Hi Vikram, I have run two containers on the different web server, Here I have used nginx alpine image only and running it on two containers on the same host machine.

docker run -d -p 8080:80 --name=nginxone nginx:alpine

localhost:8080

and change the port to 8081 to up another container of nginx.

docker run -d -p 8081:80 --name=nginxtwo nginx:alpine

localhost:8081

apart from that, you can create your own network and communication between these two.

Thanks Shivam to share your knowledge. What I understood from your answer is that we can run multiple web server docker containers on the same host machine but   for each web server docker container, a different port need to be assigned. In your example. One web server would be accessed by using the URL format <host machine ip addrees>:8080 and while the other web server would be accessed by using the URL format <host name ip address>:8081. But I want to access both the web server without specifying port number explicitly. Is it possible ?
