한눈에 보기

GitHub Actions is GitHub's native CI/CD system for automating tests, builds, deployments, and code quality checks. Workflows trigger on events (push, pull request, schedule). Popular with startups (free tier, tight GitHub integration) and enterprises (security, no external vendor). Mid-career salary: $110-155k. Senior architects design workflows for complex deployments (multiple services, blue-green, canary). Mastery: 3-5 weeks.

GitHub Actions Mastery이란

GitHub Actions is GitHub's native CI/CD (continuous integration/continuous deployment) automation platform. Workflows are YAML-defined pipelines that run tests, linting, builds, and deployments automatically when code is pushed or PR is created. Workflows trigger on events: push, pull request, schedule (cron), webhook. Key components: (1) workflows (YAML files in .github/workflows/), (2) jobs (parallel or sequential units of work), (3) steps (individual commands or actions), (4) secrets (encrypted credentials), (5) artifacts (build outputs). Actions leverage reusable components (actions) from GitHub Marketplace.

❓ 자주 묻는 질문

What's the difference between GitHub Actions and Jenkins?

GitHub Actions is cloud-hosted (no server to manage), tight GitHub integration, free for public repos. Jenkins is self-hosted (more control, more ops work). Actions wins for simplicity; Jenkins wins for complex on-premise requirements.

How do I store secrets (API keys, passwords) safely?

Use GitHub Secrets. Encrypted at rest, never logged. Access in workflows via `${{ secrets.MY_SECRET }}`. Secrets are masked in logs (show as ****).

Can I run Actions on pull requests and branches?

Yes. Use `on: [pull_request, push]`. Different workflows can run on different triggers. Example: lint on PR, deploy on main branch push.

How do I parallelize jobs?

Use `jobs` with multiple entries. Each job runs in parallel by default. Use `needs: [job1, job2]` to create dependencies (job3 waits for job1/2).

Can I use self-hosted runners?

Yes. Self-hosted runners run workflows on your own servers. Useful for private networks, GPU access, or larger workloads. More ops responsibility.
