😽 kitten

Tiny multi-server automation tool.

It's designed to be as simple as possible and play nice with Unix tools.

Install

pip install kitten

Prerequisites

Kitten can get IP addresses from AWS resources for you. For that you'll need to have your AWS credentials set up. You can do that using awscli:

pip install awscli

Then:

aws configure

Examples

Get IP addresses 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 change region using --region.

By default private IP addresses are printed. Use --public if you prefer public IPs.

Run command on servers

$ kitten run uptime ubuntu 18.105.107.20 34.229.135.48
18.105.107.20	run	uptime
34.229.135.48	run	uptime
18.105.107.20	ok
34.229.135.48	ok
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.

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