+# This playbook coverts docker to go from loopback to direct-lvm (the Red Hat recommended way to run docker)
+# in AWS. This adds an additional EBS volume and creates the Volume Group on this EBS volume to use.
+#
+# To run:
+# 1. Source your AWS credentials (make sure it's the corresponding AWS account) into your environment
+# export AWS_ACCESS_KEY_ID='XXXXX'
+# export AWS_SECRET_ACCESS_KEY='XXXXXX'
+#
+# 2. run the playbook:
+# ansible-playbook -e 'cli_environment=<env-name>' -e "cli_volume_size=30" -e docker_loopback_to_direct_lvm.yml.yml
+#
+# Notes:
+# * By default this will do a 30GB volume.
+# * iops are calculated by Disk Size * 30. e.g ( 30GB * 30) = 900 iops
+# * This will remove /var/lib/docker!
+# * You may need to re-deploy docker images after this is run (like monitoring)
+#
