在我的 azure devops 项目中,我使用模板创建了一个管道。这是我的构建管道的主要 yaml 文件
name: Test-$(Date:yyyyMMdd)$(Rev:.r)
resources:
repositories:
- repository: api
type: git
name: porject/api
ref: master
- repository: front
type: git
name: project/front
ref: master
- repository: strapi
type: git
name: project/strapi
ref: master
trigger:
branches:
include:
- master
pool:
vmImage: 'ubuntu-latest'
workspace:
clean: all
variables:
- name: workingDir
value: project
- name: tfVersion
value: 0.12.29
- name: backendServiceGCP
value: test
- name: backendGCPBucketName
value: test
- name: tfpath
value: test
- name: env
value: dev
stages:
- stage: Terraform
jobs:
- job: Build
displayName: Build Terraform Infra
steps:
# Set and Export env var for api version to deploy
- template: templates/fetch-tag.yml
parameters:
repo: 'api'
envVar: TERRAFORM_API_TAG
# Set and Export env var for front version to deploy
- template: templates/fetch-tag.yml
parameters:
repo: 'front'
envVar: TERRAFORM_FRONT_TAG
# Set and Export env var for strapi version to deploy
- template: templates/fetch-tag.yml
parameters:
repo: 'strapi'
envVar: TERRAFORM_STRAPI_TAG
# Init Terraform providers
- template: templates/tf-init.yml
parameters:
backendServiceGCP: '$(backendServiceGCP)'
backendGCPBucketName: '$(backendGCPBucketName)'
workingDir: '$(workingDir)'
variableFilePath: $(buildSubscription)-common.tfvars
# Plan Terraform Infra to Deploy
- template: templates/tf-plan.yml
parameters:
backendServiceGCP: '$(backendServiceGCP)'
workingDir: '$(workingDir)'
variableFilePath: $(buildSubscription)-common.tfvars
# Publish Public Artifact with Terraform ressources to deploy
- template: templates/publish-artifact.yml
parameters:
tfpath: '$(tfpath)'
当我尝试运行管道时,出现以下错误:
Encountered error(s) while parsing pipeline YAML:
Job Build: The step name version appears more than once. Step names must be unique within a job.
Job Build: The step name version appears more than once. Step names must be unique within a job.
Job Build: The step name version appears more than once. Step names must be unique within a job.
Job Build: The step name version appears more than once. Step names must be unique within a job.
Job Build: The step name version appears more than once. Step names must be unique within a job.
我实在不明白为什么。
这是我在名为 publish-artifact.yml
的管道中使用的模板示例:
parameters:
tfPath: ''
steps:
- task: CopyFiles@2
inputs:
sourceFolder: ${{ parameters.tfpath }}
contents: |
tfplan
**/*.tf
**/*.tfvars
**/*.json
!**/.terraform
**/*.sh
targetFolder: $(Build.ArtifactStagingDirectory)
- task: PublishBuildArtifacts@1
inputs:
pathtoPublish: $(Build.ArtifactStagingDirectory)
artifactName: tf
我的工作名称做错了什么?
最佳答案
Azure Devops 支持将一个步骤的输出变量作为下一步的输入传递。请参阅this ticket :
我们可以这样命名一个步骤:
steps:
- script: echo test
name: ScriptName
- task: PowerShell@2
inputs:
targetType: 'inline'
script: |
Write-Host '##vso[task.setvariable variable=xxx;isOutput=true;]xxx'
name: PSName
名称
必须是唯一的,以便我们可以使用格式$(referencename.variablename)
来访问特定步骤的输出变量。
该错误表明模板中的某些步骤具有相同的名称版本
!并且这是不支持的。 关于出现此问题的原因:
1.您多次调用同一个模板,这是导致您问题的主要原因。
当 processing the pipeline 时,DevOps 首先展开模板,因此,如果您的 fetch-tag
模板有一个名为 version
的步骤,则最终扩展的 azure-pipeline.yml 将为:
stages:
- stage: Terraform
jobs:
- job: Build
displayName: Build Terraform Infra
steps:
- task: PowerShell@2
inputs:
targetType: 'inline'
script: |
Write-Host "Hello World"
name: version
...
- task: PowerShell@2
inputs:
targetType: 'inline'
script: |
Write-Host "Hello World"
name: version
...
- task: PowerShell@2
inputs:
targetType: 'inline'
script: |
Write-Host "Hello World"
name: version
...
2.您可能还需要检查不同模板中是否存在同名步骤。
我们可以在一个管道中多次调用相同的模板,但我们不能调用其中有命名步骤的相同模板。因为管道将多次扩展模板,并且最终管道将包含许多具有相同名称的步骤。并且不支持这一点,因为名称应该是唯一的。
解决方案:
1.如果您不需要使用上述输出变量,请删除步骤中的 name
元素。
2.或者您可以制作多个 fetch-tag.yml
副本,并将它们命名为 fetch-tag-api.yml、fetch-tag-front.yml 和 fetch-tag-strapi.yml 。将这三个文件中的referenceName version
重命名为version1、version2什么的。然后您可以使用以下命令运行管道:
steps:
# Set and Export env var for api version to deploy
- template: templates/fetch-tag-api.yml
parameters:
repo: 'api'
envVar: TERRAFORM_API_TAG
# Set and Export env var for front version to deploy
- template: templates/fetch-tag-front.yml
parameters:
repo: 'front'
envVar: TERRAFORM_FRONT_TAG
# Set and Export env var for strapi version to deploy
- template: templates/fetch-tag-strapi.yml
parameters:
repo: 'strapi'
envVar: TERRAFORM_STRAPI_TAG
