How this is done in practice varies from hosting provider to hosting provider, but in general you should have access to a DNS or subdomain feature for your domain, where you can add a hostname for your newly configured SOLECTRUS server. + +Using these tools, you need to choose a name for your subdomain and add the IP address of your SOLECTRUS server to a so-called "A" record. + +For example, let's say you own `mydomain.de`, your server has IP address 1.2.3.4 and your chosen SOLECTURS subdomain is `solectrus.mydomain.de`. You will need to add an "A" record to your DNS that maps `solectrus.mydomain.de` to the address 1.2.3.4 + +To verify if this step was successful, try accessing `http://solectrus.mydomain.de` from your browser or use tools like `dig` or `ping` to check if the name resolution works. + +### b) change the firewall configuration for your server + +It is generally a good practice to protect your server using a firewall, and all hosting providers offer a way to do so. + +Go to your server's configuration console. If you do not already have a firewall configured, add one! This firewall must allow incoming TCP traffic on ports 22 (for ssh), 80 (for http), 443 (for https) and 8086 (for influxdb). + +### c) add traefik and Let's Encrypt to your docker configuration + +Log in to your SOLECTRUS server and go to the solectrus directory (`cd solectrus`). Now, perform these commands: + +``` +mkdir letsencrypt +touch letsencrypt/acme.json +chmod 600 letsencrypt/acme.json +``` + +Open your `docker-compose.yml` file in an editor and add this snippet: + +``` +traefik: + image: "traefik:v2.11" + command: + - "--providers.docker=true" + - "--providers.docker.exposedbydefault=false" + - "--entrypoints.web.address=:80" + - "--entrypoints.websecure.address=:443" + - "--entrypoints.influxdb.address=:8086" + - "--certificatesresolvers.myresolver.acme.tlschallenge=true" + - "--certificatesresolvers.myresolver.acme.email=email@mydomain.de" + - "--certificatesresolvers.myresolver.acme.storage=/letsencrypt/acme.json" + ports: + - "80:80" + - "443:443" + - "8086:8086" + volumes: + - "./letsencrypt:/letsencrypt" + - "/var/run/docker.sock:/var/run/docker.sock:ro" + restart: always +``` + +to the `services` section. Replace `email@mydomain.de` with an email address that you own. This adds the `traefik` proxy which will listen on ports 80 (for http), 443 (for https) and 8086 (for the influxdb collector). + +### d) reconfigure the app + +Now, add this snippet to the `app` section of your docker-compose: + +``` +labels: + - "traefik.enable=true" + - "traefik.http.routers.app-solectrus.rule=Host(`solectrus.mydomain.de`)" + - "traefik.http.routers.app-solectrus.entrypoints=websecure" + - "traefik.http.routers.app-solectrus.tls.certresolver=myresolver" + - "traefik.http.middlewares.redirect-to-https.redirectscheme.scheme=https" + - "traefik.http.routers.redirs.rule=hostregexp(`{host:.+}`)" + - "traefik.http.routers.redirs.entrypoints=web" + - "traefik.http.routers.redirs.middlewares=redirect-to-https" +``` + +(replacing `solectrus.mydomain.de` with your chosen subdomain name).

Also, all requests to `http://solectrus.mydomain.de` will be redirected to `https://solectrus.mydomain.de`. + +Also in the `app` section, remove these two lines: + +``` +ports: + - 80:3000 +``` + +### e) reconfigure influxdb + +Then, add this snippet to the `influxdb` section: + +``` +labels: + - "traefik.enable=true" + - "traefik.http.routers.influxdb-solectrus.rule=Host(`solectrus.mydomain.de`)" + - "traefik.http.routers.influxdb-solectrus.entrypoints=influxdb" + - "traefik.http.routers.influxdb-solectrus.tls.certresolver=myresolver" + - "traefik.http.routers.influxdb-solectrus.tls=true" +``` + +Again, replacing `solectrus.mydomain.de` with your chosen subdomain.
