====
*Details* +
The `elastic-agent-autodiscover` Kubernetes library by default comes with `add_resource_metadata.deployment=false` and `add_resource_metadata.cronjob=false`.
*Impact* +
Pods that will be created from deployments or cronjobs will not have the extra metadata field for `kubernetes.deployment` or `kubernetes.cronjob`, respectively. This change was made to avoid the memory impact of keeping the feature enabled in big Kubernetes clusters.
