Hello @fwasdfw
That's a tricky question since we don't have documented procedure how to deploy Eclipse Che on disconnected Kubernetes cluster. We do have such a procedure for OpenShift only [1].

I would say that you need a private docker registry and you don't need any PostgreSQL DB. Here are yamls to deploy DevWorkspace and Che operators [2] [3]. Also you have to configure OIDC provider on the cluster.

@tolusha o, thank you！ so, should i need install the che-server in my k8s also ?

@fwasdfw Correct, you'll need to install the che-operator (I believe that's what you meant by che-server? or were you referring to the specific che-server component?), which manages deploying all of the components of Che with the exception of the DevWorkspace Operator, which you'll have to deploy yourself.
