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

Hello Team

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

[2022-11-07T09:58:18.929+00:00][INFO ][node] Kibana process configured with roles: [background_tasks, ui]

 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:

# ** 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?
