Access home directories of users of a hub

Sometimes, it is necessary to access the NFS home directories of users on a hub. Perhaps they’ve modified a dotfile (like .bash_profile or .bashrc) that prevents their server from starting, or we need to archive a large file there.

Sample notebook log from non-starting pod due to a dotfile that doesn’t have correct PATH:w

/srv/start: line 23: exec: jupyterhub-singleuser: not found

The exec homes subcommand of the deployer can help us here.

export CLUSTER_NAME=<cluster-name>
export HUB_NAME=<hub-name>

deployer exec homes $CLUSTER_NAME $HUB_NAME

Will open a bash shell with all the home directories of all the users of $HUB_NAME in $CLUSTER_NAME mounted in read-write fashion under /home/.
