Windows Tcp Client Server Deployment

This will enable client server test connection tool which can be run in Windows AKS.

1. Create TCP Server Deployment

Create namespace demo

kubectl create namespace demo

kubectl create -f yamls\server-deployment.yaml

2. Create TCP Server Service

kubectl create -f yamls\server-svc.yaml

3. Create TCP Client POD

kubectl run -it tcp-client -n demo --image=princepereira/tcp-client-server --command -- cmd

If the above session is ended, resume using below command:

kubectl attach tcp-client -c tcp-client -i -t -n demo

4. Establish cient server connection

Get the service IP

kubectl get services -n demo

Connect client to server

client -i <Service IP> -p <Internal Port> -c <No: of Connections> -r <Reqs per Conn> -d <Delay in ms for each req per conn>

Eg: client >> client -i 127.0.0.1 -p 4444 -c 10 -r 10 -d 50

Or you can use the domain name also to make the connection

Domain name: <service-name>.<namespace>.svc.cluster.local

Eg: tcp-server.demo.svc.cluster.local
client >> client -i tcp-server.demo.svc.cluster.local -p 4444 -c 10 -r 10 -d 50
