Does Rundeck Enterprise Cluster Support Zero-downtime Upgrades?

[FHabash]

I reviewed the clustering and upgrade docs, but wasn't able to get a statement if RD EE support performing a rolling upgrade i.e. one node at a time. Because all cluster nodes share the same DB, looks like RD upgrade is a total outage event.

Can someone confirm, please. Any ideas on how to do zero or near-zero upgrades?

Thanks

Hi!

That's correct FHabash, all upgrade scenarios include some downtime because of the internal database changes (as you said, all members share the backend).

Regards!

Thank you.
