You have a running production container (a synced node) and you would want to either edit or bind new ports in this container, as opposed to spinning up a new container.

The following steps should aid you to achieve this.

1.Stop the running Container

 docker stop <container-id> 

2.Open Docker containers directory

 /var/lib/docker/containers/ 

 cd <container-id> 

3.Edit hostconfig.json

Open hostconfig.json with nano or vim
locate and edit PortBindings with the new ports you want to edit, open or delete.

for instance

 "PortBindings":{"18332/tcp":[{"HostIp":"","HostPort":"18332"}],"18334/tcp":[{"HostIp":"","HostPort":"18334"}]} 

4.Restart Docker

 systemctl restart docker 

5.Start container

 docker start <container-id>
