# then just edit the ~/.tmate.conf and set: 
# change tmate-server-port 22 
# to 
# tmate-server-port 2222
#
# if you have docker running on a VPS somewhere, change localhost to the ip of your VPS for: 
#
# tmate-server-host localhost
#
# to 
# 
# tmate-server-host aa.bb.cc.dd
#
# also upload the ~/tmate/ directory to the VPS user's home dir then run the docker command on the VPS: 

docker run -it --name my_tmate --restart always -d --cap-add SYS_ADMIN -v $HOME/tmate:/tmate:ro -e "SSH_KEYS_PATH=/tmate/keys" -e "SSH_PORT_LISTEN=22" -p 2222:22 tmate/tmate-ssh-server
