 +**Important Notice:**

 +This is an example for a Reverse Proxy. I will be using Traefik to [[:computer_science:docker:traefik_docker_https_ssl_for_containers|Implementing HTTPS / SSL with Traefik on Docker Containers]] down the line. So use this guide if you want to keep to nginx, else I would recommend going with Traefik.

 +===== Pratical Example =====
 +
 +==== Making the Reverse Proxy ====
 +
 +Let's go ahead and create our folder and create our 2 required files, the docker-compose.yml and the nginx.conf. Navigate to your desired folder and run:
 +
 +<code bash>
 +mkdir nging-reverseproxy
 +touch docker-compose.yml
 +touch nginx.conf
 +
 +
 +</code>
 +
 +Using your favourite method, deploy your **docker-compose.yml **setup. I will be using the good old 'nano'.
 +
 +My configuration would be as follows:
 +
 +<code bash>
 +version: '3'
 +volumes:
 +    dokuwiki_data:
 +        external: true
 +    dokuwiki_conf:
 +        external: true
 +    dokuwiki_lib-plugins:
 +        external: true
 +    dokuwiki_lib-tpl:
 +        external: true
 +    dokuwiki_logs:
 +        external: true
 +
 +services:
 +    nginx:
 +        image: nginx:latest
 +        container_name: nginx_reverseproxy
 +        volumes:
 +          - ./nginx.conf:/etc/nginx/nginx.conf
 +          - ./nginx/error.log:/etc/nginx/error_log.log
 +          - ./nginx/cache/:/etc/nginx/cache
 +          - /etc/letsencrypt/:/etc/letsencrypt/
 +        ports:
 +          - 80:80
 +          - 443:443
 +
 +    dokuwiki:
 +        image: 'mprasil/dokuwiki'
 +        container_name: 'dokuwiki_zebra'
 +        expose:
 +            - '80'
 +        volumes:
 +            - dokuwiki_data:/dokuwiki/data
 +            - dokuwiki_conf:/dokuwiki/conf
 +            - dokuwiki_lib-plugins:/dokuwiki/lib/plugins
 +            - dokuwiki_lib-tpl:/dokuwiki/lib/tpl
 +            - dokuwiki_logs:/var/log
 +
 +
 +</code>
 +
 +And now we edit the **nginx.conf **to point back to our DokuWiki. Note that I will already configure a sub-domain and a main domain, which at the moment would both point to the same container, but once we make [[:computer_science:docker:docker_wordpress_homepage_portable|Wordpress Homepage ToGo with Docker]] we can change just the service name and everything should work properly.
 +
 +<code bash>
 +events {
 +
 +}
 +
 +http {
 +  #error_log /etc/nginx/error_log.log warn;
 +  client_max_body_size 20m;
 +
 +  proxy_cache_path /etc/nginx/cache keys_zone=one:500m max_size=1000m;
 +
 +  server {
 +    server_name wiki.carlossousa.tech;
 +
 +    location / {
 +      include /etc/nginx/includes/proxy.conf;
 +      proxy_pass http://dokuwiki:80/;
 +    }
 +  }
 +
 +  server {
 +    server_name carlossousa.tech;
 +
 +    location / {
 +      include /etc/nginx/includes/proxy.conf;
 +      proxy_pass http://dokuwiki:80/;
 +    }
 +  }
 +}
 +
 +
 +</code>
 +
 +And finally we will once again create a **backup_to_tar.sh **so we can backup our nginx Reverse Proxy setup:
 +
 +<code bash>
 +#!/bin/bash
 +SOURCE_PATH="/home/docker-user/nginx-reverseproxy"
 +BACKUP_PATH="/home/docker-user/backups"
 +BACKUP_NAME="nginx-reverseproxy"
 +tar cvf "$BACKUP_PATH"/"$BACKUP_NAME"-$(date +"%Y-%m-%d-%H-%M").tar -C "$SOURCE_PATH" .
