The problem:

I wanted to use the jinja 'map' filter to modify each item in a string, in this simple 
example, adding '.conf' to each item.

The 'format' filter in jinja takes arguments (value, *args, **kwargs).  Unfortunately, 
it uses 'value' as the pattern. When called inside map 'value' is the current item in 
the list, or in other words *args as far as format is concerned. So it's the wrong way 
around.

# Automated AMI Backups
#
# @author Robert Kozora <bobby@kozora.me>
#
# This script will search for all instances having a tag with "Backup" or "backup"
# on it. As soon as we have the instances list, we loop through each instance
# and create an AMI of it. Also, it will look for a "Retention" tag key which
# will be used as a retention policy number in days. If there is no tag with
# that name, it will use a 7 days default value for each AMI.

"""
Suspend an auto scaling group's scaling processes that can interfere with CodeDeploy deploys.
It assumes a single ASG per deployment group.

To use this:
* create a lambda function with this code, then hook up it up to an SNS topic that receives all deployment events (but not host events).
* attach that topic as a trigger in your deployment groups.

Unlike AWS's in-appspec approach, this supports arbitrary deploy concurrency.
