This functionality is not supported from the latest release.

Define a TCP liveness probe

apiVersion: v1
kind: Pod
metadata:
  name: goproxy
  labels:
    app: goproxy
spec:
  containers:
  - name: goproxy
    image: k8s.gcr.io/goproxy:0.1
    ports:
    - containerPort: 8080
    readinessProbe:
      tcpSocket:
        port: 8080
      initialDelaySeconds: 5
      periodSeconds: 10
    livenessProbe:
      tcpSocket:
        port: 8080
      initialDelaySeconds: 15
      periodSeconds: 20

Use Named port

ports:
- name: liveness-port
  containerPort: 8080
  hostPort: 8080

livenessProbe:
  httpGet:
    path: /healthz
    port: liveness-port

TcpListiner

using System;  
using System.Net.Sockets;  
using System.Text;  
  
public class TcpTimeServer {  
  
    private const int portNum = 13;  
  
    public static int Main(String[] args) {  
        bool done = false;  
  
        TcpListener listener = new TcpListener(portNum);  
  
        listener.Start();  
  
        while (!done) {  
            Console.Write("Waiting for connection...");  
            TcpClient client = listener.AcceptTcpClient();  
  
            Console.WriteLine("Connection accepted.");  
            NetworkStream ns = client.GetStream();  
  
            byte[] byteTime = Encoding.ASCII.GetBytes(DateTime.Now.ToString());  
  
            try {  
                ns.Write(byteTime, 0, byteTime.Length);  
                ns.Close();  
                client.Close();  
            } catch (Exception e) {  
                Console.WriteLine(e.ToString());  
            }  
        }  
  
        listener.Stop();  
  
        return 0;  
    }  
  
}
