GitHub Actions — Learning Roadmap¶

Follow the course in order for the smoothest path. Allow 6–8 weeks at 5–8 hours per week, or compress Modules 1–6 if you already run CI elsewhere.

Path overview¶

Course overview — scope, prerequisites, outcomes (index)
Modules 1–16 — beginner foundations through expert production ops
Labs / quizzes / projects — hands-on under ~/rebash-github-actions/module-NN
Capstone — production CI/CD platform (capstone)
Interview & certifications — GitHub Foundations / Actions / Administration

Pacing guide¶

Week	Modules	Focus	Approx. time
1	1–2	CI/CD concepts; first workflow	6–8 h
2	3–4	Runners; matrix & conditionals	6–8 h
3	5–6	Secrets, OIDC intro; artefacts & cache	6–8 h
4	7–8	Docker/GHCR; Kubernetes deploy	8–10 h
5	9–10	Terraform plan/apply; multi-cloud OIDC stubs	8–10 h
6	11–12	Security scanning; testing layers	8–10 h
7	13–14	Releases; composite & reusable workflows	6–8 h
8	15–16	Production environments; troubleshooting	8–10 h

Adjust pace if you skip cloud deploy labs until sandbox accounts are ready — Modules 9–11 remain valuable offline.

Diagrams¶

All course diagrams are Excalidraw sources under docs/assets/excalidraw/. Key assets for Modules 9–16:

gha-terraform-pipeline.svg — init/validate/plan/apply gates
gha-multi-cloud.svg — OIDC to AWS, Azure, GCP
gha-security.svg — CodeQL, Trivy, SBOM, pinning
gha-testing.svg — unit/integration/E2E job graph
gha-release-pipeline.svg — SemVer tags and GitHub Releases
gha-reusable-components.svg — composite actions and reusable workflows
gha-production.svg — staging → production promotion
gha-troubleshooting.svg — failed-job ladder

After Module 16¶

Complete the Capstone — enterprise platform with reusables, OIDC, scanning, releases
Review Interview questions for workflow design and production scenarios
Cross-study Jenkins or Git for pipeline comparisons in interviews
