afssh

#!/bin/bash

directory=~/projects/php-nginx-wp-ansible

if [[ "$2" != "dbservers" && "$2" != "webservers" ]]; then
  echo ""
  echo "$2 is not a valid type. Pass either dbservers or webservers"
  exit
fi

ips=$(ansible-inventory -i $directory/inventories/$1 $2 --graph | grep "|--" | sed "s/  |--//g" | tr '\n' ' ' )

IFS=' ' read -r -a array <<< "$ips"

if [[ ${#array[@]} > 1 && -z ${3+x} ]]; then
  echo ""
  for key in "${!array[@]}"; do
      printf "%-8s\n" "${key}) ${array[$key]}"
  done
  echo ""
  echo "Select an index to ssh to (0-indexed): "

  read $3
fi


ip="${array[$3]}"


if [[ -z "$TUNNEL" ]]; then
  echo "SSHing to ${ip}"
  echo ""
  sleep 1
  clear
  ssh git@$ip
else
  echo ""
  echo "Tunneling to ${ip} on port ${TUNNEL}..."
  ssh -N -S none -L $TUNNEL:127.0.0.1:$TUNNEL git@$ip
fi

$ afssh production_nl webserver
$ TUNNEL=3306 afssh production_nl dbservers
$ afssh production_us webservers # Will show a list of IPs you can ssh to
