GitHub 动作：如何在步骤中使用矩阵值

Question

我在 GitHub 操作中有一个简单的管道。我正在尝试在其中构建 Docker 图像并将其发布到 Docker Hub。我还想为不同的平台（阅读：操作系统）构建图像，因此我使用 strategy.matrix。这是目前的样子：

name: Build and Publish Docker image(s)

jobs:
  publish:
    runs-on: ubuntu-latest
    steps:
      - name: Check out repository
        uses: actions/checkout@v2
      - name: Log in to Docker Hub
        uses: docker/login-action@v1
        with:
          password: ${{ secrets.DOCKERHUB_TOKEN }}
          registry: docker.io
          username: ${{ secrets.DOCKERHUB_USERNAME }}
      - name: Build and push
        uses: docker/build-push-action@v2
        env:
          platform: ${{ matrix.platforms }}
        with:
          context: ./${platform}/
          push: true
          tags: oscarotero/lume:1.3.0-${platform} # TODO: Parameterize version once this is finally working
    strategy:
      matrix:
        platforms:
          - alpine
          - debian

on:
  push:
    branches:
      - main

这是 currently failing because it doesn't recognize platform when running the Build and push step. I have a similar one，它适用于这种方法。

在GitHub Actions 方面有更多知识的人可以在这里提供一些线索吗？我能想到的是 docker/build-push-action@v2 不支持那个，但在那种情况下，我该如何解决这个问题？

删除环境变量并使用matrix值直接解决了问题：

jobs:
  publish:
    runs-on: ubuntu-latest
    steps:
      - name: Check out repository
        uses: actions/checkout@v2
      - name: Log in to Docker Hub
        uses: docker/login-action@v1
        with:
          password: ${{ secrets.DOCKERHUB_TOKEN }}
          registry: docker.io
          username: ${{ secrets.DOCKERHUB_USERNAME }}
      - name: Build and push
        uses: docker/build-push-action@v2
        with:
          context: ./${{ matrix.platform }}/
          push: true
          tags: oscarotero/lume:1.3.0-${{ matrix.platform }}
    strategy:
      matrix:
        platform:
          - alpine
          - debian
