环境准备：k8s环境>=1.18

一、使用镜像suggest123/k8s-hub:0.0.11 此镜像使用jwt验证登录

之后可以教大家如何自定义一个jupyterhub镜像。

二.存储选择

1. localpath（本地存储）:

提供文件 local-path-storage.yaml。

apiVersion: v1
kind: Namespace
metadata:
  name: local-path-storage

---
apiVersion: v1
kind: ServiceAccount
metadata:
  name: local-path-provisioner-service-account
  namespace: local-path-storage

---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: local-path-provisioner-role
rules:
  - apiGroups: [ "" ]
    resources: [ "nodes", "persistentvolumeclaims", "configmaps" ]
    verbs: [ "get", "list", "watch" ]
  - apiGroups: [ "" ]
    resources: [ "endpoints", "persistentvolumes", "pods" ]

          volumeMounts:
            - name: config-volume
              mountPath: /etc/config/
          env:
            - name: POD_NAMESPACE
              valueFrom:
                fieldRef:
                  fieldPath: metadata.namespace
      volumes:
        - name: config-volume
          configMap:

                    "paths":["/opt/local-path-provisioner"]
            }
            ]
    }
  setup: |-
    #!/bin/sh
    while getopts "m:s:p:" opt
    do
        case $opt in
            p)
            absolutePath=$OPTARG
            ;;
            s)
            sizeInBytes=$OPTARG
            ;;
            m)
            volMode=$OPTARG
            ;;
        esac
    done

    mkdir -m 0777 -p ${absolutePath}

修改对应路径，具体想要了解的话可以去看下k8s的volumeMounts介绍。挂载卷

设置本地存储运行命令 kubectl apply -f .

      volumes:
        - name: export-volume
          hostPath:
            path: /data

修改对应路径

设置网络存储运行命令kubectl apply -f . 

三.部署jupyterhub

对应压缩包 jupyterhub.zip。 修改相应的jupyterhub-config.yaml文件（存储、资源、调度、自定义参数） jupyterhub_config.py为jupyterhub 程序运行参数。可以自定义设置。 部署命令，使用helm命令部署jupyterhub，helm版本>=v3.5.3

---

使用命令部署：helm upgrade --cleanup-on-fail \ --install jupyterhub ./jupyterhub-1.1.3.tgz \ --namespace jhub \ --create-namespace \ --values jupyterhub-config.yaml \ --set-file hub.extraFiles.my_config.stringData=jupyterhub_config.py
