Six lessons deep, one goal: a repo that tests and ships itself.
What you covered
💡 The Bottom Line, one more time
GitHub Actions puts your CI/CD where your code already lives: YAML workflow files in .github/workflows, versioned and reviewed like everything else in the repo. A workflow is jobs made of steps, running on fresh runners; uses pulls in a published action, run executes your own commands. Triggers decide when it all fires — push, pull_request, a cron schedule, or a manual workflow_dispatch button — with branch and path filters keeping runs relevant. Secrets keep credentials out of your YAML and masked in your logs, with environments adding scoping and approval gates. A real CI pipeline is just those pieces composed: checkout, setup with caching, lint, test across a matrix, build, upload the artifact. And the classic gotchas — workflows that never trigger, secrets that vanish in fork PRs, YAML indentation traps — are all cheap to avoid once you've seen them coming.
What's next
You have working CI. The natural next steps are:
- Continuous deployment — extending the pipeline past CI: deploy jobs, environment protection rules, and OIDC authentication to cloud providers instead of long-lived keys.
- Docker — building and publishing container images from your workflows — there's a full track for it on this site.
- Reusable workflows & composite actions — factoring duplicated YAML across repos into versioned, shared building blocks.
These will show up as new tracks on learn.appcafe.in as they're published — no need to go looking elsewhere.
