Azure Pipelines Cheat Sheet

• A cloud-based platform for automating code build, test, and deployment workflows using CI/CD pipelines.
• Automates software delivery across development, test, and production environments.
• Works with multiple languages and platforms (e.g., .NET, Java, Node.js, Python).
• Integrates with GitHub, Azure Repos, Bitbucket, and other Git providers.
• Supports both YAML (as code) and visual designer for pipeline configuration.

Azure Pipelines Key Features

• Cross-platform support
  Build and deploy applications on Windows, Linux, and macOS. Choose between Microsoft-hosted or self-hosted agents depending on your environment needs.
• Language-agnostic execution
  Supports a wide range of languages such as .NET, Java, Python, Node.js, and more. You can build, test, and deploy virtually any type of application.
• YAML pipeline as code
  Define pipelines using YAML files stored in your code repository. This enables version control, easier collaboration, and consistent workflows.
• Visual pipeline editor
  Create and modify pipelines using a drag-and-drop web interface. Ideal for teams that prefer a low-code or UI-driven setup.
• Secure secrets management
  Store sensitive values as encrypted variables or integrate with Azure Key Vault. Secrets are masked during runtime and hidden in logs.
• Custom tasks and templates
  Add functionality with marketplace tasks or define your own using scripts. Reuse pipeline logic across projects using YAML templates.
• Parallel and matrix jobs
  Run multiple jobs at the same time or across different configurations. This reduces build times and improves testing coverage.
• Built-in caching
  Cache dependencies and files to speed up subsequent pipeline runs. Helps optimize performance and reduce external download times.

Azure Pipelines Important Terminologies

• Pipeline: Defines the full CI/CD process from source code to deployment.
• Stage: Logical grouping of jobs (e.g., build, test, release).
• Job: Set of steps executed together on an agent.
• Step: Single task or command (e.g., script, install, test).
• Agent: Virtual machine that runs jobs (Microsoft-hosted or self-hosted).
• Artifact: Output files (e.g., build results) used in later stages.
• Trigger: Event (e.g., push to branch) that starts the pipeline.

Azure Pipelines Use Cases

• Continuous integration and delivery for web, desktop, and mobile apps.
• Automated testing of code changes with reporting.
• Deployment of infrastructure using IAC tools.
• Create and distribute packages (NuGet, npm, Python).
• Multi-environment deployments with approvals and gates.
• Running pipelines conditionally based on code changes.
• Coordinating microservice build and deploy workflows.

Azure Pipelines Integration Options

• Azure Repos: First-party Git integration.
• GitHub: CI/CD integration with pull request triggers.
• Bitbucket: Connect for builds and deployments.
• Azure Artifacts: Share and consume build outputs.
• Azure Container Registry: Push Docker images from pipelines.
• Azure Kubernetes Service (AKS): Deploy apps to Kubernetes clusters.
• Azure Key Vault: Inject secrets securely into pipeline tasks.
• Terraform/ARM/Bicep: Infrastructure as code support.
• Notification apps (Slack, Teams, Email): Send pipeline status updates through service hooks or messaging tasks.
