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。

当前回答
如果你使用的是V2的actions/checkout,那么你总是可以运行git branch——show-current来获取当前签出的分支的名称。
其他回答
你可以使用https://github.com/rlespinasse/github-slug-action
# Just add this =>
- name: Inject slug/short variables
uses: rlespinasse/github-slug-action@v3.x
# And you get this =>
- name: Print slug/short variables
run: |
echo "Slug variables"
echo " - ${{ env.GITHUB_REF_SLUG }}"
echo " - ${{ env.GITHUB_HEAD_REF_SLUG }}"
echo " - ${{ env.GITHUB_BASE_REF_SLUG }}"
echo " - ${{ env.GITHUB_REPOSITORY_SLUG }}"
# output e.g. : master feat-new-feature v1.0.0 product-1.0.0-rc.2 new-awesome-product
echo "Slug URL variables"
echo " - ${{ env.GITHUB_REF_SLUG_URL }}"
echo " - ${{ env.GITHUB_HEAD_REF_SLUG_URL }}"
echo " - ${{ env.GITHUB_BASE_REF_SLUG_URL }}"
echo " - ${{ env.GITHUB_REPOSITORY_SLUG_URL }}"
# output e.g. : master feat-new-feature v1-0-0 product-1-0-0-rc-2 new-awesome-product
echo "Short SHA variables"
echo " - ${{ env.GITHUB_SHA_SHORT }}"
# output e.g. : ffac537e
在这里重复一下,以便更好地看到其他人在之前的回复中作为简单注释写的内容:
https://docs.github.com/en/actions/learn-github-actions/environment-variables
只在这个环境变量中暴露了pull请求的分支名称:
仅为拉请求事件设置。总行的名称。
在GitHub动作中,对应的上下文键是:
github.head_ref
我相信GITHUB_REF是唯一包含分支名称的环境变量。
你可以从字符串的其余部分提取分支名称,如下所示:
${GITHUB_REF##*/}
例子:
$ GITHUB_REF=refs/heads/feature-branch-1
$ echo ${GITHUB_REF##*/}
feature-branch-1
更新:添加了一个完整的工作流示例。

有关参数展开语法的更多信息,请参阅这个答案。
作为参考,GitHub Actions的虚拟环境页面列出了执行环境中可用的所有环境变量。
GitHub Action FranzDiebold/ GitHub -env- vals - Action公开了几个有用的环境变量,例如当前分支名称及其slug值。我为这个用例做了这个操作。
使用
steps:
- uses: FranzDiebold/github-env-vars-action@v1.2.0
- name: Print environment variables
run: |
echo "GITHUB_REPOSITORY_SLUG=$GITHUB_REPOSITORY_SLUG"
echo "GITHUB_REPOSITORY_OWNER=$GITHUB_REPOSITORY_OWNER"
echo "GITHUB_REPOSITORY_OWNER_SLUG=$GITHUB_REPOSITORY_OWNER_SLUG"
echo "GITHUB_REPOSITORY_NAME=$GITHUB_REPOSITORY_NAME"
echo "GITHUB_REPOSITORY_NAME_SLUG=$GITHUB_REPOSITORY_NAME_SLUG"
echo "GITHUB_REF_SLUG=$GITHUB_REF_SLUG"
echo "GITHUB_REF_NAME=$GITHUB_REF_NAME"
echo "GITHUB_REF_NAME_SLUG=$GITHUB_REF_NAME_SLUG"
echo "GITHUB_SHA_SHORT=$GITHUB_SHA_SHORT"
所有操作系统(Linux, macOS和Windows)的演示也可以在存储库的演示工作流文件!
要将其设置为环境变量,我使用以下语法:
- name: Extract branch name
shell: bash
run: echo "::set-env name=BRANCH_NAME::$(echo ${GITHUB_REF#refs/heads/} | sed 's/\//_/g')"
- name: Test
run: echo "${BRANCH_NAME}"
我发现这个语法在这里:Github动作-启动worflows#如何定义环境变量?# 68
Rmq: sed 's/\//_/g'将用_替换分支名称中的/
