Docker + Browser ?

[accforgithubtest]

Hello there, came across this project and excited to try it out as this looks like a neat project.

I noticed there is a docker compose file - does this mean the game can be played over a browser ?
I used the compose file provided, however when trying to connect via browser, I see a error

Error: Host is not reachable {"protocol":"http:","host":"chess","port":53531}

Is there any additional configurations are required to get to play via browser ?
