nickrw / ssh-ec2
Created March 3, 2015 17:04
ssh-ec2 - designed as an alias replacement of ssh. Will try and convert tags or instance IDs to IPs, and opens sessions in tmux if more than one result is returned
#!/bin/bash
try_ec2="$(resolve-ec2 $@)"
if [[ -z $try_ec2 ]]; then
ssh $@
else
if [[ $(echo "$try_ec2" | wc -l ) -gt 1 ]]; then
mux $1 $try_ec2
else
ssh $try_ec2

nickrw / mux
Created March 3, 2015 17:03
mux - takes a session name (optional) and list of hosts - then creates a new tmux session and opens SSH connections to the hosts in split panes
#!/bin/bash
ssh="ssh -o StrictHostKeyChecking=no"
function split_tmux() {
session=$1
shift
count=$(echo $@ | tr ' ' '\n' | wc -l)
echo "Starting session to $count hosts in $session: [$@]"
session="$session ($count)"

resolve-ec2 - turns command line parameters into IP addresses (Name tags or instance IDs). Intended to be used in conjunction with ssh-ec2 and mux
#!/usr/bin/env python
from boto import ec2
from functools import wraps
import re
def ip4(wrapped_func):
def _dec(request, *args, **kwargs):
response = wrapped_func(request, *args, **kwargs)
return [i.private_ip_address for i in response]
