⏱ Duration: 5 Hours
📚 Learning Objectives
- Understand Continuous Integration (CI)
- Understand Continuous Delivery/Deployment (CD)
- Learn pipeline components
- Design a basic pipeline
📖 Core Concepts
Continuous Integration (CI)
Developers frequently merge code changes into a shared repository. Each merge triggers automated builds and tests.
CI Benefits:
- Early bug detection
- Reduced integration problems
- Faster feedback
- Higher code quality
CI Process:
1. Developer pushes code
2. CI server detects change
3. Build application
4. Run automated tests
5. Report resultsContinuous Delivery vs Deployment
Continuous Delivery:
Code → Build → Test → [Manual Approval] → Deploy
(Human decides when to release)
Continuous Deployment:
Code → Build → Test → Deploy
(Automatic release after tests pass)Pipeline Stages
Typical Pipeline:
┌─────────┬─────────┬─────────┬─────────┬─────────┐
│ Build │ Test │ Scan │ Package │ Deploy │
├─────────┼─────────┼─────────┼─────────┼─────────┤
│ Compile │ Unit │Security │ Docker │ Staging │
│ Install │ Integr. │ Lint │ Push │ Prod │

Design Your First Pipeline
Map out pipeline stages for a Python web application:
- What happens in each stage?
- What tools would you use?
- What triggers the pipeline?
