CI/CD

1. Overview

CI (Continuous Integration):
- Automated process where code changes are frequently integrated into a shared repository.
- Each integration is verified by automated builds and tests.
- Aims to detect errors quickly, enhance software quality, and reduce the time it takes to release software.
CD (Continuous Delivery/Continuous Deployment):
- Continuous Delivery refers to the practice of keeping code in a deployable state.
  - Code changes automatically prepared for a release to production.
  - Manual approval required for production deployment.
- Continuous Deployment allows for automatic deployment of every change that passes automated tests to production.
- Aims to enable frequent updates and quick delivery of new features to end-users.
Key Components:
- Version Control Systems (e.g., Git)
- Automated Testing (unit, integration, functional tests)
- Build Automation Tools (e.g., Jenkins, CircleCI, Travis CI)
- Deployment Automation (e.g., Kubernetes, Docker)
