Using jq to get+filter aws data

I've been playing with jq, and I've been having a hard time finding examples of how it works with output from a service like AWS (which I use a lot).

Here is one I use a lot with vagrant-ec2.

When we're launching and killing a lot of instances, the AWS API is the only way to track down which instances are live, ready, dead, etc.

To find instances that are tagged with e.g. {"Key" = "Name", "Value" = "Web-00'} in the middle of a vagrant dev cycle, or a prod launch/replace cycle, you can do something like this:

Getting latest tag on git repository
# The command finds the most recent tag that is reachable from a commit.
# If the tag points to the commit, then only the tag is shown.
# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object
# and the abbreviated object name of the most recent commit.
git describe
# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
git describe --abbrev=0

Blue-Green AWS Auto Scaling Deployments with Terraform

A quick note on how I'm currently handling Blue/Green or A/B deployments with Terraform and AWS EC2 Auto Scaling.

In my particular use case, I want to be able to inspect an AMI deployment manually before disabling the previous deployment.

Hopefully someone finds this useful, and if you have and feedback please leave a comment or email me.

Overview

I build my AMI's using Packer and Ansible.
