Recommended way to run stable + dev/nightly in parallel

[ijc]

For testing of bugs/fixes etc I'd like to be able to run nightly MA alongside the stable instance used day to day on the same machine.

Currently I have two mutually exclusive docker compose stacks and I have to stop stable while I test dev.

The reason for the mutual exclusivity is that they both use the host network stack and want to bind to some of the same ports (notably port 8095 for the UI/API). It's a minor irritant to have to flip between them, I'd prefer to be able to leave stable always running while I mess with the dev/nightly instance.

Is there a recommended/supported way to configure the dev instance to use distinct ports for the required static ports?

If there are particular providers which insist on a specific hardcoded port then I hope I can get away with not running those on the dev instance, but I suppose it depends which ones they are. 🤞 mostly things are using dynamic assignment. I wonder how much of a problem mdns will be.

You can’t run them both at the same time. Just stop one and start the other.

That is for the addon, this is docker.

Pretty sure you can specify the webserver port in settings. Or just run the second instance not in host mode and use manual ip's for setting up players

Thanks @marcelveldt.

I changed the API/web port (8095->8096) and the streaming port (8099->8098) via the UI and that seems to have been enough to allow both instances to run!

Relevant (I think) bits of `settings.json` written by the UI editor

{
  "core": {
    "webserver": {
      "values": {
        "base_url": "http://<REDACTED>:8096",
        "bind_port": 8096
      },
      "domain": "webserver",
      "last_error": null
    },
    "streams": {
      "values": {
        "bind_port": 8098
      },
      "domain": "streams",
      "last_error": null
    }
  },
}

The squeezelite provider complained:

Error loading provider(instance) squeezelite: Multiple ports are not available: SlimProto control port 3483, Telnet CLI port 9090, JSON-RPC CLI port 9000 (will be retried later)

There are options to change all those ports, but for now I've just disabled squeezelite in the dev instance, will revisit if I ever need to test squeezelite on dev.

You can't run 2 slimproto servers on the same host
