We run Artemis in HA configuration under Kubernetes, with a primary and backup
instance that have shared storage. Recently, we updated our pod definitions
from version 2.30 to 2.39. And... something went wrong. I think what happened
is one of the two pods upgraded first, and our clients started getting
AMQ219010: Connection is destroyed errors. Restarting both Artemis pods made
everyone happy again.
It's too late to gather good post-mortem evidence, but this leads me to ask,
what is the recommended update procedure? Clearly, we can stop our own
services while Artemis is completely updated. But is there a recommended
interruption-free way to do it?
Thanks
