Azure Devops Pipeline YAML中的Git标记名称 [英] Git tag name in Azure Devops Pipeline YAML

问题描述

摘要

如何在Azure Devops Pipeline YAML文件中获取当前git标记的名称?

How do I get the name of the current git tag in an Azure Devops Pipeline YAML-file?

我要做什么?

我正在Azure Azure中建立构建管道.当创建新的git标签时，管道触发.然后，我想构建docker映像并用git标记的名称标记它们.

I am setting up a build pipeline in Azure Devops. The pipeline triggers when a new git tag is created. I then want to build docker images and tag them with the git tag's name.

我的YAML管道如下所示:

My YAML pipeline looks something like this:

# Trigger on new tags.
trigger:
  tags:
    include:
    - '*'

stages:
- stage: Build
  jobs:
  - job: Build
    pool:
      vmImage: 'ubuntu-latest'

    steps:
    - script: export VERSION_TAG={{ SOMEHOW GET THE VERSION TAG HERE?? }}
      displayName: Set the git tag name as environment variable

    - script: docker-compose -f k8s/docker-compose.yml build
      displayName: 'Build docker containers'

    - script: docker-compose -f k8s/docker-compose.yml push
      displayName: 'Push docker containers'

我所引用的docker-compose文件是这样的:

And the docker-compose file I am referencing something like this:

version: '3'
services:
  service1:
    image: my.privaterepo.example/app/service1:${VERSION_TAG}
    build:
      [ ... REDACTED ]
  service2:
    image: my.privaterepo.example/app/service2:${VERSION_TAG}
    build:
      [ ... REDACTED ]

如您所见，docker-compose文件中的标签名称取自环境变量VERSION_TAG.在YAML管道中，我试图根据当前的GIT标签设置环境变量VERSION_TAG.那...我怎么得到标签的名字?

As you can see, the tag name in the docker-compose file is taken from the environment variable VERSION_TAG. In the YAML pipeline, I am trying to set the environment variable VERSION_TAG based on the current GIT tag. So... how do I get the name of the tag?

推荐答案

好的，这比我预期的要复杂一些.这是设置变量所需的步骤:

Ok, this was a bit trickier than I expected. Here's the step required to set the variable:

steps:
    - script: VERSION_TAG=`git describe --tags` && echo "##vso[task.setvariable variable=VERSION_TAG]$VERSION_TAG"
      displayName: Set the tag name as an environment variable

此脚本将变量VERSION_TAG设置为最新git标签的名称.它分三个步骤完成:

This script sets the variable VERSION_TAG to the name of the latest git tag. It does so in three steps:

1:git describe --tags

打印当前/最新标签的名称

Prints the name of the current/latest tag

2:VERSION_TAG=`...`

将步骤1的输出设置为局部变量

Sets the output of step 1 to a local variable

3:echo "##vso[task.setvariable variable=VERSION_TAG]$VERSION_TAG"

打印出一个在Azure Devops中设置变量的命令.将在步骤2中设置的局部变量用作值.

Prints out a command that sets the variable in Azure Devops. The local variable set in step 2 is used as the value.
