How to Set Up ArgoCD for GitOps Deployments

Setting Up ArgoCD for GitOps Deployments

ArgoCD is a declarative GitOps continuous delivery tool for Kubernetes. It monitors your Git repositories and automatically synchronizes your cluster state to match the desired configuration defined in code.

Install ArgoCD

Deploy ArgoCD into your Kubernetes cluster on your Breeze:

kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

Access the Dashboard

Expose the ArgoCD server and retrieve the initial admin password:

kubectl port-forward svc/argocd-server -n argocd 8080:443
argocd admin initial-password -n argocd

Connect a Git Repository

argocd login localhost:8080
argocd repo add https://github.com/your-org/k8s-manifests.git \
  --username git --password your_token

Create an Application

argocd app create my-app \
  --repo https://github.com/your-org/k8s-manifests.git \
  --path apps/my-app \
  --dest-server https://kubernetes.default.svc \
  --dest-namespace production \
  --sync-policy automated \
  --auto-prune \
  --self-heal

Key Features

• Automated Sync -- detects Git changes and applies them
• Self-Healing -- reverts manual cluster changes to match Git
• Auto-Prune -- removes resources deleted from Git
• Rollback -- instantly revert to any previous Git commit

ArgoCD provides a powerful web UI for visualizing application state, sync status, and resource health across all your deployments.
