Creating 10 workers, takes the host ip using docker

run-workers.sh

#!/usr/bin/env bash

declare -i min=0
declare -i max=10

host=$(ip -4 addr show docker0 | grep -Po 'inet \K[\d.]+')

for (( c=min; c<max; c++  )) do
  echo "Going to start worker # $c"
  docker run\
    -e "DOCKER_HOST=$host"\
    -dit \
    --name "worker-$c"\
    local/worker:latest\
