I want to run a command as soon as a pod is created and starts running. I am deploying jupyterhub but the config that I am using is:
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"]When the pod is up and running, I am not able to see the file /usr/share/message and hence, I deduce that the exec command is not running.
What is the right way to make this command work?
The correct key for lifecycle stanza is lifecyleHooks.
Following blob is with the correct values.
