Kubernetes 上的 JupyterHub 不能剔除用户 Pod 失败

Question

我在 VMware 虚拟机上的本地 Kubernetes 集群上使用 Helm 图表实现了 JupyterHub。我想在用户闲置一段时间后剔除他们，但似乎行不通。

来自 hub pod（pod 名为

hub-545895f988-vmj2k

）的此错误日志可能与以下内容相关：

[W 2023-11-09 01:12:59.125 JupyterHub log:191] 403 GET /hub/api/users?state=[secret] ([email protected]) 6.40ms

• Kubernetes 版本 1.23
• Helm JupyterHub 图表版本 3.1.1
• JupyterHub 版本 4.0.2

这是我在 YAML 中的配置值：

singleuser:
  storage:
    capacity: 1Gi
    dynamic:
      storageClass: jhub-nas
  extraFiles:
    mountPath: /etc/jupyter/jupyter_notebook_config.json
    data:
      TerminalManager:
        cull_inactive_timeout: 300
        cull_interval: 60
      MappingKernelManager:
        cull_idle_timeout: 300
        cull_interval: 60
        cull_connected: true
        cull_busy: false

hub:
  service:
    type: LoadBalancer
  db:
    type: sqlite-pvc
    pvc:
      storage: 10Gi
      storageClassName: jhub-nas
cull:
  enabled: true
  timeout: 300 
  every: 60

我使用以下命令安装了该版本：

helm install jhub jupyterhub/jupyterhub -n jhub-ns --create-namespace --values config.yaml

我的项目也遇到同样的问题！我使用

kubectl cp jupyter-e928cdfb-2d2b2b-2d4441-2dae41-2d5e4f239780ea:/etc/jupyter/jupyter_notebook_config.json tmp.json

并从创建的容器中获取 jupyter_notebook_config.json 文件，看起来没问题。
