ArgoCD / GitOps Setup

Implement GitOps with ArgoCD — declarative deployments, automatic sync, and drift detection for your Kubernetes workloads.

Overview

GitOps flips the deployment model: instead of your CI pipeline pushing changes into the cluster, ArgoCD continuously reconciles the cluster state against what's declared in Git. The result is a cluster that's always auditable, easy to roll back, and resistant to manual kubectl drift.

I set up ArgoCD properly the first time — app-of-apps structure, multi-environment promotion, and sync policies that match how your team actually ships code.

What's Included

  • ArgoCD installation & configuration — HA-ready install with RBAC scoped to your team structure
  • App-of-apps pattern — a single source of truth for what's deployed across your clusters
  • Multi-environment promotion — a clear path from dev to staging to production via Git, not manual approval clicks
  • SSO integration — ArgoCD access tied to your existing identity provider (Okta, Google, GitHub, etc.)
  • Rollback & sync policies — automated sync where it's safe, manual approval gates where it isn't

Our Process

  1. Environment & repo review — how your manifests/Helm charts are currently structured and deployed.
  2. GitOps design — repo structure, app-of-apps layout, and promotion strategy proposal.
  3. Implementation — ArgoCD deployed and connected to your Git repos, validated with a real application end-to-end.
  4. Handover — walkthrough of how to add new applications and how rollbacks work in practice.

Who This Is For

Teams already on Kubernetes who are deploying via kubectl apply or CI-triggered helm upgrade and want a proper audit trail, drift detection, and a real rollback story.

FAQ

Does this replace our existing CI pipeline? No — CI still builds and tests. ArgoCD takes over the deploy step, watching Git instead of your pipeline pushing to the cluster directly.

What if we manage multiple clusters? ArgoCD supports multi-cluster deployment from a single control plane, which is part of the standard setup if you have more than one cluster.

Is this compatible with Helm and Kustomize? Yes, both are supported as sources — we'll use whichever your manifests are already in, or migrate as part of the engagement if that's useful.
