2.2.0 release highlights

New and notable changes in version 2.2.0 of Elastic Cloud on Kubernetes. Check Elastic Cloud on Kubernetes version 2.2.0 for the full list of changes.

ECK offers a convenient way to associate Elastic Stack resources together, but it requires them to be all managed by ECK in the same Kubernetes cluster. ECK 2.2.0 makes it possible to associate with external Elastic resources not managed by ECK using a custom Secret containing the connection information to this external resource.

For example, you can now use an Elastic Cloud Elasticsearch cluster to monitor Elasticsearch clusters and Kibana instances managed by ECK by combining Stack Monitoring and this new feature.

spec:
  monitoring:
    metrics:
      elasticsearchRefs:
      - secretName: external-cloud-es-monitoring-ref
---
apiVersion: v1
kind: Secret
metadata:
  name: external-cloud-es-monitoring-ref
stringData:
  url: https://monitoring.es.abc-0.xyz.com:1234
  username: monitoring-user
  password: REDACTED

To avoid some confusion, the Enterprise Resource Units (ERU) are reported in raw bytes and in Gibibyte (GiB) instead of Gigabyte (GB). The ERU calculation has been aligned so that 1 ERU equals to 64 GiB.

ECK supports Service Accounts to secure the connection between Kibana or Fleet Server and Elasticsearch.

The Stack Monitoring feature is fully operational to be used for Elasticsearch self-monitoring.
