GitLab CI/CD Tutorial: Zero to Pipeline in 20 Min

Description

Stop deploying manually. GitLab CI/CD lets you build, test, scan, and deploy your code automatically — right inside GitLab, no extra tools needed. This crash course takes you from zero to a full production pipeline in 20 minutes. 🔥 In this video, you'll learn: • What CI/CD actually means (CI vs CD vs Continuous Deployment) • How GitLab pipelines, stages, and jobs work • Writing your first .gitlab-ci.yml from scratch • GitLab Runners: shared, self-hosted, and Kubernetes • Variables & secrets — the safe way • Artifacts vs Cache — the difference explained simply • Environments: staging auto-deploy + manual production gate • Rules for controlling when jobs run • needs: to cut pipeline time in HALF (DAG pipelines) • Parallel & Matrix builds for cross-version testing • Built-in Security scanning: SAST, dependency scanning, secret detection • Top 10 GitLab CI/CD best practices ⏱️ Timestamps: 0:00 - Hook: Manual deployments must die 2:30 - What is CI/CD?
