EC2 Management Script

A script to manage EC2 instances, in particular, to start/stop an instance, update the instance's SG ingress rules with your IP, and get the instance's state.

Configuration File

In order to use the script, you must populate a configuration file called .servers.

[rdp_server]
instance_id = <instance id>
region = ca-central-1
sg_id = <sg id>
range_description = Christopher home

[vpn_server]
instance_id = <instance id>
region = us-east-2
sg_id = <sg id>
range_description = Christopher

Actions

start

Start the instance, wait for it to go into running state, and then output the public DNS name.

./server start rdp_server
ec2-<ip>.ca-central-1.compute.amazonaws.com

stop

Stop the instance.

./server stop rdp_server

get_state

Output the instance's current state.

./server get_state rdp_server
stopped

update_sg_ingress

Scope all IP ranges with a description matching the description in the configuration file to your current public IP address, and then output the security group's ingress rules.

./server update_sg_ingress vpn_server
