Learning project for Lab 3: CI/CD pipeline architecture.

Pipeline stages

This repository uses a multi-stage GitHub Actions workflow:

test -> build -> deploy_staging -> verify_staging -> deploy_production

• test: runs unit tests from tests/test_core.py
• build: creates build artifact artifact/build.txt
• deploy_staging: simulates staging deployment using the artifact
• verify_staging: runs post-deploy smoke verification
• deploy_production: simulates production deployment after manual approval

Manual approval for production

The deploy_production job uses GitHub Environment production. To enable manual approval:

1. Open repository settings.
2. Go to Environments.
3. Create environment production.
4. Add Required reviewers.

After that, production deployment will wait for approval.

How to demonstrate failures required by the lab

1. Break unit test in tests/test_core.py and push commit.
2. Confirm pipeline fails on stage test.
3. Fix the test and push again.
4. Run workflow manually with input force_verify_fail=true.
5. Confirm pipeline fails on verify_staging and production is not executed.
6. Run again with force_verify_fail=false.
