For this tutorial Im using a public Github repo: $ gh repo create argotest --public --clone $ cd argotest Creating an umbrella Helm chart In our git repo we run: We create the Application manifest for our root is limited to deployment within a single cluster, making it more suitable for smaller-scale applications. For our case, well use the default in-cluster (where Argo CD itself is deployed). Because ArgoCD will overwrite the label with the Application name it might cause some selectors on the resources to stop working. We stream live every other Thursday at 3pm Eastern Time.
