KodeKloud Notes

In this lesson, we’ll recap the complete end-to-end CI/CD setup using Google Cloud Build, GitHub, and Artifact Registry. Once configured, any push to the main branch will automatically build and publish your Docker image.

Pipeline Overview

Step	Action	Outcome
1	Define Build Steps	Update `cloudbuild.yaml` with build & push instructions.
2	Commit to GitHub	Push your pipeline code to the GitHub repository.
3	Open a Pull Request	Request review by targeting the `main` branch.
4	Merge into Main	Approved PR merge triggers the pipeline.
5	Execute Cloud Build	Cloud Build runs automatically on the new commit.
6	Build & Push Docker Image	Image is built and published to Artifact Registry.

Prerequisite

Ensure your GitHub repo is connected to Cloud Build and you have permissions on the Artifact Registry.

1. Update `cloudbuild.yaml`

Place this file in the root of your repository to define your build pipeline. Example configuration:

steps:
  - name: 'gcr.io/cloud-builders/docker'
    args:
      - 'build'
      - '-t'
      - 'us-central1-docker.pkg.dev/PROJECT_ID/REPO/IMAGE:$SHORT_SHA'
      - '.'
  - name: 'gcr.io/cloud-builders/docker'
    args:
      - 'push'
      - 'us-central1-docker.pkg.dev/PROJECT_ID/REPO/IMAGE:$SHORT_SHA'
images:
  - 'us-central1-docker.pkg.dev/PROJECT_ID/REPO/IMAGE:$SHORT_SHA'

2. Commit to GitHub

Save your changes and push to a feature branch:

git add cloudbuild.yaml
git commit -m "chore: configure Cloud Build pipeline"
git push origin feature/ci-cd-setup

3. Open a Pull Request

In GitHub, open a PR from feature/ci-cd-setup into main. Assign reviewers to validate:

Review cloudbuild.yaml
Check naming and region settings
Verify IAM permissions for Cloud Build

4. Merge into Main

Once approved, merge the PR. Cloud Build only triggers on commits to the main branch.

Warning

Avoid merging untested changes directly into main. Always validate in a staging or development branch first.

5. Trigger Cloud Build

After merging, Cloud Build detects the new commit on main and executes your defined steps. Monitor builds via:

gcloud builds list --filter="status=WORKING"

Or in the Cloud Console under Cloud Build → History.

6. Build and Publish Docker Image

Cloud Build will:

Build the Docker image.
Push it to Artifact Registry in the specified region (e.g., us-central1).

With artifacts versioned and stored securely, your pipeline is now fully automated.
