Multi-Cluster Deployment with ArgoCD

ArgoCD~25 minSenior

Your organization runs workloads across two KIND clusters: cluster-us and cluster-eu. Configure ArgoCD running on cluster-us to deploy the nginx-web application to both clusters simultaneously using an ApplicationSet with a cluster generator.

1Register cluster-eu as a target cluster in ArgoCD using argocd CLI

2Create an ApplicationSet manifest with a list generator targeting both clusters

3Verify nginx-web Deployment exists in namespace production on both clusters with 2 replicas

$argocd cluster add kind-cluster-eu --name cluster-eu
