Name: pantheon-ai/azure-pipelines-toolkit
Rating: 0.97 (1 reviews)
Author: pantheon-ai

Comprehensive reference for Azure Pipelines YAML syntax and structure.

Pipeline Structure

Azure Pipelines supports three main structures:

1. Multi-Stage Pipeline

stages:
- stage: Build
  jobs:
  - job: BuildJob
    steps:
    - script: echo "Building"

2. Multi-Job Pipeline

jobs:
- job: Job1
  steps:
  - script: echo "Job 1"
- job: Job2
  steps:
  - script: echo "Job 2"

3. Single-Job Pipeline

steps:
- script: echo "Single job"

Best Practices

Always pin task versions: Use TaskName@2 not TaskName@*
Use specific VM images: Use ubuntu-22.04 not ubuntu-latest
Use displayName: Add descriptive names for stages, jobs, and steps
Use caching: Cache dependencies to speed up builds
Use templates: Reuse common configurations
Use variable groups: Organize variables for different environments
Set timeouts: Prevent hung jobs with timeoutInMinutes
Use conditions: Control when stages/jobs run
Clean checkout: Use clean: true for consistent builds
Use deployment jobs: For deployments to environments
