EcPc: Simple creation and managment of EC2 instances

EcPc provides a small collection of command-line tools to launch, list, log in to, and terminate EC2 (spot) instances.

It's deliberately a basic tool with few parameters for a user to tweak.

Prerequisites:

You need to have an AWS account, and have you ACCESS_KEY and SECRET_ACCESS_KEYs to hand. Then install boto3 according to the instructions here

Installation:

Via pip:

pip install ecpc

Usage:

To launch an instance, use ecpc create:

% ecpc create
creating a t2.small instance in region eu-west-1 with ID d830a8f4
key pair created
security group created
required ami identified
launching instance - this may take some time...
instance launched
%

You can give it a nicer name, change the instance type, and the region it is launched into:

% ecpc create -r us-west-1 -t c5.large -n c5large-1
creating a c5.large instance in region eu-west-1 with ID c5large-1
key pair created
security group created
required ami identified
launching instance - this may take some time...
instance launched
%

To list your instances:

% ecpc list
ID         region     type      up_time   state       cost($)
c5large-1  us-west-1  c5.large  00:00:00  booting-up  0.00   
d830a8f4   eu-west-1  t2.small  00:04:00  ready       0.00 

Note: the "cost" value is approximate

To log in to an instance, use ecpc login:

% ecpc login d830a8f4
