awsssh, pronounced osh, is an ssh configuration management tool for AWS EC2 instances. It uses boto to query for running instances and generates a valid ssh config entry for each instance.

awsssh will first read from ~/.awsssh.json, which is a json config of hosts and AWS keys, falling back to environment variables set for a single host using AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY to connect with boto.

Installation

awsssh can be installed easily via pip.

# Try this first in case you have write access to your default pip location
pip install awsssh

# If that fails because you are using your system python or something
sudo pip install awsssh

Usage

# Append new config data to the default ssh config
awsssh >> ~/.ssh/config

# Be way cooler about it by using a separate file
awsssh > ~/.ssh/configs/aws && sshconfig
# The above assumes such an alias for easily combining configs
alias sshconfig='> ~/.ssh/config && for f in ~/.ssh/config_*; do echo "# generated from $f" >> ~/.ssh/config && grep -hv ^# $f >> ~/.ssh/config; done'

Config

awsssh reads from an optional json config file describing hosts and their associated access key and secret. A sample config looks like

{
    "readability": {
        "keys": ["AMAZON_ACCESS_KEY", "AMAZON_SECRET_KEY"]
    },
    "secret_meat_project": {
        "keys": ["AMAZON_ACCESS_KEY", "AMAZON_SECRET_KEY"],
        "configs" : {
            "User": "ec2-user",
            "IdentityFile": "~/.ssh/some_key.pem"
        }
    }
}

Extra configs will get written to each host entry. There's no smarts in place for that just yet.

TODO

• Introduce a simple way to encrypt and decrypt the config data on the fly.
• Read from a boto config file if a user has one and no awssssh config.

Aliases

Some convenient aliases can be installed for satisfying s key smashing.
