101 — Introduction to CI/CD

Beginner

Understand Continuous Integration and Continuous Deployment fundamentals, workflows, and benefits for modern software development.

Learning Objectives

1
Understand CI/CD concepts and terminology
2
Learn the CI/CD pipeline stages
3
Create your first automated workflow
4
Understand benefits and best practices
Step 1

Verify GitHub CLI installation

Check if you have the GitHub CLI (gh) installed, which we'll use for CI/CD automation.

Commands to Run

gh --version
gh auth status

What This Does

GitHub CLI (gh) streamlines CI/CD setup with GitHub Actions. CI (Continuous Integration) automatically builds and tests code on every commit. CD (Continuous Deployment) automatically deploys tested code to production. CD (Continuous Delivery) automates deployment to staging with manual production approval.

Expected Outcome

gh CLI version displayed (e.g., 'gh version 2.x.x') and authentication status showing you're logged in to GitHub.

Pro Tips

  • 1
    Install gh CLI from https://cli.github.com if not installed
  • 2
    Login with: gh auth login
  • 3
    CI catches bugs early by testing every commit
  • 4
    CD delivers features faster through automation
  • 5
    GitHub Actions provides free CI/CD for public repos

Common Mistakes to Avoid

  • ⚠️Skipping authentication setup (gh auth login)
  • ⚠️Not understanding the difference between CI, CD (Delivery), and CD (Deployment)
