# azure-devops-pipelines

This rule guides Azure DevOps Pipeline YAML structure, testing, security, and deployment. Use it when reviewing or maintaining pipeline files.

## What it does

The rule applies to `azure-pipelines.yml`, `azure-pipelines*.yml`, and `*.pipeline.yml`. It sets conventions such as two-space YAML indentation and meaningful names for pipelines, stages, jobs, and steps. Complex flows should use stages and jobs with explicit dependencies, while templates keep repeated parts reusable.

The guidance covers variables and parameters, dependency caching, artifact handling, test results, code coverage, and quality gates. Security sections point to Azure Key Vault, variable groups, least-privilege service connections, and security scans. Deployment guidance includes environment promotion, health checks, rollback, and infrastructure as code.

Mixing build and deployment logic in one stage is listed as an anti-pattern. The example uses `UseDotNet@2`, `DotNetCoreCLI@2`, `AzureWebApp@1`, `ubuntu-latest`, and the `main` branch; those example values are not universal requirements.

## Requirements
- Works with: Azure DevOps

## Install

### GitHub Copilot (native platform)

**Manually: put the files in place**
- File: `.github/instructions/azure-devops-pipelines.instructions.md` — The applyTo field sets which files it applies to

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/azure-devops-pipelines.md` — The paths frontmatter field limits the files: move applyTo from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### Cursor

**Manually: put the files in place**
- File: `.cursor/rules/azure-devops-pipelines.mdc` — Frontmatter: description, globs, alwaysApply. Move applyTo from the source into globs, or the rule will not attach on its own

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/azure-devops-pipelines.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/azure-devops-pipelines.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/instructions/azure-devops-pipelines.instructions.md

## When to use it
- structure an Azure DevOps Pipeline YAML file
- split build and deployment into stages
- add tests, coverage, and quality gates
- manage secrets with Azure Key Vault and variable groups
- trigger builds by branch and path changes

## Example prompts
- Review `azure-pipelines.yml` against the azure-devops-pipelines rule and flag issues in its stages and jobs.
- Refactor this pipeline by moving repeated steps into templates and adding job dependencies without changing its behavior.
- Check the deployment in `azure-pipelines.yml` for secrets, health checks, rollback, and service connection permissions.

# Azure DevOps Pipeline YAML Best Practices

## General Guidelines

- Use YAML syntax consistently with proper indentation (2 spaces)
- Always include meaningful names and display names for pipelines, stages, jobs, and steps
- Implement proper error handling and conditional execution
- Use variables and parameters to make pipelines reusable and maintainable
- Follow the principle of least privilege for service connections and permissions
- Include comprehensive logging and diagnostics for troubleshooting

## Pipeline Structure

- Organize complex pipelines using stages for better visualization and control
- Use jobs to group related steps and enable parallel execution when possible
- Implement proper dependencies between stages and jobs
- Use templates for reusable pipeline components
- Keep pipeline files focused and modular - split large pipelines into multiple files

## Build Best Practices

- Use specific agent pool versions and VM images for consistency
- Cache dependencies (npm, NuGet, Maven, etc.) to improve build performance
- Implement proper artifact management with meaningful names and retention policies
- Use build variables for version numbers and build metadata
- Include code quality gates (linting, testing, security scans)
- Ensure builds are reproducible and environment-independent

## Testing Integration

- Run unit tests as part of the build process
- Publish test results in standard formats (JUnit, VSTest, etc.)
- Include code coverage reporting and quality gates
- Implement integration and end-to-end tests in appropriate stages
- Use test impact analysis when available to optimize test execution
- Fail fast on test failures to provide quick feedback

## Security Considerations

- Use Azure Key Vault for sensitive configuration and secrets
- Implement proper secret management with variable groups
- Use service connections with minimal required permissions
- Enable security scans (dependency vulnerabilities, static analysis)
- Implement approval gates for production deployments
- Use managed identities when possible instead of service principals

## Deployment Strategies

- Implement proper environment promotion (dev → staging → production)
- Use deployment jobs with proper environment targeting
- Implement blue-green or canary deployment strategies when appropriate
- Include rollback mechanisms and health checks
- Use infrastructure as code (ARM, Bicep, Terraform) for consistent deployments
- Implement proper configuration management per environment

## Variable and Parameter Management

- Use variable groups for shared configuration across pipelines
- Implement runtime parameters for flexible pipeline execution
- Use conditional variables based on branches or environments
- Secure sensitive variables and mark them as secrets
- Document variable purposes and expected values
- Use variable templates for complex variable logic

## Performance Optimization

- Use parallel jobs and matrix strategies when appropriate
- Implement proper caching strategies for dependencies and build outputs
- Use shallow clone for Git operations when full history isn't needed
- Optimize Docker image builds with multi-stage builds and layer caching
- Monitor pipeline performance and optimize bottlenecks
