    SUBMARINE-478. Running jupyterlab container in KIND
    
    ### What is this PR for?
    Use jupyter's yaml file to run a jupyter container,
    1. First support mounting local path into jupyter
    2. Support setting jupyter password
    3. Run by creating jupyter pod in KIND
    4. Provide simple Python library support (if the submarine project has a 
relatively complete Python image, it can also be used)

+# Deploy Jupyter Notebook on Kubernetes
+This guide covers the deployment Jupyter Notebook on kubernetes cluster.
+
+## Experiment environment
+### Setup Kubernetes
+We recommend using [kind](https://kind.sigs.k8s.io/) to setup a Kubernetes 
cluster on a local machine.
+
+You can use Extra mounts to mount your host path to kind node and use Extra 
port mappings to port
+forward to the kind nodes. Please refer to [kind 
configuration](https://kind.sigs.k8s.io/docs/user/configuration/#extra-mounts)
+for more details.
+
+You need to create a kind config file. The following is an example :
+```
+kind: Cluster
+apiVersion: kind.x-k8s.io/v1alpha4
+nodes:
+- role: control-plane
+  extraMounts:
+  # add a mount from /path/to/my/files on the host to /files on the node
+  - hostPath: /tmp/submarine
+    containerPath: /tmp/submarine
+  extraPortMappings:
+  - containerPort: 80
+    hostPort: 80
+    protocol: TCP
+  # exposing additional ports to be used for NodePort services
+  - containerPort: 30070
+    hostPort: 8888
+    protocol: TCP
+```
+
+Running the following command:
+
+```
+kind create cluster --image kindest/node:v1.15.6 --config 
<path-to-kind-config> --name k8s-submarine
+kubectl create namespace submarine
+```
+
+### Deploy Jupyter Notebook
+Once you have a running Kubernetes cluster, you can write a YAML file to 
deploy a jupyter notebook.
+In this [example yaml](./jupyter.yaml), we use 
[jupyter/minimal-notebook](https://hub.docker.com/r/jupyter/minimal-notebook/)
+to make a single notebook running on the kind node.
+
+```
+kubectl apply -f jupyter.yaml --namespace submarine
+```
+
+Once jupyter notebook is running, you can access the notebook server from the 
browser using http://localhost:8888 on local machine.
+
+You can enter and store a password for your notebook server with:
+```
+kubectl exec -it <jupyter-pod-name> -- jupyter notebook password
+```
+After restarting the notebook server,  you can login jupyter notebook with 
your new password.
+
+If you want to use JupyterLab :
+```
+http://localhost:8888/lab
+```
