Spotr

Spotr simplifies launching, snapshotting and destroying AWS spot instances.

It's designed for users wanting to use a spot instance as a development box, and persist the state in between sessions.

Quick Start

First, install the library from pip or clone this git repository and install locally:

$ pip install spotr

$ pip install -e .

python -m build Next, set up credentials and region (in ~/.aws/config):

[default]
aws_access_key_id = YOUR_KEY
aws_secret_access_key = YOUR_SECRET
region=us-west-1

Then, launch an instance using:

$ spotr launch --type p2.xlarge --max-bid .30 --ami ami-4bf20033

List your running spotr instances with:

$ spotr list

When you're done working, you can save the current state (take a snapshot) using:

$ spotr snapshot

And then to terminate the instance:

$ spotr destroy

Next time you launch an instance, leave out the --ami tag and you'll restore the most recent snapshot taken with spotr.

$ spotr launch --type p2.xlarge --max-bid .30

You can specify default configurations in ~/.spotr/config:

[config]
max_bid=.30
type=p2.xlarge
ebs_optimized=true
security_group_id=sg-XXXXXXXXXXXXXXX
ami=ami-XXXXXXXXXXXXXXXX
us-west-2a_subnet_id=subnet-XXXXXXXX
us-west-2b_subnet_id=subnet-XXXXXXXX
us-west-2c_subnet_id=subnet-XXXXXXXX
us-west-2d_subnet_id=subnet-XXXXXXXX
iam_instance_profile_arn=arn:aws:iam::XXXXXXXX:instance-profile/instance-profile-role
hosted_zone_id=XXXXXXXXXXX
record_name=subdomain.example.com
user_data=#cloud-config

        - [ sh, -c, "/bin/bash /opt/dosomethinguseful.sh" ]
