Simple EC2 Management Script
This is a simple script to manage existing EC2 instances on AWS.
Requirements
Ruby >= 2.3 & Bundler 2.2.32
You have to set up your AWS credentials as described in the official documentation
Alternatively you can initialize @client with access_key_id, secret_access_key and region:
@client = Aws::EC2::Client.new(access_key_id: 'ACCESSKEY', secret_access_key: 'SECRET', region: 'eu-north-1')
Install gems
gem install bundler:2.2.32
bundle install
Usage
$ ruby ec2.rb -h
Simple EC2 Management.
Usage:
ec2 list [--verbose] [-r | -s]
ec2 describe <instance_id>
ec2 (start | stop | reboot | terminate) <instance_id> [--dry-run]
ec2 -h | --help
ec2 --version
Options:
-h --help Show this screen.
-r, --running Show only running instances.
-s, --stopped Show only stopped instances.
--dry-run Checks whether you have the required permissions for the action, without actually making the request.
--verbose Verbose output
-v, --version Show version.
Example usage:
$ ruby ec2.rb list
Instances: 5
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#1
Instance ID: i-123456789
Name: instance_name
State: STOPPED - Reason: Client.UserInitiatedShutdown
Private IP address: 0.0.0.0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
...
$ ruby ec2.rb start i-123456789 --dry-run
Attempting to start instance 'i-123456789' (this might take a few minutes)...
Check permissions to perform this operation: Request would have succeeded, but DryRun flag is set.
