+# Docker image
+
+Maven produces a single docker image containing the policy GUIs. These are exposed on
+the same port (8080) using different URLs:
+- Apex Policy Editor: http://localhost:8080/apex-editor
+- PDP Monitoring UI: http://localhost:8080/pdp-monitoring
+- CLAMP Designer UI: http://localhost:8080/clamp
+
+## Building
+You can use the following command to build the policy-gui docker image:
+```
+mvn clean install -P docker
+```
+
+## Deployment
+Currently, the policy-gui docker image can be deployed with minimal configuration. As
+the clamp backend is required to use the clamp GUI, you can use the CLAMP_REST_URL
+environment variable to set its location.
+
+By default, CLAMP_REST_URL is set to an invalid address (0.0.0.0), meaning the CLAMP GUI
+will not work without specifying CLAMP_REST_URL.
+
+If running clamp as part of a docker network, where `policy-clamp-backend` is the CLAMP
+backend, then CLAMP_REST_URL should be set to `https://policy-clamp-backend:8443`.
+
+If running clamp backend on localhost port 8443, the policy-gui docker image would be
+started like this:
+```
+docker run -p 8080:8080 \
+    --add-host host.docker.internal:host-gateway \
+    --env CLAMP_REST_URL=https://host.docker.internal:8443 \
+    onap/policy-gui
+```
