Overview
What this challenge is about.
Set up Flux v2, automate production promotion PRs, and enforce deployment freezes. Complete the challenge and earn a verifiable certificate.
The scenario
Coilworks builds vertical software for HVAC contractors and runs a small platform team supporting roughly a dozen engineers across dev, staging, and production environments. As release frequency has grown, the manual production promotion step has become the team's most common source of misconfigured deploys.
The Brief
What you'll do, and what you'll demonstrate.
Replace manual, hand-edited production image promotions with an automated pull-request flow that bumps image tags after staging passes, enforces platform-team approval, and blocks deploys during freeze windows.
Earning criteria — what you'll demonstrate
- Configure Flux image automation with semver policies to bump container image tags automatically
- Design a promotion pull-request flow triggered by a green staging signal
- Enforce approval policy with CODEOWNERS and GitHub branch protection
- Implement deployment freeze windows as code rather than as documentation
- Document a promotion pipeline so a new engineer can operate it unaided

Careers
Career paths this challenge builds toward
Completing this challenge demonstrates skills that transfer directly to these roles:
Platform Engineer
This challenge mirrors core platform work: building self-service, auditable release paths so product teams ship safely without manual gatekeeping. You leave able to stand up GitOps promotion pipelines that scale across services and environments.

Release Engineer
Designing approval gates and freeze windows is the heart of release engineering. This challenge builds your ability to encode promotion and approval rules as enforceable tooling rather than convention, the differentiator for release-focused roles.
