Socket IO not reachable from outside docker

[jovobe]

Expected Behavior

The web view can connect to the socket.io server provided by the bot. No matter if you are running it in docker container or not.

Actual Behavior

When run in docker container the web view can't connect to the socket.io server from the bot. I already added a ports-section (mapped port 4000 to 4000 of host) to the bot container. From within the bot container port 4000 is reachable. From outside the container it says "connection refused".

Your FULL config.json (remove your username, password, gmapkey and any other private info)

{
...
"websocket": {
"start_embedded_server": true,
"server_url": "127.0.0.1:4000"
}
...
}

Steps to Reproduce

docker-compose up from the current master

Can someone help to explain what is the use for this socket io? My web view is working fine without this config.

keep send request to 127.0.0.1 for socker.io
other request send to private Ip (192.168.4.15)

maybe this is why mapping port 4000 won't work.
browser send to 127.0.0.1 (localhost) , not docker server ip ,nor docker container ip
i use docker version too , never make map works.

I already changed the IP in the main.js to the one from the server it changed nothing.

i change two ip and then i finally success.

step 1 / change websocket url from config
"websocket": {
"start_embedded_server": true,
"server_url": "127.0.0.1:4000" <--- change to 0.0.0.0:4000

step 2 / change main.js
socket_io = io.connect('127.0.0.1:4000'); <--- change to your docker server ip
for me , is 192.168.4.15:4000

that's it.

you have to change config, make socket not only listen on 127.0.0.1(localhost)
change to 0.0.0.0 ,seems make server list on all network interface
and i also map port 4000 to outside

Closing as it's a config issue
