+# NGINX webserver that serves a simple page containing its hostname, IP address and port as wells as the request URI and the local time of the webserver.
+
+The images are uploaded to Docker Hub -- https://hub.docker.com/r/saifulmr/nginx-hello/.
+
+How to run:
+```
+$ docker run -P -d saifulmr/nginx-hello
+```
+
+Now, assuming we found out the IP address and the port that mapped to port 80 on the container, in a browser we can make a request to the webserver and get the page below: ![hello](hello.png)
+
+A plain text version of the image is available as `saifulmr/nginx-hello:plain-text`. This version returns the same information in the plain text format:
+```
+$ curl <ip>:<port>
+Server address: 172.17.0.2:80
+Server name: hello1
+Date: 19/Sep/2023:16:05:05 +0000
+Host: demo.nginxlab.dev
+URI: /
+Cookie-Session: 
+Remote-Address: 
+X-Forwarded-For: 
+Request ID: 48ba0db334a6ed165e783469c2af868f
+```
+
+The images were created to be used as simple backends for various load balancing demos.
