Thanks for this! I had to change the last line to initctl restart jupyter-server in order for it to work.

Thanks for the feedback Robert. Glad it helps.
Yes, are you using an instance based on Amazon Linux 1 by any chance?
The Jupyter restart command is slightly different indeed. https://github.com/aws-samples/amazon-sagemaker-notebook-instance-customization#51-restart-jupyterlab

Thanks for this - that's an excellent addition!
In order to have a persistent configuration after stop/start actions on SageMaker Notebook Instances, I've added environment configuration:

'environment' : {'XDG_DATA_HOME' : '/home/ec2-user/SageMaker/<preferred subdir>'}

Could you also add the configuration so that it shows up within the JupyterLab environment?

Thanks your contribution @tbugfinder. I have added the configuration in the script. Great work!

This is great. Thank you @sofianhamiti.
Assuming 'environment' : {'XDG_DATA_HOME' : '/home/ec2-user/SageMaker/<preferred subdir>'} installs VS Code in Sagemaker's EBS, it should persist through restarts, no?

And if so, do I need to add this to Lifecycle Configuration?

@zburq that's correct yes. You extensions and setting will persist if you point XDG_DATA_HOME to a folder under /home/ec2-user/SageMaker/

You can add this script to a lifecycle config to automate the install between Stop/Start of the instance.
I personally just run the script when starting the instance, as it's very quick and simple to run.

@sofianhamiti sorry - I don't understand. If VSCode is installed in EBS, and persists even after restart, why do you run the script when you restart the instance?

Has anyone run into this error message

Failed to restart jupyter-server.service: The name org.freedesktop.PolicyKit1 was not provided by any .service files
See system logs and 'systemctl status jupyter-server.service' for details.

I've looked around and don't seem to be able to find a solution to this.

Replying to my own comment, it seems that simply running the final command w/ sudo allowed me to progress. Thanks for the solution.
