argocd deploying helm application using command line and yaml

You can deploy argocd helm application using the command line. This is when you wanted to use a git repo and specify a path

argocd app create helm-guestbook --repo https://github.com/argoproj/argocd-example-apps.git --path helm-guestbook --dest-namespace default --dest-server https://kubernetes.default.svc --helm-set replicaCount=2 

Or you can use the following yaml to deploy your sample helm application hosted in a git. (Not from a helm repo - for that you need to specify chart name). This is solely for deploying from a git source that contains helm deployment.

apiVersion: argoproj.io/v1alpha1

kind: Application

metadata:

  name: helm-guestbook

  namespace: argocd

spec:

  project: default

  directory:

      recurse: true

  source:

    repoURL: https://github.com/argoproj/argocd-example-apps.git

    path: helm-guestbook

    helm:

      releaseName: helm-guestbook

      parameters:

      - name: "replicaCount"

        value: "2"

      # valuesObject:

      #   replicaCount: 2 # didn't work for me

  destination:

    server: "https://kubernetes.default.svc"

    namespace: default

Then run the following command to create argocd application

argocd app create -f helm-local-deployment.yaml
