Active Mq artemis hig availability and failover

[Adrija Basu <ad...@gmail.com>]

Hello Team

I am trying to setup high availability and failover of active mq artemis on
kubernetes cluster (minikube) I am using the Replication policy

HA Policy: Replicated and in my kubernetes yaml file I have mentioned
replica count as 3 so 3 pods are getting created 1 as master and 2 as
slaves however I am noticing only for 1 slave the logs is coming as "backup
announced" but for the second slave it is not coming like this as I am very
new to Artemis so I want to understand is it a 1:1 mapping I mean for one
liver server 1 backup server will be created? if it is so how to configure
to create 1 master and multiple slaves?

--Thanks And Regards

Hi, Adrija

I too have been working with trying to setup high availability and failover of active mq artemis on
kubernetes cluster.  The Live – Backup Groups section of this doc https://activemq.apache.org/components/artemis/documentation/latest/ha.html#high-availability-and-failover describes that only one backup server will announce as the backup.  The rest will be awaiting to become a backup server. If active server goes away then the backup server will go live and a server from the backup group will be selected to be the new backup server.
