Simple scripts to launch EC2 instances
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.
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
% pip install ecpc
To launch an instance, use
% ecpc create my_instance creating a t2.small instance in region eu-west-1 with ID my_instance key pair created security group created required ami identified launching instance - this may take some time... instance launched use 'ecpc list' to follow launch progress %
You can change the instance type, and the region it is launched into:
% ecpc create my_c5 -r us-west-1 -t c5.large creating a c5.large instance in region us-west-1 with ID my_c5 key pair created security group created required ami identified launching instance - this may take some time... instance launched use 'ecpc list' to follow launch progress %
To list your instances:
% ecpc list ID region type up_time state cost($) my_c5 us-west-1 c5.large 00:00:00 booting-up 0.00 my_instance 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 my_instance Warning: Permanently added '126.96.36.199' (ECDSA) to the list of known hosts.

To transfer files and directories to/from your instance, use
% ecpc transfer my_local_directory my_c5:./ % ecpc transfer my_c5:./results/result.log .
To terminate an instance, use
% ecpc terminate my_instance instance terminated security group deleted key pair deleted .pem file deleted %
To create a new AMI based on the current state of an instance (e.g. after installation of a tailored software stack) use
% ecpc save my_instance -n my_provisioned_ami AMI my_provisioned_ami-5867234 being created Please do not terminate my_instance for ten minutes. %
Once ready, you can then launch a fresh instance based on this AMI:
% ecpc create my_provisiooned_p2 -t p2.xlarge -_n my_provisioned_ami creating a p2.xlarge instance in region eu-west-1 with ID my_provisioned_p2 key pair created security group created required ami identified launching instance - this may take some time... instance launched use 'ecpc list' to follow launch progress %
