Failed to deploy colud-game docker to server

[Imantsg]

I had no problems to run docker image localy but when I am trying to deploy colud-game docker image to server. I have erros.

I changed yaml config:

server-> address changed to :9100 because 8000 port is not usable on my server
worker->network->publicAddress changed to 192.168.8.115 which is my local server ip address

When I run docker image I can connect to http://192.168.8.115:9100 but it fails to show my roms.

And in log I have this error:

2021-12-12T14:10:19.794118001Z I1212 14:10:19.787932      10 server.go:75] Starting http server on localhost:9000

Since you are changed the coordinator address, you should specify that address in the worker config:

worker:
  network:
    # a coordinator address to connect to
    coordinatorAddress: localhost:9000

[Imantsg]

I created new virtual machine and update configuration as you sugested

Now I got this error in server side:

And no roms are shown in list

[sergystepanov]

Try to set the iceIpMap config param to your internal 192.x address or if you want to access it externally, to your public IP (internal won't be working in that case).

[Imantsg]

Is there any example how that map should look like.
I put iceIpMap: 192.168.88.99 (my cloud-game host ip) there and it did nothing

[sergystepanov]

Yes, that should be like that. Strange.
Could you join the discord channel (the link on the main page) where it'll be easier to solve?

[Imantsg]

For those who have same problem as me docker-composer rewrote some of my configuration.
When I set CLOUD_GAME_WEBRTC_ICEIPMAP in docker-compose.yml file to my hot ip address all started to work
