CI/CD Pipelines on GCP

Continuous Integration and Continuous Delivery (CI/CD) is the practice of automatically building, testing, and deploying software whenever changes are made. Google Cloud provides a comprehensive set of services for building CI/CD pipelines — Cloud Build for execution, Artifact Registry for artefact storage, Cloud Deploy for managed delivery, and various deployment targets including Cloud Run, GKE, and App Engine.

CI/CD Fundamentals

Continuous Integration (CI)

CI is the practice of frequently merging code changes into a shared repository and automatically building and testing each change:

Step	Purpose	Tool
Code commit	Developer pushes code	Git (CSR, GitHub, GitLab)
Build trigger	Detect the change	Cloud Build triggers
Compile/Build	Compile code, build artefacts	Cloud Build
Unit tests	Run automated tests	Cloud Build
Lint/Static analysis	Check code quality	Cloud Build
Container build	Build Docker images	Cloud Build
Push artefact	Store built artefacts	Artifact Registry
Scan	Vulnerability scanning	Container Analysis
