GitHub Actions Examples

Compact set of focused GitHub Actions samples. Each folder covers one topic: triggers, job flow, artifacts, custom actions, secrets, containers, or security.

Purpose

Show practical patterns without long explanations.

Project List

1. Basic Workflow – first simple workflow and manual trigger
2. Job Dependencies – jobs that wait on others and pass data
3. Issue Events – reacting to issue open / label events
4. Event Triggers – multiple events, path filters, manual dispatch
5. Advanced Execution Patterns – matrix builds, reusable workflow, continue-on-error
6. Custom Actions – local composite / JS / Docker action examples
7. Artifacts and Outputs – share build files and small values between jobs
8. Environment Variables & Secrets – safe use of env vars and secrets
9. Docker Workflows – run jobs in a container + service (e.g. MongoDB)
10. Security – least‑permission tokens, simple script injection guard

Highlights

• Triggers (push, PR, manual, issues)
• Job relationships (needs, matrix)
• Outputs & artifacts
• Custom local actions
• Secrets vs plain env vars
• Container + service usage
• Minimal permission security pattern

Notes

• Short on purpose
• No invented metrics
• Mix and reuse components freely

Order Suggestion

basic-workflow → job-dependencies → issue-events → event-triggers → advanced-execution-patterns → custom-actions → artifacts-and-outputs → env-variables-and-secrets → docker-workflows → security
