Setting Up Argo CD With Helm Charts In Kubernetes

I am just playing around with Argo CD, To've more idea about GitOps with Argo CD, But I was having some challenges around the Ingress with ERR_TOO_MANY_REDIRECTS, I have to look at the Helm Values from the Github Repository – https://github.com/argoproj/argo-helm and then look more into some issues raised on Github – https://github.com/argoproj/argo-cd/issues/2953 and then I was able to successfully set it up.

How To Install Argo CD With Helm Charts

• Add the Argo CD Helm charts repo

  helm repo add argo https://argoproj.github.io/argo-helm

• Then install argocd, You can make use of this custom-override file by only changing the domain url and then the annotations to march your cluster config.

server:
  ingress:
    enabled: true
    annotations:
      kubernetes.io/ingress.class: nginx
      kubernetes.io/tls-acme: "true"
      cert-manager.io/cluster-issuer: letsencrypt
      cert-manager.io/acme-challenge-type: dns01
      cert-manager.io/acme-dns01-provider: cloudflare
    ingressClassName: ""
    hosts:
    - "argo.shehuawwal.com"
    paths:
    - /
    pathType: Prefix
    tls:
    - secretName: argo.shehuawwal.com
      hosts:
      - argo.shehuawwal.com
configs:
  params:
    server.insecure: "true"

• You can save the above file as argo-custom-override.yaml.
• Install argo with the override file

helm upgrade --install argocd argo/argo-cd --namespace argocd --create-namespace -f argo-custom-override.yaml

• You can then check to see if all pods are running. As you can see all pods are running below.

$ kubectl -n argocd get pods
