Building/installing AWX for ARM64

NOTE: it seems that somebody else beat me to this, so I'm not going to finish this

https://qiita.com/ussvgr/items/81b88653b2845b0f1bea

Prerequisites:

  1. An ARM64 machine with Ansible and Docker installed to build the images on. This doesn't necessarily need to be the same machine that you're going to deploy AWX on. Considering using something like an AWS Graviton2-based EC2 instance to cut down on image build time
  2. A Docker registry to push the custom images to
  3. A Kubernetes cluster on ARM64 to deploy on

Custom ipaddress fact that ignores Docker (and other) interfaces
# The builtin ipaddress fact is very naive and will pick the IP address of the
# first (alphabetically) interface. This fact changes that behavior and only
# grabs the IP off an interface matching /^(eth|bond|vlan)\d/. This excludes
# interfaces types such as TUN, bridges, and Docker.
Facter.add("ipaddress") do
has_weight 100
setcode do
# This allows the fact to work from the commandline
