   * Container 8000 reaching container 8001 internally on port 80, without going through your host ports.
+====== Useful cleanup / debug ======
+  * Some handy commands:
+<code bash>
+docker ps                           # see running
+docker network inspect test-radiusdesk  # see which containers + their IPs
+docker logs nginx-8000
+docker stop nginx-8000 nginx-8001 && docker rm nginx-8000 nginx-8001
+docker network rm test-radiusdesk
+</code>
+====== Same thing with docker-compose (cleaner) ======
+  * Create docker-compose.yml:
+<code yaml>
+services:
+  nginx-8000:
+    image: nginx
+    ports:
+      - "8000:80"
+    networks:
+      - test-radiusdesk
+  nginx-8001:
+    image: nginx
+    ports:
+      - "8001:80"
+    networks:
+      - test-radiusdesk
+networks:
+  test-radiusdesk:
+    driver: bridge
+</code>
+  * We can then bring it up with:
+<code bash>
+docker compose up -d
+docker compose down
