Re: [Zabbix-users] Zabbix - Distributed installation over Docker

[Roberto C. <rob...@gm...>]

Dear all, at first I had only one server with Zabbix service, frontend
web and mysql. But when the quantity of hosts increased, the server
had performance problems and we decided to separate the solution into
three independent servers, and everything was OK.

Following the above criteria, I think it's a good practice to deploy
three independent servers, each one with docker and a container
(zabbix service, frontend web and mysql). We've decided to change to
Docker because we have testing and production environments, and we
have to enter the Docker world.

Is my idea ok? Or do you recommend to me just one Docker host and the
three containers on it? In this case, is there any risk of having
performance problems as I have in my first implementation as I told
you? Because we have a large quantity of hosts to monitor.

Special thanks !!!
