Clusters & application replicas
Group registered servers, prepare K3s, and deploy supported applications with multiple replicas. Scale an active application using its existing image.
Cluster operations require a self-hosted or desktop controller and are unavailable on the hosted Cloud controller.
Open the guideHow it works
Connect selected servers over a verified private network, prepare the cluster runtime, and select it as the project destination. Setup has prerequisites, progress, and recoverable operations.
Set replicas for supported applications or workers and inspect ready pods and routing. Policy-driven autoscaling, automatic gateway failover, and Compose scaling through this application path are not implemented.
What you can do
Managed setup
Prepare networking and the runtime on registered servers.
Image reuse
Change replicas without rebuilding application source.
Observed state
Inspect ready replicas rather than just saved configuration.

Self-hosted and free, or managed on Openship Cloud — the same workflow either way.
