shell

#! /usr/bin/expect -f

# ssh into the vagrant coreos machine
spawn ssh coreos

# find a prompt inside the vagrant vm
expect "*core@core*"

# get a shell inside the docker container
send "sudo nsenter --target \$(docker inspect --format '{{.State.Pid}}' \$(docker ps | grep dex_server:latest | awk '{print \$1}')) --mount --uts --ipc --net --pid\r"

# find a prompt inside the docker container"
expect "*root*"

test

#! /usr/bin/expect

cd [ file dirname $argv0]

# get a shell in the server container
