reverse proxy nginx with docker compose

[akhila1518]

You will create a solution that will have

A nginx reverse proxy two backed nginx servers. the nginx reverse proxy will be the one that will be exposed, when access localhost/pageone request will be for container nginx 1, when access localhost/pagetwo, request will be for nginx container 2 nginx1 and nginx 2 both will have a index.html showing the name of each container, container one, container two.

And when access localhost the nginx reverse proxy will balance the connection between container one and container two, when access using browser or curl it will show the container one page index.html or the container two page index.html

Feel free to use gpt to better understand this, but take in mind, you need understand very well the arquitecture.

Also:

• [ ] create a diagrama of the solution using draw io, you need create manually
• [ ] put the code and coumentation in a diferent folder
• [ ] create a very detailed README.md about the solution on the folder, this will be your writen documentation.

This is a basic but at same time high level project that will prepare you to more advancend things related to kubernetes for example.

Hello @akhila1518 , where is the new project for the reverse nginx proxy asked? and the diagram? We need this before proceed to create the pipeline. please, create a folder on the root called nginx_reverse_proxy with the Docker compose, docker file, diagrams, and all the needed files. Provide evidence that solution is running. Here a example but stick on what was instruced please

@akhila1518 I did a test and is not working, tried to validated the nginx.conf but have a error, belo the testing

http {
    upstream backend {
        server nginx1:80;
        server nginx2:80;
    }

    server {
        listen 80;

        location /pageone {
            proxy_pass http://nginx1;
        }

        location /pagetwo {
            proxy_pass http://nginx2;
        }

        location / {

@akhila1518 after fix, please, test with curl and provide evidences, so I can validate locally as well.
