ploy_ec2 2.0.0b1
Plugin for ploy to provision Amazon EC2 instances.
License: BSD 3-Clause License

Overview
========

The ploy_ec2 plugin provides integration of `Amazon EC2`_ with `ploy`_.

.. _Amazon EC2: http://aws.amazon.com/ec2/
.. _ploy: https://github.com/ployground/


Installation
============

ploy_ec2 is best installed with easy_install, pip or with zc.recipe.egg in a buildout.


Masters
=======

To use ploy_ec2 you need an Amazon account and `AWS keys <http://docs.aws.amazon.com/general/latest/gr/getting-aws-sec-creds.html>`_.

Once you got your keys, you should put them in a secure location and reference them in your ``ploy.conf``.
Additionally you need to set the region of the master::

    [ec2-master:ec2eu]
    access-key-id = ~/.aws/ec2.id
    secret-access-key = ~/.aws/ec2.key
    region = eu-west-1

You can also set the ``AWS_ACCESS_KEY_ID`` and ``AWS_SECRET_ACCESS_KEY`` environment variables instead.

You need to define a master for each `region <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html>`_ you want to use.


Instances
=========

Each instance has the following mandatory settings:

``image``
  The `Amazon Machine Image (AMI) <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AMIs.html>`_ that this instance will start up with.

``keypair``
  The name of the `SSH keypair <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-key-pairs.html>`_ to use.

``placement``
  The `availability zone <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html>`_ in which to launch the instances.

``securitygroups``
  The name of the `Securitygroups`_ this instance should be assigned to.

The following settings are optional:

``instance_type``

``ip``

``startup_script``
  Path to a script which will be run right after creation and first start of the instance.
  This uses the `User Data <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/user-data.html>`_ feature and needs to be supported by the AMI.

``volumes``

``snapshots``

``device_map``

``delete-volumes-on-terminate``


Securitygroups
==============

``description``

``connections``
  ::

    [ec2-securitygroup:app-server]
    description = The production server
    connections =
        tcp     22      22      0.0.0.0/0
        tcp     80      80      0.0.0.0/0


Volumes
=======

You can define volumes via ``ec2-volume`` sections.
The id of the section must not start with ``vol-``.
You can declare the ``size`` as a number of GB.

If the volume doesn't exist, it is automatically created.

::

  [ec2-volume:a-volume-name]
  size = 100

  [ec2-instance:foo]
  ...
  volumes = a-volume-name /dev/sdf


Macro expansion
===============

For instances the ``ip`` and ``volumes`` options aren't copied when expanding macros.


Fingerprint verification
========================

Automatic ssh fingerprint verification works by checking whether the fingerprint is in the console output of the instance.

After reboot or stop/start of an instance, the console output is refreshed.
The problem with that is, that the fingerprint isn't included in the console anymore by default.
To fix that you need to log the fingerprint on reboot somehow.
One way to do that with Ubuntu is to add a script at ``/var/lib/cloud/scripts/per-boot/ssh-keys`` with this content:

.. code-block:: sh

    #!/bin/sh
    /usr/bin/ssh-keygen -l -f /etc/ssh/ssh_host_rsa_key.pub

Make sure that script is executable.
