😽 kitten

Tiny tool to manage servers simultaneously. It aims to be as simple as possible.

Install

pip install kitten

Prerequisites

You'll need to have AWS credentials set up. You can do it using awscli:

pip install awscli
aws configure

Examples

Get IPs from AWS resources

Use kitten ip with either id, asg or elb:

$ kitten ip id i-04703bf3e6fab1926 i-07f234d0f29113ef2
18.135.117.17
24.129.235.48

$ kitten ip asg my-asg-name
18.105.107.20
34.229.135.48

You can select the region using --region.

Run command on servers

$ kitten run uptime ubuntu 18.105.107.20 34.229.135.48
18.105.107.20 uptime
34.229.135.48 uptime
18.105.107.20 17:11:48 up 1 day,  6:02,  0 users,  load average: 0.91, 2.99, 3.49
34.229.135.48 17:11:48 up 5 days, 11:19,  0 users,  load average: 6.34, 5.94, 5.72

Replace ubuntu with the user used to log in on the servers.

Commands are always run in parallel. Use --threads to specify the maximum number of concurrent connections (defaults to 10).

Use --sudo to run commands via sudo.

Use -i to specify a private key.

Get IPs and run command in one step

Just pipe the IPs from kitten ip to xargs:

$ kitten ip asg big-prod-asg-name | xargs kitten run 'rm -rf /tmp' root
