Here is Docker-Compose configuration for production purpose. Everything is automated from creating containers to setting up the database. A simple docker-compose up does everything and gives a running website : front-end, back-end and database. However, you still have to add the back-end URL on the front-end interface as we don't see a way to automate it. We include the Dockerfiles so you can build the images yourself. The docker-compose.yml is here for demonstration purpose. You may want to use Docker with Kubernetes for example for production.

1. Get and install Docker https://www.docker.com/get-docker on your machine
2. Download pia-docker.zip and unzip it.

1. Fill the environment variables in docker-compose.yml
2. Open a shell and switch to the pia-docker directory
3. Run the containers by typing docker-compose up into the shell
4. Access the website with localhost:8080 or yourdomain.net:8080

The installation under Windows 10 is described in the Wiki: https://github.com/kosmas58/pia-docker/wiki/Installation-under-Windows-10

• Press "Start" in the PIA frontend or client
• Then in frontend or client set this URL to enable the server mode.
• Fill the field in "Tools" > "Settings"

To setup PIA with SSL/TLS encryption (i.e. access it with https:// later), you first need to obtain a valid certificate and key from your certificate authority of choice. As an example, we will assume a LetsEncrypt certificate obtained by certbot is available at the host machine (the machine docker runs on).

1. Mount the directory containing the certificate and private key in cnil-pia-back and cnil-pia-front

For the letsencrypt example this should be a modification in the docker-compose file like:

  volumes:
  - "/etc/letsencrypt:/etc/letsencrypt"

(Yes, the whole /etc/letsencrypt directory is necessary, as certbot links the most recent certificate using soft links. The real certificate and private key reside under archive with changing filenames.)

2. Change the target port of cnil-pia-front to 443 in the docker-compose.yml

In the backend, we need to force ssl for ruby-on-rails (i.e. the puma application server).

3. Uncomment config.force_ssl = true in the environment/production.rb config file.
4. Change the command executed by docker to start the container pointing to SSL certificate and key

You could do this by adding a simple sed command and by chaning the CMD line in the Dockerfile of the backend:

...
# Force SSL in production
RUN sed -i 's/# config.force_ssl = true/config.force_ssl = true/' config/environments/production.rb

COPY entrypoint /entrypoint
RUN chmod +x /entrypoint
ENTRYPOINT ["/entrypoint"]

CMD ["bundle", "exec", "puma", "-b", "ssl://0.0.0.0:3000?key=/etc/letsencrypt/live/www.example.com/privkey.pem&cert=/etc/letsencrypt/live/www.example.com/fullchain.pem"]

5. Modify the nginx configuration of cnil-pia-front to listen to ssl

Instead of listening to port 80, the standard SSL port 443 has to be setup. You can change this in docker/cnil-pia-front/conf/cnil_pia.conf:

server {
    listen 443 ssl;
    server_name _;
    root /var/ww/pia/dist/;

    ssl_certificate /etc/letsencrypt/live/www.example.com/fullchian.pem;
    ssl_certificate_key /etc/letsencrypt/live/www.example.com/privkey.pem;

    location / {
    }
}

This should do the trick, use docker-compose up -d as usual to start HTTPS-enabled pia!
