Hello, I'm working on centreon-docker.

some people will say it's difficult.

but,  centreon in a docker allows me to quickly test the service easly.

 have carried out three types of deployment:

  1. all in one container
  2. container ( centreon + database)
  3. container (centreon + php + database)

Here's my dockerfile. I'm looking for distributors.

I'll send you more later.

what do you mean you are looking for distributors? is there going to be a:

 

centreon + apache + php + db?

centengine + gorgone + apache + php + db?

 

go on! looks fun!

Hi ponchoh,

I would like to make
container1: apache + centreon-*
container2: php-fpm
container3: mariadb

we still have a long way to go.

I am posting here in the hope of meeting people who are looking for the same things about “centreon docker” and who share their ideas.

I am not very familiar with the connections between Centreon Engine, Gorgoned and cbd.

have you looked into others? for example:

 

https://github.com/Tpo76/docker/tree/24.04-WIP/centreon

 

or

 

other?

The current centreon packages were designed to install Centreon on a server. They are not suitable for creating containers.
