ArgoCD – GitOps Continuous Delivery

ArgoCD is a declarative, GitOps continuous delivery tool for Kubernetes. It automates application deployment by synchronizing desired state from Git repositories with the live cluster state.

Key Features

• GitOps: Git as single source of truth
• Auto Sync: Automatic deployment on changes
• Multi-Cluster: Manage multiple clusters
• RBAC: Fine-grained access control
• Web UI: Visual application management

Installation

Install ArgoCD on Kubernetes:

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

# Access UI
kubectl port-forward svc/argocd-server -n argocd 8080:443

Usage Examples

ArgoCD CLI operations:

# Login
argocd login localhost:8080

# Create application
argocd app create myapp \
  --repo https://github.com/org/repo.git \
  --path kubernetes \
  --dest-server https://kubernetes.default.svc \
  --dest-namespace default

# Sync application
argocd app sync myapp

# Check status
argocd app get myapp

Benefits

ArgoCD brings GitOps best practices to Kubernetes. Its declarative approach ensures consistency while the web UI provides visibility into deployment status.
