Azure DevOps CI/CD

Introduction

Azure DevOps is a cloud-based service that provides a set of development tools for software development and project management. CI/CD stands for Continuous Integration and Continuous Deployment, which are practices that enable software teams to deliver code changes more frequently and reliably.

Key Concepts

**Continuous Integration (CI)**: The practice of automatically testing and merging code changes into a shared repository.
**Continuous Deployment (CD)**: The practice of automatically deploying code changes to a production environment following successful CI.
**Pipeline**: A set of automated processes that allow you to build, test, and deploy your application.
**Agent**: A software component that runs a job in a pipeline or deployment.

Step-by-Step Process

Creating a Pipeline in Azure DevOps


                graph TD;
                    A[Start] --> B[Create a New Project];
                    B --> C[Define Pipeline];
                    C --> D[Add Build Tasks];
                    D --> E[Configure Triggers];
                    E --> F[Run Pipeline];
                    F --> G[Review Results];
                    G --> H[Deploy to Production];
                    H --> I[End];

Note: Ensure you have the necessary permissions to create and run pipelines in Azure DevOps.

Example YAML Pipeline Configuration


            # azure-pipelines.yml
            trigger:
              - master

            pool:
              vmImage: 'ubuntu-latest'

            steps:
              - script: echo Building...
                displayName: 'Build Step'
              - script: echo Deploying...
                displayName: 'Deploy Step'

Best Practices

Keep your pipeline simple and organized.
Use environment variables for sensitive data.
Regularly review and update your CI/CD processes.
Implement testing at every stage of the pipeline.
