Which deploy/s?

No response

Current Behavior

When we upgrade AWS RabbitMQ, all webserver containers (3 on PROD) might (does not happen always) break simultaneously leading to 404.

Expected Behavior

As long as AWS RabbitMQ has healthy Nodes, webserver containers should keep running

Steps To Reproduce

1. Upgrade RabbitMQ

Anything else?

We run Clustered (3 EC2 Nodes) AWS RabbitMQ. During upgrade 2 AWS RabbitMQ Nodes instances are available at all time (upgrade is applied to 1 Node at a time). Webserver containers should try to connect to different Nodes or reconnect to other Nodes if their connection went off.
