Embedded Jetty Webserver on a fixed Port

I’m running metadata on a MAC.
Every time i start it i can notice on the logs
“metabase.server Launching Embedded Jetty Webserver with config: {:port 13972}”
The port used is changing on every restart. Any way to set this to a fixed port?

Hi @epenedos
I don’t know if the Mac App picks up the environment variable, but you can try setting that and then launching the Mac App again:


I would recommend that you use the JAR instead of the Mac App.
