What should I use for multi-cluster deployment?

It depends on what you mean by “multi-cluster deployment,” but in most Kubernetes environments the usual choices are:
If you want to deploy the same app to multiple clusters
Use a GitOps tool:
- Argo CD — very popular, great UI, strong multi-cluster support
- Flux — lighter-weight, very Kubernetes-native
If you want service discovery / traffic across clusters
Use a service mesh or multi-cluster networking solution:
- Istio or Linkerd for mesh-based approaches
- Submariner or cloud-native equivalents for cross-cluster networking
If you want centralized management of many clusters
Use a cluster management platform:
- Rancher
- OpenShift ACM
- Cloud-native options like Google Anthos, Azure Arc, AWS EKS Anywhere/management tools
Common recommendation
For most teams, a strong default is:
- Argo CD for deployment
- plus Helm or Kustomize for templating
- and a separate networking/mesh solution only if you need cross-cluster service communication
If you tell me:
- your platform (EKS/GKE/AKS/on-prem),
- how many clusters,
- whether you need active-active traffic or just deploy the same workloads,
…I can recommend the best specific stack.
