2.14.0 release highlights

Known issue

Users who have defined a custom readiness probe for Elasticsearch 8.2.0 or later will have to either remove the custom readiness probe before upgrading to 2.14 or if that is not possible have adjust the readiness probe script as follows after the upgrade:

podTemplate:
  spec:
    containers:
    - name: elasticsearch
      readinessProbe:
         exec:
           command:
           - bash
           - -c
           - /mnt/elastic-internal/scripts/readiness-port-script.sh

New and notable

New and notable changes in version 2.14.0 of {n}. Check [release-notes-2.14.0] for the full list of changes.

Custom transport certificate management

Starting with ECK 2.14.0 it becomes possible to fully delegate the transport certificate management for Elasticsearch to a third party component. When used in conjunction with the cert-manager operator and its CSI driver it also improves the scalability of node sets. Refer to the [{p}-transport-third-party-tools] for a complete example.

Advanced readiness probe

The Elasticsearch containers are now configured to use the Elasticsearch TCP readiness port. This change also improves cluster upgrade stability by fixing a bug in the upgrade process.

Connect ECK managed applications to a Serverless Project

The ECK operator can now detect when a remote service is deployed in Elastic Cloud Serverless. This allows the use of the [{p}-connect-to-unmanaged-resources] feature to connect a ECK managed resource to your serverless project.
