Definitions

Term	Definition
Artifact	item from a git repository or a build pipeline
Stages	steps to deploy and validate a software a stage contains jobs
Job	subparts of a stage, contains tasks to execute listed as steps a job runs on a agent or can be manually ran
Tasks / Steps	subparts of a job, those are the concreate action to execute
Release pipeline definition	steps to execute to get the artefacts, install and validate the software template to run a release
Release agent	the one who execute the tasks defined in the release pipeline definition it is the same agent as the one used for the build

Release variables

• Predefined variables

YAML

• YAML schema reference
• Specify jobs in your pipeline
• Template types & usage
• Approvals in environments with multi-stage YAML pipelines

Exemple

# do not trigger the pipeline on events trigger: none parameters: - name: myStepList type: stepList default: - bash: echo "We are on $(MyVar)" # If you have a single stage, you can omit the stages keyword and directly specify the jobs keyword stages: - stage: CI displayName: CI stage # remove implicite depency on the previous stage, the stages will run in parallel dependsOn: [] jobs: - job: ci_job pool: MyPool variables: MyVar: 'CI' # If you have a single stage and a single job, you can omit the stages and jobs keywords and directly specify the steps keyword steps: - bash: echo "We are on CI" - pwsh: | Write-Host "We are on CI" - task: PowerShell@2 displayName: 'PowerShell Script' inputs: targetType: filePath filePath: './$(System.DefaultWorkingDirectory)/Folder/Script.ps1' arguments: '-Arg1 "$(MyVar)"' # disable the task enabled: false - stage: DEMO displayName: DEMO stage dependsOn: [] jobs: # use deployment job with environment and strategy to use the approval mechanism - deployment: demo_job environment: DEMO variables: MyVar: 'DEMO' strategy: runOnce: deploy: steps: ${{ parameters.myStepList }}

PowerShell task

- task: PowerShell@2 displayName: 'PowerShell Script' inputs: targetType: filePath filePath: 'MyScript.ps1' arguments: '-Arg1 "Arg1"' - task: PowerShell@2 displayName: 'PowerShell Script' inputs: targetType: inline script: | 'cmd1' 'cmd2' - powershell: 'cmd' # 4 blank characters before the command - powershell: | 'cmd1' 'cmd2' # pwsh runs PowerShell Core, which must be installed on the agent or container. - pwsh: 'cmd'

Variables

# scope: root, stage, job variables: variable_name: 'value'

Runtime parameters

Ces paramètres sont sélectionnable à chaque lancement de la pipeline.

parameters: - name: my_parameter displayName: My parameter type: string default: Value1 values: - Value1 - Value2

Repositories

• Supported source repositories
• Resources in YAML
• Multi-repo checkout

resources: repositories: - repository: RepoId # A-Z, a-z, 0-9, and underscore name: RepoName # repository name (format depends on `type`) type: git ref: master steps: - checkout: self # checkout in C:\agent\_work\1\s\CurrentRepoId - checkout: RepoId # checkout in C:\agent\_work\1\s\RepoId

Condition

stages: - stage: Stage1 condition: eq(variables.Var1, 'Value1') jobs: - job: steps: - powershell: 'cmd' condition: eq('${{ parameters.Param1 }}', 'Value1')

Steps of a release

1. Build the software with a pipeline
   • validate product quality (unit tests, SonarCloud)
2. Deploy the software
   • validate runtime stability (compare telemetry with previous version)
3. Release the feature
   • validate feature usage
