Description

The OpenSearch service at CERN has been operating since 2016 on puppet-managed servers.

Currently managing 122 OpenSearch and OpenDistro clusters powered by a pool of 156 powerful physical machines running AlmaLinux 9.

In the current architecture, multiple clusters live within the same host, resources isolation (e.g., cpu, ram) is achieved on the process level and disk space is managed with LVM. This deviates from the standard OpenSearch deployment.

The objective of this project is to get familiar and explore a containerized deployment of OpenSearch using the standard Docker + Kubernetes images on the CERN IT Kubernetes Service.
