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 change region using --region.

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 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.

Use --sudo to run commands via sudo.

Use -i to specify a private key.
