Hello Team

I installed Kibana in docker, while the first set up it showed

```auto
[2022-11-07T09:58:18.929+00:00][INFO][node] Kibana process configured with roles: [background_tasks, ui]
[2022-11-07T09:58:40.484+00:00][INFO][plugins-service] Plugin "cloudExperiments" is disabled.

 FATAL Error: Port 5601 is already in use. Another instance of Kibana may be running!

```

And I tried `ps aux | grep kibana`, `lsof -i:5601`, `ss -lntup | grep 5601` I can only know 5601 is listening but dont know the PID.

The content of my `kibana.yml` is:

```auto
# **THIS IS AN AUTO-GENERATED FILE**
#

# Default Kibana configuration for docker target
server.host: "0.0.0.0"
server.shutdownTimeout: "5s"
elasticsearch.hosts: ["http://elasticsearch:9200"]
monitoring.ui.container.elasticsearch.enabled: true

```

Any help please.

Are you sure there are no other docker containers using the host port? Does `docker ps` show any other running containers?
