awsh

Another SSH utility for AWS

Installation

$ pip install awsh

If you never configured awscli before.

$ aws configure

Alternatively it can be downloaded on pypi.

Requirements

• Python 2 or 3

What does it do?

It gives you a list of hosts you have access to and preconfigure ssh with the proper key and user (assuming they have not been overridden by a configuration management tool). You can filter by instance name and if it matches only one instance it will log to it.

Use Cases

• You are running Elasticbeanstalk, EMR or something that creates it's own instance automatically.
• You are using different key-set for different instances and you can't remember which one does what.
• Instances are coming and going and you lost track of what is available.

Usage

usage: awsh [-h] [--users USERS [USERS ...]] [--region REGION]
                   [-i KEY_PATH] [-c COMMAND] [-r REMOTE_HOST]
                   [-p REMOTE_PORT] [-l LOCAL_PORT] [--keys KEYS]
                   [--timeout TIMEOUT] [--console-output] [--version]
                   [filter]

SSH into AWS instances. The default user list assumes that your instances runs
on Ubuntu and or Amazon's AMIs. ex: "awsh --users user1 user2 --region us-
west-2 --keys '~/.keys' instance-name". Note that "awsh --users user1 user2
instance-name" will not be parsed properly due to the nature of nargs. In that
case you may want to do: "awsh instance-name --users user1 user2".

positional arguments:
  filter                Optional name filter. If only one instance is found,
                        it will connect to it directly.
