+
+The nginx reverse proxy will listen on ports 80 and 443 for you, and direct traffic to your docker image, which should use a different port.
+
+To do this, you'll need to do a few things. Let's assume you are going to use port 3000
+
+In the `app` section
+
+```
+  docker: { imagePort: 3000 },
+  env: {PORT: 3000}, // This may generate a warning from MUP, you can ignore it.
+```
+
+and in your `Dockerfile`, you will need to add a line
+
+```
+EXPOSE 3000
+```
+
+You may also need to adjust some settings in your docker files to make it listen on port 3000. You should remove anything that attempts to listen on port 443.
