+# This playbook creates an S3 bucket, if it doesn't already exist, and configures the docker registry service to use the bucket as its backend storage.
+# Usage:
+#  ansible-playbook s3_registry.yml -e bucketname="mybucket" -e accesskey="S3 aws access key" -e secretkey="S3 aws secret key" -e master="master fqdn or IP" -i "master,"
+#
+# Example:
+#  ansible-playbook s3_registry.yml -e accesskey="asdf" -e secretkey="hjkl" -e bucketname="testbucket" -e master="54.173.148.238" -i "54.173.148.238,"
+#
+# The bucket name can be anything, but generally should correspond with your cluster name.
+# The AWS access/secret keys should be the keys of a separate user (not your main user), containing only the necessary S3 access role.
+# The 'master' param is the fqdn or public IP of your cluster's master.
+# The -i param allows this playbook to be run on your master, even if it's not yet in your main inventory file. (The comma is mandatory).
