我正在用Github动作构建Docker图像,并想用分支名称标记图像。
我找到了GITHUB_REF变量,但它导致了refs/heads/feature-branch-1,我只需要feature-branch-1。

下面是一个适用于push和pull_request事件的完整工作流
name: whichBranch
on: [pull_request, push]
jobs:
which_branch:
runs-on: ubuntu-latest
steps:
- name: Extract branch name on push
if: github.event_name != 'pull_request'
shell: bash
run: echo "::set-env name=BRANCH_NAME::$(echo ${GITHUB_REF#refs/heads/})"
id: extract_branch
- name: Extract branch name on pull request
if: github.event_name == 'pull_request'
run: echo "::set-env name=BRANCH_NAME::$(echo ${GITHUB_HEAD_REF})"
- name: Print branch name
run: echo 'The branch name is' $BRANCH_NAME

我只是在GitHub Actions中使用bash脚本做了一个简单的测试:
#!/bin/bash
echo Reserved for REPO_NAME=${GITHUB_REPOSITORY##*/}
echo GITHUB_REF=${GITHUB_REF}
echo EXTRACT_GITHUB_REF=${GITHUB_REF##*/}
echo EXTRACT_GITHUB_REF_HEADS=$(echo ${GITHUB_REF#refs/heads/})
cd $REPO_NAME
git checkout ${GITHUB_REF##*/}
git checkout $(echo ${GITHUB_REF#refs/heads/})
以下是输出的截图:
因此${GITHUB_REF##*/}和$(echo ${GITHUB_REF#refs/heads/})都是正确的
如何在Github行动中获得当前的分支?
假设${{github。Ref}}类似于refs/heads/mybranch,你可以使用以下方法提取分支名称:
steps:
- name: Prints the current branch name
run: echo "${GITHUB_BRANCH##*/}"
env:
GITHUB_BRANCH: ${{ github.ref }}
如果你的分支包含斜杠(比如feature/foo),使用下面的语法:
steps:
- name: Prints the current branch name
run: echo "${GITHUB_REF#refs/heads/}"
致谢:@rmunn评论
或者使用已接受答案的方法,这里是更短的版本(lint友好):
steps:
- name: Get the current branch name
shell: bash
run: echo "::set-output name=branch::${GITHUB_REF#refs/heads/}"
id: myref
然后在其他步骤中引用${{steps.myref.outputs.branch}}。
注:
上述方法仅适用于基于unix的映像(Linux和macOS)。 对于文档,请阅读:GitHub Actions的上下文和表达式语法。
为了获得delete事件上的ref名称,我最终使用了sed。
on:
delete:
...
steps:
- name: Do something
shell: bash
run: |
refname=$(sed -e s:refs/heads/::g -e s:/:-:g <<< ${{ github.event.ref }})
剪掉指针/头/并将斜杠转换为破折号,例如。引用/heads/feature/somefeature到feature-somefeature
现在$ {{github。Ref}}是获取分支名称的正确方法。 请记住${{github。Ref}}有refs/heads/..前缀
获取当前分支很简单,下面的代码适用于我和
github.ref_name
是用于获取分支名称的预定义变量吗
jobs:
main-branch-build:
if: github.ref_name == 'main'
runs-on: ubuntu-latest
steps:
- name: Check out code
uses: actions/checkout@v3
feature-branch-build:
if: github.ref_name != 'main'
runs-on: ubuntu-latest
steps:
- name: Check out code
uses: actions/checkout@v3
