Hello,
Any documentations please on building AWX HA Cluster with Redis ? Can’t see it no where 
I know it’s new (Redis has replaced RabbitMQ) but in case you have any tips or recommendations especially for the Redis part
thank you in advance 
As stated before:
Short answer is you don’t use redis to build the cluster, redis is unrelated to clustering. It’s now using postgres for inter-node communication.
For more information, see https://groups.google.com/d/msgid/awx-project/c2b636b7-e525-4955-817a-793fb43e4a48%40googlegroups.com?utm_medium=email&utm_source=footer
and https://github.com/ansible/awx/issues/5443.
If you are looking for help with an ‘AWX-HA-Cluster’ (or similar) project that you found on GitHub/reddit/etc, that is not part of the upstream AWX project, and you are best off asking the maintainers of those directly, as there’s no guarantee they’re on this list.
