How to deploy zabbix on kubernetes with database replication

[mfuk]

HI morning,
I'm trying to deploy zabbix on kubernetes.
I'm using official containers (https://github.com/zabbix/zabbix), but I don't understand, how can create database replication.
I would deploy zabbix cluster with 3 zabbix servers (zabbix-server-0, zabbix-server1, zabbix-server-2) instances and each instances read/write from database a specific database pod, for example:

zabbix-server-0 -> zabbix-mysql-0
zabbix-server-1 -> zabbix-mysql-1
zabbix-server-2 -> zabbix-mysql-2

How can deploy it?
Thanks for the help

You want 3 server, you insstall 3 srvers... and 3 DB-s... There cannot be any replication between multiple working instances...

thanks for the reply.
Sorry I would create a zabbix cluster wirh 3 nodes, but how can replicate the db?

OK.. HA setup with 3 zabbix nodes.. that will work.
But for DB, you need to look up some additional tools, which manage HA DB and its replication. pg_auto_failover, patroni... there are probably some more... And then you want to make it even more complicated with adding a container layer..
Setting up DB engine is not part of Zabbix installation. Zabbix provides scripts and instructions, how to create tables etc... but how you set up your DB engine, as HA or not, is up to you...

Thanks for your reply.
That's why I posted it in the forum to ask other users how they solved it.

How did your project go? I am asking because someone at InitMax (they do Zabbix support) told me Zabbix does not do well in a Kubernetes environment. This kinda bummed me out as I figure a HA Zabbix Kubernetes deployment with a HA Galera DB cluster sounded likes the best deployment scenario (HA and scalability).

So would like to know how your project turned out, since the last update is a year old
