FRP reverse proxy addon

Hi there.
I made a simple addon for hassio which is basically wrapper around frp client. But let me first give you small background why i decided to do it instead of using already existing solutions like autoSSH.
For that moment i don’t have wired connection and connect through 3g/4g modem. Connection is not stable at all and modem reconnects from time to time. Because of this problem autoSSH just got stuck and couldn’t connect to server again. I assume the issue could be with NGINX which always said that port in usage. So i stared to look at other projects and found really nice repository on github . Unfortunately i didn’t find existing addon for hassio so i created my own. It pretty simple, doesn’t support configuring through UI, doesn’t have prebuilt docker image, but it just works.
Here the link:

i will be appreciate for any feedback.
