Can we install the PAI based on existed k8s cluster?

[gemfield]

If so, where can find the document?

It is not tested by us. You can try it if you are interested:

1. Set up Kubernetes. We only test Kubernetes 1.14 and we enable RBAC in the cluster.
2. Set up a dev box container, as described in https://openpai.readthedocs.io/en/latest/manual/cluster-admin/basic-management-operations.html#pai-service-management-and-paictl
3. Set up services-configuration.yaml and layout.yaml Unfortunately, we don't have a convenient tool for this. Please check the source code under contrib/kubespray to find out how we generate these two files.
4. Put the two files in a <config-folder>, and update the config and start the service.

./paictl.py config push -p <config-folder> -m service
./paictl.py service start

@hzy46 Sounds plenty of work to do...may be I just wait for this feature comes in future :-)
