Pre-requisites

• Python 3
• Boto3: pip install boto3
• An AWS account

Setting up:

• Create a role at https://console.aws.amazon.com/iam/home?region=us-west-1#/roles with the permission AmazonSQSFullAccess. This role also needs to named instance.
• Create a group at https://console.aws.amazon.com/iam/home?region=us-west-1#/groups with the permissions AmazonEC2FullAccess, AmazonSQSFullAccess and IAMFullAccess
• Create an user at https://console.aws.amazon.com/iam/home?region=us-west-1#/users with belonging to the group you've just created.
• Place the AWS credentials that were just generated in ~/.aws/credentials, the file should look like this:

[default]
aws_access_key_id=...
aws_secret_access_key=...

region=us-west-1

(notice the region=us-west-1 which is necessary, although you can edit instance.py on line 7 to match your desired region if wanted)

• Run client.py with parameters -n and -d
• Sit back and enjoy :)
