在 Github Actions 中获取当前推送的标签 [英] Get the current pushed tag in Github Actions

问题描述

有没有办法访问在 Github Action 中推送的当前标签?在 CircleCI 中，您可以使用 $CIRCLE_TAG 变量访问此值.

Is there a way to access the current tag that has been pushed in a Github Action? In CircleCI you can access this value with the $CIRCLE_TAG variable.

我的工作流程 yaml 被这样的标签触发:

My Workflow yaml is being triggered by a tag like so:

on:
  push:
    tags:
      - 'v*.*.*'

我想稍后在工作流程中使用该版本号作为文件路径.

And I want to use that version number as a file path later on in the workflow.

推荐答案

据我所知没有标签变量.但是，它可以从包含签出 ref 的 GITHUB_REF 中提取，例如refs/tags/v1.2.3

As far as I know there is no tag variable. However, it can be extracted from GITHUB_REF which contains the checked out ref, e.g. refs/tags/v1.2.3

试试这个工作流程.它使用提取的版本创建一个新的环境变量，您可以在以后的步骤中使用它.

Try this workflow. It creates a new environment variable with the extracted version that you can use in later steps.

on:
  push:
    tags:
      - 'v*.*.*'
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Set env
        run: echo "RELEASE_VERSION=${GITHUB_REF#refs/*/}" >> $GITHUB_ENV
      - name: Test
        run: |
          echo $RELEASE_VERSION
          echo ${{ env.RELEASE_VERSION }}

或者，使用 set-output:

on:
  push:
    tags:
      - 'v*.*.*'
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Set output
        id: vars
        run: echo ::set-output name=tag::${GITHUB_REF#refs/*/}
      - name: Check output
        env:
          RELEASE_VERSION: ${{ steps.vars.outputs.tag }}
        run: |
          echo $RELEASE_VERSION
          echo ${{ steps.vars.outputs.tag }}
