Preliminary

  • Kubernets has installed, if not check 🔗link
  • Helm binary has installed, if not check 🔗link

1. install argoCD binary

2. install components

2. Install argoCD
​
helm install argo-cd argo-cd \
  --namespace argocd \
  --create-namespace \
  --version 8.1.2 \
  --repo https://aaronyang0628.github.io/helm-chart-mirror/charts \
  --values argocd.values.yaml \
  --atomic

helm install argo-cd argo-cd \
  --namespace argocd \
  --create-namespace \
  --version 8.1.2 \
  --repo https://argoproj.github.io/argo-helm \
  --values argocd.values.yaml \
  --atomic

by default you can install argocd by this link

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

Or, you can use your won flle link.

4. prepare argocd-server-external.yaml

Install By
​
kubectl -n argocd apply -f - <<EOF
apiVersion: v1
kind: Service
metadata:
  labels:
    app.kubernetes.io/component: server
    app.kubernetes.io/instance: argo-cd
    app.kubernetes.io/name: argocd-server-external
    app.kubernetes.io/part-of: argocd
    app.kubernetes.io/version: v2.8.4
  name: argocd-server-external
spec:
  ports:
  - name: https
    port: 443
    protocol: TCP
    targetPort: 8080
    nodePort: 30443
  selector:
    app.kubernetes.io/instance: argo-cd
    app.kubernetes.io/name: argocd-server
  type: NodePort
EOF
​
kubectl -n argocd apply -f - <<EOF
apiVersion: v1
kind: Service
metadata:
  labels:
    app.kubernetes.io/component: server
    app.kubernetes.io/instance: argo-cd
    app.kubernetes.io/name: argocd-server-external
    app.kubernetes.io/part-of: argocd
    app.kubernetes.io/version: v2.8.4
  name: argocd-server-external
spec:
  ports:

    nodePort: 30443
  selector:
    app.kubernetes.io/instance: argo-cd
    app.kubernetes.io/name: argocd-server
  type: NodePort

---


EOF

5. create external service

kubectl -n argocd apply -f argocd-server-external.yaml

6. [Optional] prepare argocd-server-ingress.yaml

Before you create ingress, you need to create cert-manager and cert-issuer self-signed-ca-issuer, if not, please check 🔗link

Install By
​
kubectl -n argocd apply -f - <<EOF
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: argo-cd-argocd-server
  annotations:
    cert-manager.io/cluster-issuer: self-signed-ca-issuer
    nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
  ingressClassName: nginx
  tls:
  - hosts:
      - argo-cd.ay.dev
    secretName: argo-cd.ay.dev-tls
  rules:

    http:
      paths:
      - path: /?(.*)
        pathType: ImplementationSpecific
        backend:
          service:
            name: argo-cd-argocd-server
            port:
              number: 80
EOF
​

            port:
              number: 80

7. [Optional] create external service

kubectl -n argocd apply -f argocd-server-external.yaml

8. get argocd initialized password

kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d

9. login argocd

​
ARGOCD_PASS=$(kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d)
MASTER_IP=$(kubectl get nodes --selector=node-role.kubernetes.io/control-plane -o jsonpath='{$.items[0].status.addresses[?(@.type=="InternalIP")].address}')
argocd login --insecure --username admin $MASTER_IP:30443 --password $ARGOCD_PASS

if you deploy argocd in minikube, you might need to forward this port

ssh -i ~/.minikube/machines/minikube/id_rsa docker@$(minikube ip) -L '*:30443:0.0.0.0:30443' -N -f
open https://$(minikube ip):30443

if you use ingress, you might need to configure your browser to allow insecure connection

kubectl -n basic-components get secret root-secret -o jsonpath='{.data.tls\.crt}' | base64 -d > cert-manager-self-signed-ca-secret.crt
open https://argo-cd.ay.dev
