Installation of OpenSearch with Graylog 5.x (CentOS/Rocky Linux)

in CentOS installation and CentOS installation you write

sudo yum install -y opensearch

But this will break the installation, since (at the moment) version 2.9 is actual, but GL only supports OS up to 2.5.
The correct line would be

sudo dnf install opensearch-2.5.0

Can you correct this in the docs?

Greetings! Later version are compatible and do work. This is a mismatch with our docs unfortunately. I can conform that i’m running OpenSearch 2.8.0 without issue. I’ve also asked our internal teams and they have used 2.9.0 with success.

Hope that helps.

any inputs GL 5.2 with Opensearch 2.11 ?

As far as I’m aware all versions of OpenSearch 2.x are compatible, including 2.11.

Anecdotally, I’m running 2.11 and have not encountered any issues and have not found any issues or errors in the OpenSearch logs.
