=============================== 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:

.. code-block:: sh

$ pip install spotr

.. code-block:: sh

$ pip install -e .

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

.. code-block:: ini

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

Then, launch an instance using:

.. code-block:: sh

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

List your running spotr instances with:

.. code-block:: sh

$ spotr list

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

.. code-block:: sh

$ spotr snapshot

And then to terminate the instance:

.. code-block:: sh

$ spotr destroy

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

.. code-block:: sh

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

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

.. code-block:: ini
