OpenSearch on K8s: migrate from 2.7.0 to 2.8.0 or later version of the chart
Closed, DeclinedPublic
Actions

Description

Before we can support the latest versions of OpenSearch in dse-k8s, we'll need to migrate from version 2.7.0 to version 2.8.0 of the chart (see this compatibility matrix) . Note that the OpenSearch developers are hinting that version 3.0 of the chart might be released soon.

In order to do that, we need to:

  • T407123 Mirror the upstream OpenSearch Debian repos (see T403301 and related tickets)
  • Ensure we're not being affected by this permissions bug , which is what initially caused me to drop 2.8.0 and focus on 2.7.0. This will likely be fixed when the patch associated with T404874 is merged by the upstream opensearch-k8s-operator project,
  • T407125 Make the appropriate modifications to our OpenSearch helm charts
  • Ensure operation

Per this Slack conversation , we have decided against using deploying the 2.8.0 operator as we know the 2.7.0 version of the operator works. Long-term, we'll run the 3.x version of the operator (ref T414217 ☂️Test OpenSearch k8s Operator 3.x ☂️). Closing...
