Create an EBS volume

I want to create an EBS volume for my instance.  I can run the ec2 command to do this but when you need to do this task every other day, it can be a pain.  So, I wrote a bash script to make my life easier.

Prerequisite: Install the ec2 command line tool.  Follow the instructions from here.

You may need to change the region and url.  Anyways, here you go.

#!/bin/bash

export EC2_REGION=us-east-1

export EC2_URL=https://us-east-1.ec2.amazonaws.com

zone=us-east-1c

# Ask for size of volume to create

echo "Enter volume size between 10-1024 GB, then hit return"

read volume_size

echo "Validating value..."

if [[ $volume_size =~ ^[0-9]+$ ]]; then

  echo "..."

else

  echo "Value must be an integer"

  exit 1

fi

if (( $volume_size < 10 )) || (( $volume_size > 1024 )); then

  echo "Value must be between 10-1024 GB"

  exit 1

fi

#if (( $volume_size > 1024 )); then

#  echo "Value must be between 10-1024 GB"

#  exit 1

#fi

echo "Creating $volume_size EBS volume now..."

# create ebs volume

ec2-create-volume -s $volume_size -z $zone

echo "Request complete. Keep reference of volume id above"
