CI/CD Pipelines (Jenkins, GitLab CI, CircleCI)
Continuous integration & deployment: automate build, test, deploy
CI/CD pipelines automate software delivery by connecting version control to infrastructure: code commit → build → test → deploy to staging/production. Hands-on skill (distinct from best-practices theory): GitHub Actions (most common), GitLab CI, CircleCI, Jenkins, Buildkite, Drone. Career progression: Practitioner (basic workflows, 3-5 months, $85-110k) → Intermediate (multi-stage, parallelization, matrix builds, $110-150k) → Advanced (blue-green/canary, OIDC secrets, monorepo optimization, $150-200k). Pricing: most platforms free ≤ X job-minutes/month; GitHub Actions $0.008/minute overages.
什麼是 CI/CD Pipelines (Jenkins, GitLab CI, CircleCI)
CI/CD pipelines automate the journey from code commit to production: code is committed to version control, automatically built, tested, and deployed to staging/production without manual hand-offs. CI/CD eliminates the "works on my machine" problem and reduces deployment friction. Career paths: Practitioner (basic GitHub Actions/GitLab CI workflows, $85-110k) → Intermediate (multi-stage pipelines, parallelization, matrix builds, $110-150k) → Advanced (blue-green deployments, canary releases, OIDC secrets management, monorepo optimization, $150-200k+) over 5-6 months. Most modern teams use GitHub Actions (if on GitHub), GitLab CI (if on GitLab), or CircleCI. Jenkins remains dominant in enterprises. The skill is tactical and hands-on: you're writing YAML, debugging flaky tests, and optimizing build times. In 2026, CI/CD is foundational, teams without it ship slower and with more bugs.
