-==== Known Workarounds
+If you're monitoring Docker containers or Kubernetes pods, you can use autodiscover to automatically change the configuration settings in response to changes in your containers.
+This ensures you don't stop collecting data when your container configuration changes.
+To learn how to do this, see:
 
-*Running Metricbeat <=6.5 with Kibana 6.6+*:: For Kubernetes, you will need to change the "Pod ID" field in the "Configure Source" panel (`xpack.infra.sources.default.fields.pod` in `config/kibana.yml` for Kibana 6.6) to `kubernetes.pod.name`. There is a caveat for this workaround; if you have two pods with the same name, only one will be visible in the UI.
