I’ve created an ssh keypair in my persistent user storage in the folder
~/.ssh/. This key was verified to work correctly and I was able to successfully make a commit and put on my github account, both from the command line and using the
However, when I logged out of JupyterHub and came back the next day and attempting to make a pull from the same repo, the
jupyterlab-git extension gave an error, notifying me that the keys were too permissive and it would not perform the indicated operation. After a little googling, I realized that the keys need to be set to 600 to ensure other users on the system do not have permission to access them. Nothing a little
chmod couldn’t handle, and I was back in business in no time. However, later in the day I realized that these permissions revert back to 660 upon every log in.
Are there any best practices for how to ensure these key permissions persist at 600 across sessions? I was thinking I could do something like:
singleuser: lifecycleHooks: postStart: exec: command: ["chmod", "600", "~/.ssh/id_rsa"] command: ["chmod", "600", "~/.ssh/id_rsa.pub"]
config.yaml but I wasn’t sure if there was a better way to accomplish this task, or what would happen if another user didn’t have these keys created. Any thoughts?
