在操作中使用if语句

Question

我在这里有一个main.yml工作流：

name: Testing

on: 
  push:
    branches:
    - main
jobs:
  upgrade-kubectl:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Install kubectl version
        uses: ./.github/actions/promote-image
        with:
          kubectl: 'latest'

以及我的action.yml元数据文件：

name: "Helm, Kubectl or Devspace installation setup"
description: "Install a specific version of Helm, Kubectl or Devspace. Acceptable values are latest or version strings like 1.15.0"
inputs:
  kubectl:
    description: "Version of Kubectl"
    required: false
  helm:
    description: "Version of Helm"
    required: false
  devspace:
    description: "Version of Devspace"
    required: false
runs:
  using: "composite"
  steps:
    - name: Setting up kubectl
      uses: azure/setup-kubectl@v1
      with:
        version: ${{ inputs.kubectl }}
    - name: Setting up Helm
      uses: azure/setup-helm@v1
      with:
        version: ${{ inputs.helm }}
    - name: Setting up Devspace
      uses: loft-sh/setup-devspace@main
      with:
        version: ${{ inputs.devspace }}

目前，我只是在我的工作流程中提供kubectl版本，但是当操作被触发时，它将运行所有三个步骤。

我如何使它，如果我提供一个版本，它只运行一个步骤，提供两个版本，它分别运行两个步骤，等等。

任何帮助都将不胜感激！

现在看来，复合操作支持条件。。

因此，您可以根据所使用的输入在每个步骤级别添加条件。

在这种情况下，您的action.yml工作流文件如下所示：

name: "Helm, Kubectl or Devspace installation setup"
description: "Install a specific version of Helm, Kubectl or Devspace. Acceptable values are latest or version strings like 1.15.0"
inputs:
  kubectl:
    description: "Version of Kubectl"
    required: false
  helm:
    description: "Version of Helm"
    required: false
  devspace:
    description: "Version of Devspace"
    required: false
runs:
  using: "composite"
  steps:
    - name: Setting up kubectl
      if: ${{ inputs.kubectl != '' }}
      uses: azure/setup-kubectl@v1
      with:
        version: ${{ inputs.kubectl }}
    - name: Setting up Helm
      if: ${{ inputs.helm != '' }}
      uses: azure/setup-helm@v1
      with:
        version: ${{ inputs.helm }}
    - name: Setting up Devspace
      if: ${{ inputs.devspace != '' }}
      uses: loft-sh/setup-devspace@main
      with:
        version: ${{ inputs.devspace }}

请注意，语法：

• if: ${{ inputs.kubectl != '' }}工程
• if: ${{ inputs.kubectl }} != ''没有
