EBS and EFS Volumes with Docker For AWS using REX-Ray

This procedure will deploy Docker For AWS and go through the steps to build REX-Ray containers. This process will have some hiccups because Docker for AWS will provision resources in different availability zones (AZs). Multiple workers/agents will be spread across AZs (not regions) which means a potential host failure will trigger Swarm to restart containers that could spread across an AZ. If a container is restarted in a different AZ, the pre-emption mechanism for REX-Ray will not work because it no longer has access to the volume in the former AZ.

Deploy Docker for AWS.

I have found this interesting for debugging, but also fun to hear web pages

"""
Copies all keys from the source Redis host to the destination Redis host.
Useful to migrate Redis instances where commands like SLAVEOF and MIGRATE are
restricted (e.g. on Amazon ElastiCache).

The script scans through the keyspace of the given database number and uses
a pipeline of DUMP and RESTORE commands to migrate the keys.

Requires Redis 2.8.0 or higher.
