 ## Service node front end
 
 We provide a simple GUI to control ```dkg service node``` in a [separate project](https://github.com/maxirmx/dkg-frontend). 
 
+## Starting servoce node with front-end in a docker container
+```
+version: '3.4'
+
+services:
+  dkgservicenode:
+    container_name: dkg_service_node
+    image: ghcr.io/maxirmx/dkg-service-node:latest
+    environment:
+      - ASPNETCORE_ENVIRONMENT=Production
+      - ASPNETCORE_HTTP_PORTS=8080
+      - ASPNETCORE_HTTPS_PORTS=8081
+      - ASPNETCORE_Kestrel__Certificates__Default__Path=/etc/dkg/s.pfx
+      - ASPNETCORE_Kestrel__Certificates__Default__Password=password
+    ports:
+      - "8080:8080"
+      - "8081:8081"

+      - POSTGRES_PASSWORD=postgres
+      - POSTGRES_DB=dkgservice
+    volumes:

+      - NGINX_SSL_CERTIFICATE_PATH=/etc/nginx/certificate/s.crt

+    volumes:
+# Certificate and key for Nginx are expected at
+# /etc/nginx/certificate/s.crt
+# /etc/nginx/certificate/s.key
+      - /etc/nginx/certificate:/etc/nginx/certificate
+
+volumes:
+  pgdata: {}
+
+```
+
+Note that service node setup requires two SSL certificates
+
+For Nginx (front end application)
+Certificate public and private keys are expected in fixed locations in front-end container - ```/etc/nginx/certificate/s.crt``` and ```/etc/nginx/certificate/s.key```
+
+For Kestrel (service node application)
+PKCS#12 (.pfx) file at configurable location defined by ```ASPNETCORE_Kestrel__Certificates__Default__Path``` environment variable
+Password for PKCS#12 file set at ```ASPNETCORE_Kestrel__Certificates__Default__Password``` environment variable
