Hosting Plausible Analytics On A Raspberry Pi 4 with SSL

April 19, 2023    Self-hosted RPi Analytics ☕️ buy me a coffee



Plausible is a great alternative to Google Analytics if you want to havbe the option of analytics but actually respect your users privacy. Along with that bold statement, Plausible actually offers a whole range of benefits:

  • Guaranteed to be in the region you expect it to be
    • EU if not self-hosted, else whereever you desire
    • This is especially true for GDPR and other data collection laws
  • Substantially lower script size for faster loading times
  • No cookie tracking or other invasive methods used

Now, the fine folks at Plausible have already created amazing documentation on how to get up and running with plausible/hosting. However, this uses an outdated docker image that does not support the Raspberry Pi 4. Therefore, we have this wee guide!

Step 1: The Config Repo

As mentioned above, the original repo does not truly support the RPi4, and until PR#70 is merged, you can get a working configuration at my fork: iwishiwasaneagle/plausible-hosting-rpi

Step 2: Run it!

This is simple, cd into the directory, follow the steps here to generate a random secret key, and run docker compose up -d

Is that it? Well, technically yes but also no. First of all, head to http://localhost:8000 and this should outline some issues. Plausible is running perfectly but on localhost and without SSL. This means you won’t be able to integrate Plausible into your website in any meaningful manner, and not securely.

Step 3. The Rest Of The Owl

So, we now have a working instance accessible at http://localhost:8000. You either need a static IP and a DNS A or AAAA listing pointing at it, ooooor a dynamicDNS service like DuckDNS. There are millions of resources out there on how to set this up so I won’t bother.

Make sure you have your port 80 (HTTP) and 443 (HTTPS) forwarded (again, millions of tutorials, beyond the scope of this tutorial, blah blah blah) to your Raspberry Pi’s local IP address. This is critical to get your SSL certificate.

We will now edit our docker-compose.yml to look like:

version: "3.3"
services:
  mail:
    build: docker-smtp/latest
    restart: always
    networks:
      - internal

  plausible_db:
    # supported versions are 12, 13, and 14
    image: postgres:14-alpine
    restart: always
    networks:
      - internal
    volumes:
      - db-data:/var/lib/postgresql/data
    environment:
      - POSTGRES_PASSWORD=postgres

  plausible_events_db:
    image: clickhouse/clickhouse-server:22.6-alpine
    restart: always
    networks:
      - internal
    volumes:
      - event-data:/var/lib/clickhouse
      - ./clickhouse/clickhouse-config.xml:/etc/clickhouse-server/config.d/logging.xml:ro
      - ./clickhouse/clickhouse-user-config.xml:/etc/clickhouse-server/users.d/logging.xml:ro
    ulimits:
      nofile:
        soft: 262144
        hard: 262144

  plausible:
    image: plausible/analytics:v1.5
    restart: always
    command: sh -c "sleep 10 && /entrypoint.sh db createdb && /entrypoint.sh db migrate && /entrypoint.sh run"
    networks:
      - expose
      - internal
    depends_on:
      - plausible_db
      - plausible_events_db
      - mail
    env_file:
      - plausible-conf.env
  
  nginx:
    image: nginx
    restart: always
    volumes:
      - ./nginx/:/etc/nginx/conf.d
      - ./data/certbot/conf:/etc/letsencrypt
      - ./data/certbot/www:/var/www/certbot
      - ./nginx/error.log:/var/log/nginx/error.log
    networks:
      - expose
    ports:
      - 80:80
      - 443:443
    environment:
     - NGINX_HOST=127.0.0.1
     - NGINX_PORT=80
    command: "/bin/sh -c 'while :; do sleep 6h & wait $${!}; nginx -s reload; done & nginx -g \"daemon off;\"'"

  certbot:
    image: certbot/certbot
    restart: always
    volumes:
      - ./data/certbot/conf:/etc/letsencrypt
      - ./data/certbot/www:/var/www/certbot
    entrypoint: "/bin/sh -c 'trap exit TERM; while :; do certbot renew; sleep 12h & wait $${!}; done;'"

volumes:
  db-data:
    driver: local
  event-data:
    driver: local
  geoip:
    driver: local
  
networks:
  expose:
  internal:

The correct usage of the networks us key, otherwise the nginx container can’t access plausible which then won’t be accessible over the internet. Now mkdir two directories: nginx and data, and create the following file at nginx/plausible.conf:

server {
    listen 80;
    listen [::]:80;

    location /.well-known/acme-challenge/ {
      root /var/www/certbot;
    }
    location / {
        return 301 https://$host$request_uri;
    }
    server_name _;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name yourdomain.com;

    ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;

    location / {
        proxy_pass http://plausible:8000;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

It is now time to get your SSL certificate and to enable HTTPS on your Plausible instance. Download the init-letsencrypt.sh and edit it to include your your domain name. Give it execution permissions via

chmod +x init-letsencrupt.sh

and run it!

Be sure to change BASE_URL within plausible-conf.env to whatever yours is for Plausible to play nicely.

Step 4. Add script.js To Your <head>

<script defer data-domain="yourdomain.com" src="https://yourdomain.com/js/script.js"></script>

If you are self-hsoting, which is probably why you’re reading this, it is important in my opinion that you DO NOT use the script located at https://https://plausible.io/js/script.js. You are not paying for any bandwidth, and therefore shouldn’t be freeloading. Use Cloudflare or another CDN if your private bandwidth is a concern.

Conclusion

Plausible was really simple to set up in workflow and I hope this guide has helped you. There are additional things you can consider doing which I’ll link below. What I really appreciate about Plausible is not invading the privacy of the people visiting my website, whilst still giving me insight as to what is going on.
