背景

JupyterHub 为用户组带来了笔记本的弱小性能。它使用户可能拜访计算环境和资源，而不会给用户带来装置和保护工作的累赘。用户——包含学生、钻研人员和数据科学家——能够在他们本人的工作空间中实现他们的工作，共享资源能够由系统管理员无效治理。

JupyterHub 在云端或您本人的硬件上运行，能够为世界上的任何用户提供事后配置的数据迷信环境。它是可定制和可扩大的，实用于小型和大型团队、学术课程和大型基础设施。

第一步 、参考：https://cloud.tencent.com/dev… 创立动静挂载存储

第二步 、装置 helm

root@hello:~# curl https://baltocdn.com/helm/signing.asc | sudo apt-key add -
root@hello:~# sudo apt-get install apt-transport-https --yes
root@hello:~# echo "deb https://baltocdn.com/helm/stable/debian/ all main" | sudo tee /etc/apt/sources.list.d/helm-stable-debian.list
root@hello:~# sudo apt-get update
root@hello:~# sudo apt-get install helm

第三步 、导入镜像

root@hello:~# docker load -i pause-3.5.tar
root@hello:~# docker load -i kube-scheduler.tar

第四步 、装置 jupyterhub

helm repo add jupyterhub https://jupyterhub.github.io/helm-chart/


helm repo update


helm upgrade --cleanup-on-fail \
  --install ju jupyterhub/jupyterhub \
  --namespace ju \
  --create-namespace \
  --version=1.2.0 \
  --values config.yaml

注：此文件能够自定义内容，具体看正文，如下开启 lab 性能

root@hello:~# vim config.yaml
root@hello:~# cat config.yaml 
# This file can update the JupyterHub Helm chart's default configuration values.
# #
# # For reference see the configuration reference and default values, but make
# # sure to refer to the Helm chart version of interest to you!
# #

# # Chart config reference:   https://zero-to-jupyterhub.readthedocs.io/en/stable/resources/reference.html
# # Chart default values:     https://github.com/jupyterhub/zero-to-jupyterhub-k8s/blob/HEAD/jupyterhub/values.yaml
# # Available chart versions: https://jupyterhub.github.io/helm-chart/
# #
singleuser:
  defaultUrl: "/lab"
  extraEnv:
    JUPYTERHUB_SINGLEUSER_APP: "jupyter_server.serverapp.ServerApp"

#singleuser:
#  defaultUrl: "/lab"
#  extraEnv:
#    JUPYTERHUB_SINGLEUSER_APP: "notebook.notebookapp.NotebookApp"
root@hello:~# 
root@hello:~# 
root@hello:~#

第五步、批改 svc 为 nodeport

root@hello:~# kubectl get svc  -A
NAMESPACE     NAME                        TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)                  AGE
