Submarine Sandbox

Currently, we need to install kubectl, helm, java, maven, kind or minikube when new users try to install Submarine on the local machine. https://submarine.apache.org/docs/

We could leverage https://github.com/rancher/k3d  to install k8s and all other dependencies in a single docker file so that we could use one command (like docker run -p 32080 32080 apache/submarine-sandbox:latest)to launch the entire submarine cluster. In addition, k3d is more lightweight than minikube and kind.

This feature will be very useful for development and testing in the future.
