Configuring Nginx as SSL proxy server for Tangerine

Update

Issue #3147 describes the start-ssl.sh script that automates installation of the SSL certificates as well as the letsencrypt-nginx-proxy-companion and nginx-proxy containers. The first time it runs it may error out - do a docker logs -f letsencrypt-nginx-proxy-companion to see error. If it does, restart the container (docker restart letsencrypt-nginx-proxy-companion).

You may disregard the following notes - the new script supersedes them; however, they may have some useful information.

Initial configuration

First open config.sh and change the port mapping of Tangerine

T_PORT_MAPPING="-p 8080:80"

Rebuild the container by running ./start.sh

Pull nginx docker image and install certbot inside the nginx container

If your container is not called tangerine adjust below. --link is to allow the ngin container to forward to the tangerine one

docker pull nginx
docker run -p 80:80 -p 443:443 --link tangerine:tangerine --restart always --name nginx -d nginx

Go into the nginx container and execute the below commands

docker exec -it nginx bash

apt-get update && apt-get install certbot vim python3-certbot-nginx -y

Open the config file

vi /etc/nginx/conf.d/default.conf

Adjust the server_name to your domain and the size of the client body

server_name My.Domain.com;
client_max_body_size 0;

Replace the location directive with the one below:

location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            proxy_pass_header  Server;
            proxy_set_header   Host $http_host;
            proxy_redirect     off;
            proxy_set_header   X-Real-IP $remote_addr;
            proxy_set_header   X-Scheme $scheme;
            proxy_set_header X-Forwarded-Host $host:$server_port;
            proxy_set_header X-Forwarded-Proto https;
            proxy_pass         http://tangerine;
        }

Save the file and exit vi

Now execute and follow the promtps for cerbot. It will fail but that's ok

certbot --nginx

The above will generate the certificate according to My.Domain.com name given. Select options 1. My.Domain.com

Reload the config by running

nginx -s reload

Exit the nginx container and add some configuration for autmatic updates of certificates Execute crontab –e and add the line below

 0 3 * * * docker exec -it nginx certbot renew --post-hook "service nginx reload"

Optionally save your image to your docker images

docker commit nginx nginx/nginx:configuredNginx

Note that your nginx container is now linked to your tangerine container. Every time you execute start.sh for tangerine you have to start a new nginx continer to udpate the link. TO recreate using the saved image run 'docker run -p 80:80 -p 443:443 --link tangerine:tangerine --restart always --name nginx -d nginx/nginx:configuredNginx'

Point your DNS to the actual server
