push
        uses: docker/build-push-action@v2
        with:
          context: .
          push: true
          tags: user/app:latest

由于我们之前作为结帐操作的一部分删除了存储库，因此它是多余的。
