Simple Guide: Install Argo CD in Kubernetes
1. Create a Namespace for Argo CD
kubectl create namespace argocd
2. Install Argo CD
Apply the Argo CD manifest in the argocd namespace:
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
kubectl create namespace argocd
kubectl apply -n argocd --server-side --force-conflicts -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
kubectl port-forward svc/argocd-server -n argocd 8080:443
kubectl get secret argocd-initial-admin-secret -n argocd -o json | jq -r ".data.password" | base64 -d
3. Access the Argo CD UI
Option 1: Port Forwarding
Expose the Argo CD API server locally:
kubectl port-forward svc/argocd-server -n argocd 8080:443
# or
kubectl patch svc argocd-server -n argocd -p '{"spec": {"type": "NodePort", "ports": [{"port": 80, "targetPort": 8080, "nodePort": 30080}, {"port": 443, "targetPort": 8081, "nodePort": 30443}]}}'
# or
# Access Argo CD Over NodePort (Create One More Service Specifically for NodePort)
apiVersion: v1
kind: Service
metadata:
name: argocd-server-nodeport
namespace: argocd
spec:
type: NodePort
selector:
app.kubernetes.io/name: argocd-server
ports:
- name: https
port: 443
targetPort: 8080
nodePort: 30101
Option 2: Ingress (Optional)
If you prefer external access, set up an ingress with your domain.
4. Log In to Argo CD
-
Get the initial admin password:
kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d; echo
-
Login to the Argo CD UI:
- Username:
admin
- Password: [Use the password from above]
5. Deploy Your First Application
- Connect your Git repository from the Settings > Repositories in the Argo CD UI.
- Create a new application by specifying:
- Application Name
- Repository URL
- Target Namespace and other settings.
Argo CD will deploy the application to your Kubernetes cluster.
