Create a nginx reverse proxy by issuing the following command:> docker

docker run -d \
--net host \
--restart=always \
-p 80:80 \
--name proxy \
-v

...

 $PWD/conf:/etc/nginx/

...

sites-enabled \
-v $PWD/letsencrypt:/etc/letsencrypt \
-v $PWD/conf.d:/etc/nginx/

...

conf.d \
lerenn/nginx-reverse-proxy

This will create a reverse proxy running on the host network. We specify a SITES_CONFIG_DIR where we will add our site config files (see below).We also specify a folder for our certificates that we will reference for our SSL enabled sites. 

Define our Nginx Configuration Files

In the config folder conf folder(mapped to sites-enabled) we defined in our docker command we will add a configuration like the following:

server {
        listen       80;
        server_name  wiki wiki.jmehan.com;
        location / {
            proxy_pass         http://192.168.1.60:8090/;
        }
}

Adding SSL Support (not certbot)

If we want to terminate an SSL connection at our proxy, we can generate an SSL cert and configure it in nginx.

...

server {
        server_name  kibana kibana.jmehan.com;
        location / {
            proxy_pass         http://192.168.1.60:5601/;
            auth_basic "Administrator's Area";
            auth_basic_user_file /etc/nginx/conf.d/htpasswd;
        }
}

Customized Dockerfile

The following Dockerfile adds certbot and apache2-utils to our nginx-reverse-proxy image.

FROM lerenn/nginx-reverse-proxy

RUN apt-get update
RUN apt-get install -y wget
RUN apt-get install -y apache2-utils
RUN wget https://dl.eff.org/certbot-auto
RUN chmod +x certbot-auto
RUN ./certbot-auto -n --install-only
