Elastic Cloud on Kubernetes 2.4.0

• Release highlights
• Quickstart guide

Breaking changes

• Configure Elastic Agent host path volume to point to correct path #5890 (issue: #4428)

  Fleet-managed Elastic Agents now default to use a hostPath volume for storing their state. This will prevent more than one Pod from the same Elastic Agent Deployment to be deployed on the same Kubernetes node. For cases where this is desired, the volume type can be changed to an emptyDir volume. Check the docs to learn more.
