docker - 部署 jupyterhub 时无法从 config.yaml 运行生命周期命令

Question

我想在创建 pod 并开始运行后立即运行命令。我正在部署 jupyterhub但我使用的配置是:

proxy:
  secretToken: "yada yada"
singleuser:
  image:
    # Get the latest image tag at:
    # https://hub.docker.com/r/jupyter/datascience-notebook/tags/
    # Inspect the Dockerfile at:
    # https://github.com/jupyter/docker-stacks/tree/master/datascience-notebook/Dockerfile
    name: jupyter/datascience-notebook
    # name: ${IMAGE}
    tag: 177037d09156
    # tag: latest
  lifecycle:
    postStart:
      exec:
        command: ["/bin/sh", "-c", "echo Hello from the postStart handler > /usr/share/message"]

当 pod 启动并运行时，我看不到文件 /usr/share/message因此，我推断 exec 命令没有运行。

使此命令起作用的正确方法是什么？

Answer 1

的正确键生命周期 节是 生命周期钩子(Hook) .

以下 blob 具有正确的值。

proxy:
  secretToken: "yada yada"
singleuser:
  image:
    # Get the latest image tag at:
    # https://hub.docker.com/r/jupyter/datascience-notebook/tags/
    # Inspect the Dockerfile at:
    # https://github.com/jupyter/docker-stacks/tree/master/datascience-notebook/Dockerfile
    name: jupyter/datascience-notebook
    # name: ${IMAGE}
    tag: 177037d09156
    # tag: latest
  lifecycleHooks:
    postStart:
      exec:
        command: ["/bin/sh", "-c", "echo Hello from the postStart handler > /usr/share/message"]
