Azure Devops:模板使用序列类型参数来生成作业和阶段

Question

模板变量似乎不支持序列类型，但模板参数支持它(在Microsoft文档中称为对象类型(，以及JobList类型和StageList类型，但它们似乎只是具有定义模式的序列。

当迭代对象类型参数以生成步骤时，我没有遇到任何问题，但当我尝试这样做以生成作业和阶段时，我遇到了一个错误，称为"不需要序列"。

所以结果必须是这样的：

# main.yml:
trigger: none
extends:
template: template.yml
parameters:
PROJECTNAME: foo.bar
DEPLOYMENTTARGETS:
- stage:
jobs:
- deployment:
environment:
name: TEST
tags: Web # tag must be comma separated string which is also kinda weird
- stage:
jobs:
- deployment:
environment:
name: PROD
tags: Web

# template.yml:
parameters:
- name: PROJECTNAME
type: string
default: ""
- name: DEPLOYMENTTARGETS
type: stageList # I was expecting object to be working
default: []
variables:
- group: LoginSecrets
stages:
- ${{ each  deploymentTarget in parameters.DEPLOYMENTTARGETS }}: # iterating through an object here will result in error: 'A sequence was not expected', iterating through  a StageList is OK
- stage: Deploy_${{replace(parameters.PROJECTNAME,'.','_')}}_${{replace(deploymentTarget.jobs[0].environment.name,'-','')}}_${{replace(replace(deploymentTarget.jobs[0].environment.tags,',','_'),'-','')}}_Stage # assuming each stage contains only one deployment job. We also iterate through jobs here if required.
dependsOn: BuildAndPublish_${{replace(parameters.PROJECTNAME,'.','_')}}_Stage
jobs:
- deployment: Deploy_${{replace(parameters.PROJECTNAME,'.','_')}}_Job
environment:
name: ${{deploymentTarget.jobs[0].environment.name}}
resourceType: VirtualMachine
tags: ${{deploymentTarget.jobs[0].environment.tags}}
strategy:
runOnce:
deploy:
steps:
- pwsh: $(Pipeline.Workspace)/${{parameters.PROJECTNAME}}/pipelineRelease.ps1
env:
LOGINNAME: $(loginName)
LOGINPASSWORD: $(loginPassword)
PROJECTNAME: ${{parameters.PROJECTNAME}}

但我本以为这样的东西会起作用：

# main.yml:
trigger: none
extends:
template: template.yml
parameters:
PROJECTNAME: foo.bar
DEPLOYMENTTARGETS:
- EnvName: TEST
Tags: Web
- EnvName: PROD
Tags: Web
# template.yml:
parameters:
- name: PROJECTNAME
type: string
default: ""
- name: DEPLOYMENTTARGETS
type: object # instead of StageList, I passed an object here
default: []
variables:
- group: LoginSecrets
stages:
- ${{ each  deploymentTarget in parameters.DEPLOYMENTTARGETS }}: # error here
- stage: Deploy_${{replace(parameters.PROJECTNAME,'.','_')}}_${{replace(deploymentTarget.EnvName,'-','')}}_${{replace(replace(deploymentTargetTags,',','_'),'-','')}}_Stage
dependsOn: BuildAndPublish_${{replace(parameters.PROJECTNAME,'.','_')}}_Stage
jobs:
- deployment: Deploy_${{replace(parameters.PROJECTNAME,'.','_')}}_Job
environment:
name: ${{deploymentTarget.EnvName}}
resourceType: VirtualMachine
tags: ${{deploymentTarget.Tags}}
strategy:
runOnce:
deploy:
steps:
- pwsh: $(Pipeline.Workspace)/${{parameters.PROJECTNAME}}/pipelineRelease.ps1
env:
LOGINNAME: $(loginName)
LOGINPASSWORD: $(loginPassword)
PROJECTNAME: ${{parameters.PROJECTNAME}}

Azure Devops:Template使用序列类型参数生成作业并暂存

恐怕我们必须使用stageList而不是object来传输二维数组。

这是因为参数在main.yml中被定义为二维数组，但如果我们在template.yml文件中将此数组定义为object。在这种情况下，我们无法循环模板文件中的对象。

您可以查看文档"循环通过"参数以了解更多详细信息。

此外，您可以查看类似的线程以了解一些详细信息。
