CI/CD Pipeline for Zero Downtime Deployment (Real Setup) – What I Actually Use on My Client Projects
DevOps · 2026-04-20 · 32 min · Barthez Kenwou
Deploy multiple times a day without ever taking production down? Here's exactly the CI/CD pipeline I implement on all my environments in 2026: GitHub Actions for CI (build, test, scan, push), ArgoCD for GitOps, Argo Rollouts for Blue-Green or Canary with Prometheus analysis, feature flags, preview environments and automatic rollback. Fully expanded 2026 edition - what "zero downtime" actually means technically (probes, graceful shutdown, PodDisruptionBudget), the Expand-Contract pattern for database migrations finally explained, a dedicated section on configuration scenarios based on circumstances, real workflows, complete Rollout manifests, common mistakes, and a real case where we moved to multiple daily deployments with zero downtime.
