Utilizar variáveis secretas e nãosecretas de um grupo de variáveis num Pipeline do Azure

  • Artigo

Serviços do Azure DevOps | Azure DevOps Server 2022 | Azure DevOps Server 2020

Neste exemplo, utilize a CLI do Microsoft Azure DevOps (extensão azure-devops) para criar um Pipeline do Azure que aceda a um grupo de variáveis que contenha variáveis secretas e nãosecretas.

Este script demonstra três operações:

  • Definir um Pipeline do Azure com ficheiros YAML
  • Criar um grupo de variáveis com variáveis nãosecretas e secretas para utilização num pipeline
  • Executar o pipeline com a CLI do Azure DevOps, que também abre uma página Web para monitorizar o processamento e a saída da execução do pipeline

Pré-requisitos

Script de exemplo

Primeiro, guarde o seguinte ficheiro YAML, que define o Pipeline do Azure, para azure-pipelines.yml no diretório raiz do repositório local. Em seguida, adicione e consolide o ficheiro no GitHub e envie o ficheiro para o repositório remoto do GitHub.

parameters:
- name: image
  displayName: 'Pool image'
  default: ubuntu-latest
  values:
  - windows-latest
  - windows-latest
  - ubuntu-latest
  - ubuntu-latest
  - macOS-latest
  - macOS-latest
- name: test
  displayName: Run Tests?
  type: boolean
  default: false

variables:
- group: "Contoso Variable Group"
- name: va
  value: $[variables.a]
- name: vb
  value: $[variables.b]
- name: vcontososecret
  value: $[variables.contososecret]

trigger:
- main

pool:
  vmImage: ubuntu-latest

steps:
- script: |
    echo "Hello, world!"
    echo "Pool image: ${{ parameters.image }}"
    echo "Run tests? ${{ parameters.test }}"
  displayName: 'Show runtime parameter values'

- script: |
    echo "a=$(va)"
    echo "b=$(vb)"
    echo "contososecret=$(vcontososecret)"
    echo
    echo "Count up to the value of the variable group's nonsecret variable *a*:"
    for number in {1..$(va)}
    do
        echo "$number"
    done
    echo "Count up to the value of the variable group's nonsecret variable *b*:"
    for number in {1..$(vb)}
    do
        echo "$number"
    done
    echo "Count up to the value of the variable group's secret variable *contososecret*:"
    for number in {1..$(vcontososecret)}
    do
        echo "$number"
    done
  displayName: 'Test variable group variables (secret and nonsecret)'
  env:
    SYSTEM_ACCESSTOKEN: $(System.AccessToken)

Depois de publicar o ficheiro YAML no GitHub, substitua os marcadores de posição no seguinte script bash e, em seguida, execute o script.

Limpar os recursos

Após a execução do exemplo de script, podem ser utilizados os seguintes comandos para remover o grupo de recursos e todos os recursos associados ao mesmo.

az pipelines variable-group delete --group-id $variableGroupId --yes
az pipelines delete --id $pipelineId --yes
az devops service-endpoint delete --id $githubServiceEndpointId --yes
az devops project delete --id $projectId --yes
export AZURE_DEVOPS_EXT_GITHUB_PAT=""
az storage account delete --name $storageAccountName --resource-group $resourceGroupName --yes
az group delete --name $resourceGroupName --yes
az devops configure --defaults organization="" project=""
