Hi,

If you upgrade to Telepresence v0.58 this should be fixed natively.

Can I ask what you're using Telepresence for?

[vincentvanderweele]

Thanks!

I mean to use it to run my local code in a remote kubernetes cluster. So far I've been using a script to zip my source code, scp it to the cluster host, unzip, build a container, and add it to the cluster. It gets even more complicated when I want to debug the code remotely. Telepresence should make that all a whole lot easier.

I only started using it now but the first tests are promising!

Cool, let us know if you have any problems or features you'd like added. You might also be interested in http://forge.sh, another tool we're working on.
