assh - select your servers from aws with ncurses and then ssh easily - or do something else with them.

How

assh brings a list of servers from your AWS account. Search, move, Hit enter to select one, then ssh (or whatever you want) to them.

Its extendible, so you can add some other commands - use it with fabric, ansible, ssh etc.

Why

Because servers come and go, and i started hating the questions "Do we have 2 appservers in X project or 3 ? ", "was it app4.x.project.com or app5.x.project.com".

Installation

use pip to install

pip install assh

then create a python file in your ~/.assh directory with somename

mkdir ~/.assh
vim ~/.assh/project.py

add your AWS account info

AWS_ACCESS_KEY_ID = 'XXXXX'
AWS_SECRET_ACCESS_KEY = 'YYYY'
AWS_REGION = 'us-east-1'

a region also can be a list eg AWS_REGION = ['us-east-1', 'us-east-2']

and then you can

assh project ssh

select your fav. server and hit enter.

you can also extend and override commands in project.py file

def cmd_SSH(self, line):
    return 'ssh -i ~/.ssh/project.pem ubuntu@%s' % line

for more examples about adding your own commands, please see http://github.com/ybrs/assh/examples/project.py

Usage

using fabric

assh project fab -P -- 'uptime && df -h'

assh project fab -P uptime

assh project ssh

assh project graph_cpu

you can also filter by tags

# show only worker instances - ones tagged with Role as worker
assh --filter-tag=Role:worker project ssh

# if we can only show one instance we don't show curses ui and jump directly to command
assh --filter-tag=Name:app1 project ssh

# because filtering with name is so common there is a shortcut
assh -N app1 project ssh

# we can pipe the servers name to another application with noop command
assh -N app1 project noop | xargs ssh -i ~/.ssh/foo.pem
