Kubernetes（k8s）集群安装JupyterHub以及Lab

背景

JupyterHub 为用户组带来了笔记本的强大功能。它使用户能够访问计算环境和资源，而不会给用户带来安装和维护任务的负担。用户——包括学生、研究人员和数据科学家——可以在他们自己的工作空间中完成他们的工作，共享资源可以由系统管理员有效管理。

JupyterHub 在云端或您自己的硬件上运行，可以为世界上的任何用户提供预先配置的数据科学环境。它是可定制和可扩展的，适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/developer/article/1902519 创建动态挂载存储

第二步、安装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

1 2	root@hello:~# docker load -i pause-3.5.tar root@hello:~# docker load -i kube-scheduler.tar

第四步、安装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：此文件可以自定义内容，具体看注释，如下开启lab功能

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!
# #
# # Introduction to YAML:     https://www.youtube.com/watch?v=cdLNKUoMc6c
# # 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、修改svc为nodeport

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