Tmate.io docker server
Run it as a priviledged image, as tmate requires some special capabilitites: CLONE_NEWIPC and CLONE_NEWNET
If you want to build it:
docker build -t teamwire/tmate .
This container will generate host keys during startup. If you need persistent host keys, map a host directory into the container.
If you want to use it, and you build it:
docker run --privileged -p 2222 -v /path/to/key/directory:/etc/tmate-keys -t teamwire/tmate
To know which port was tmate bound to, run:
docker ps # this will show you the container id
docker port <container id> 2222
By default tmate-docker will bind inside the container on port 2222. This means that the ssh command that tmate will give you will include that port.
Sometimes you want to run on a different port. To do that you need to set the PORT environment variable, this will be the one that tmate will bind to inside the container.
In a similar manner, the advertised hostname to connect to can be
changed with the HOST environment variable. By default, the docker
container name is used.
For example:
docker run --privileged -e HOST=example.com -e PORT=443 -p 443:443 -v /path/to/key/directory:/etc/tmate-keys -t teamwire/tmate
