CI/CD Basics in GCP

Imagine you’re working on an app

Every time you make a small change:

• You manually test
• Upload code
• Deploy again

This becomes slow, repetitive, and error-prone

Now imagine this instead…

You push code to GitHub
It automatically builds
Tests run instantly
App gets deployed

That’s CI/CD

What is CI/CD?

CI/CD stands for:

• CI (Continuous Integration) → Automatically build & test code
• CD (Continuous Deployment/Delivery) → Automatically deploy code

It automates the entire development pipeline

CI/CD Pipeline Stages

1. Code Commit → Push code to repository
2. Build → Compile and package app
3. Test → Run automated tests
4. Deploy → Release to production

CI/CD Tools in GCP

Technical Example (Cloud Build)

Create a cloudbuild.yaml file:

Run build:

This builds and pushes your container automatically

CI/CD Workflow in GCP

1. Developer pushes code
2. Cloud Build triggers automatically
3. App is tested
4. Image is stored
5. Deployed to Cloud Run/App Engine

1. Startup Development

• Faster feature releases
• Less manual work

2. E-commerce Platforms

• Frequent updates without downtime

3. Large Teams

• Multiple developers working together
• Automated integration

4. Mobile App Backend

• Continuous deployment of APIs
