I am trying to set up two FTP servers in two different pods of the Kubernetes cluster. I have used internal port 21 and external port 30082 for the FTP server in the first pod and internal port 21 and external port 30083 for the FTP server in the second pod.

I am successfully able to connect with both the FTP server using FTP command but whatever changes I am doing in one FTP server, it is automatically reflecting into the second FTP server which is running in a different pod.

I am a volunteer in Networking, your help is appreciated!
