 Database logging is disabled by default. You can enable it in ```config.json``` by setting ```logToDatabase``` to true.
 This requires sqlite3 drivers to be installed.

+## Docker
+Minetrack can be built and run with Docker from this repository in several ways:
+
+### Build and deploy directly with Docker:
+```
+# build image with name minetrack and tag latest
+docker build . --tag minetrack:latest
+# start container, delete on exit
+# publish container port 8080 on host port 80
+docker run --rm --publish 80:8080 minetrack:latest
+```
+The published port can be changed by modifying the parameter argument, e.g.:  
+Publish to host port 8080: `--publish 8080:8080`  
+Publish to localhost (thus prohibiting external access): `--publish 127.0.0.1:8080:8080`
+
+### Build and deploy with docker-compose:
+```
+# build and start service
+docker-compose up --build
+# stop service and remove artifacts
+docker-compose down
+```
+
+## Nginx reverse proxy
+The following configuration enables Nginx to act as reverse proxy for a Minetrack instance that is available at port 8080 on localhost:
+```
+server {
+    server_name minetrack.example.net;
+    listen 80;
+    location / {
+        proxy_pass http://localhost:8080;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+    }
+}
+```
