Deploying to multiple clusters

We learned how to register external clusters in the Configuring Argo CD against multiple clusters section. As soon as you have multiple external clusters registered to Argo CD, deploying an application to one of them is simple – you only need to refer to the external cluster you registered in the destination field of Argo CD’s Application. An example of this can be seen in the following manifest:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: clouds-app-dev-external-cluster
  namespace: openshift-gitops
spec:
  project: clouds-api
  source:
    repoURL: `https://github.com/PacktPublishing/OpenShift-Multi-Cluster-Management-Handbook'
    path: chapter10/clouds-api-gitops/overlays/dev
    targetRevision: dev
  destination:
    server: 'https://api.<external-cluster>:6443...
