Pairing is caring - Aldous Huxley
This repo is an attempt to build a pairing server using tmate and Alpine Linux. My main goal is to increase the amount of pairing teams do amongst each other. My implementation takes advantage of multi-stage container builds and Alpines awesomeness to generate container images just under 60MB. The other implementations of Tmate and Docker use Ubuntu as a base layer which produces containers upwards of 250MB+. I've tried to collate the tmate + docker approaches here, and have added a few other scripts + examples to make deploying tmate (and pairing) easier.
I didn't like how other implementations of tmate + docker cached the server keys into the docker container. This implementation will generate them when the container starts if they don't exist, and will use existing ones if it finds them. For this to work, you'll have to mount a volume into the container at /etc/tmate-keys so that your keys remain persistent through container restarts.
$ docker run --privileged -v tmate-keys:/etc/tmate-keys -e PORT=2222 -e HOST=127.0.0.1 -p 2222:2222 atomenger/tmate-docker:latest
TODO
Yes, Alpine Linux is missing backtrace and a few other constants from libbacktrace. To get around this, we patch out the use of it in tmate using backtrace.patch. See this link for more information and please feel free to correct me if my understanding of this is off.
I thank sigma for this patch and all other prior implementations of tmate on docker that I relied on.
