PostgreSQL streaming replication for Ansible Tower

 May 31, 2017

Ansible Tower 3.1 has recently been released, and it does implement real HA. In fact, up to version 3.0, Ansible Tower multi-node installation, only allowed a single machine to be primary and the switch was not possible in an automated fashion, so if the primary Ansible Tower would have collapsed, an operator should have promoted one of the secondary Ansible Tower to be primary to be able to carry on the work. With Ansible Tower 3.1 this is no longer the case, since all Ansible Tower machines are active all the time.
