Volume mounts

Telepresence supports locally mounting of volumes that are mounted to your Pods. You can specify a command to run when starting the intercept, this could be a subshell or local server such as Python or Node.

shell
telepresence intercept <mysvc> --port <port> --mount=/tmp/ -- /bin/bash

In this case, Telepresence creates the intercept, mounts the Pod's volumes to locally to /tmp, and starts a Bash subshell.

Telepresence can set a random mount point for you by using --mount=true instead, you can then find the mount point in the output of telepresence list or using the $TELEPRESENCE_ROOT variable.

Terminal
$ telepresence intercept <mysvc> --port <port> --mount=true -- /bin/bash
Using Deployment <mysvc>
intercepted
Intercept name : <mysvc>
State : ACTIVE
Workload kind : Deployment
Destination : 127.0.0.1:<port>
Volume Mount Point: /var/folders/cp/2r22shfd50d9ymgrw14fd23r0000gp/T/telfs-988349784
Intercepting : all TCP connections
bash-3.2$ echo $TELEPRESENCE_ROOT
/var/folders/cp/2r22shfd50d9ymgrw14fd23r0000gp/T/telfs-988349784

With either method, the code you run locally either from the subshell or from the intercept command will need to be prepended with the $TELEPRESENCE_ROOT environment variable to utilitze the mounted volumes.

For example, Kubernetes mounts secrets to /var/run/secrets/kubernetes.io (even if no mountPoint for it exists in the Pod spec). Once mounted, to access these you would need to change your code to use $TELEPRESENCE_ROOT/var/run/secrets/kubernetes.io.
