I korthet

GitOps treats Git repository as the single source of truth for infrastructure and applications. Tools: ArgoCD, Flux, Kustomize, Helm. A change to Git automatically triggers deployment via controller. Enables rollback (revert commit), audit trail, declarative desired state. Senior GitOps engineers earn $160-230k because they eliminate manual deploys and reduce outages. Used by unicorns (Shopify, Datadog, etc.). Mastery: 6-10 weeks.

Vad är GitOps Continuous Deployment

GitOps is an operational framework where Git is the single source of truth for infrastructure and application state. Instead of imperative deploys (manual kubectl apply, scripts), teams push Kubernetes manifests to Git. A GitOps controller (ArgoCD, Flux) continuously reconciles the cluster state with the Git repository. Any drift is corrected automatically. Key principles: (1) declarative (describe desired state), (2) versioned (Git history), (3) pulled (controller pulls from Git, not pushed), (4) automated (reconciliation loops). Rollback = revert Git commit.

❓ Vanliga frågor

What's the difference between GitOps and traditional CI/CD?
Traditional CI/CD: push code → pipeline builds → pipeline deploys. GitOps: push manifests to Git → controller automatically reconciles cluster state. GitOps is pull-based, declarative, auditable.
What's the difference between ArgoCD and Flux?
ArgoCD: UI-based, easier onboarding, good for multi-team. Flux: CLI-based, lightweight, GitOps-first philosophy. Both work well; choose based on team preference.
How do I rollback with GitOps?
Revert commit in Git. Controller automatically syncs cluster to previous state. Fast, auditable rollback (minutes, not hours).
How do I handle secrets in GitOps?
Never store plain secrets in Git. Use encrypted secrets (Sealed Secrets, SOPS, External Secrets Operator). Git stores encrypted; controller decrypts at runtime.
Can I use GitOps for non-Kubernetes deployments?
Yes, but niche. GitOps shines with Kubernetes. For VMs, use Terraform instead (also declarative and Git-based).
