What is CI/CD?

Continuous Integration (CI) and Continuous Delivery (CD) are DevOps practices that automate the delivery of code changes to production. 🔄

  • CI involves merging code changes into a shared repository frequently (e.g., multiple times a day) and running automated tests to catch issues early.
  • CD extends CI by automating the deployment process, ensuring code can be reliably released to production at any time.

Key Concepts

  1. Version Control (e.g., Git)

  2. Automated Testing

  4. Deployment Pipeline

Tools and Platforms

Tool Purpose
GitHub Actions CI/CD workflow automation
GitLab CI/CD Built-in CI/CD pipelines
CircleCI Cloud-based CI/CD platform
Travis CI Open-source CI service

Practice Steps

  1. Set up a version control system.
  2. Automate testing with frameworks like Jest or Selenium.
  3. Configure a build tool to compile and package code.
  4. Integrate with a deployment tool for automated releases.
  5. Monitor and optimize the pipeline continuously.

Common Challenges

  • Environment consistency: Use Docker for containerized environments. 🐳
  • Test coverage: Ensure tests cover all critical paths.
  • Feedback loops: Implement real-time notifications for build failures.
