+There is nothing special about running Solara in Docker. The only things you probably need to change is the interface the server binds to.
+Solara by default binds to localhost, so that it is not accessible from the outside world. Apart from that localhost (or `::1` in case of IPv6)
+might not be available, you probably want the outside world to see your Solara app. For that, you can use `--host=0.0.0.0` or `--host=::` option to bind to all interfaces.
+
+Your Dockerfile could look like:
+
+```Dockerfile
+FROM ....
+
+...
+CMD ["solara", "run", "sol.py", "--host=0.0.0.0"]
+
+```
