port 3000 unavailable from docker

[aduclert]

Hello

I'm interested in using directly Z-Wave JS UI without home assistant to simply pilot zwave switches programmatically.

I tried the docker command line available on the site, including the port mappings -p 8091:8091 -p 3000:3000 :

• port 8091 is available, I can access to the web interface and do the config.
• I can switch on/switch off a node.
• but port 3000 is not available :

the mapping is there :

pi5|~]docker container port beautiful_elion
3000/tcp -> 0.0.0.0:3000
3000/tcp -> :::3000
8091/tcp -> 0.0.0.0:8091
8091/tcp -> :::8091

but no listening socket on port 3000, only on port 8091 :

pi5|~]docker container exec -it beautiful_elion netstat -utln
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       
tcp        0      0 :::8091                 :::*                    LISTEN

and I cannot join port 3000 on localhost :

pi5|~]telnet localhost 3000
Trying ::1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

I noticed that in the Dockerfile available from the site, there is an EXPOSE 8091, but no EXPOSE 3000.

Is there something I did not understand ?

Thanks

@aduclert EXPOSE is not mandatory, even if missing you should still be able to access that port once you map it to a local port.

Do you have zwave js server enable in your settings?

Hi Daniel

Ha, yes sorry, as this was labeled Home Assistant that I'm not using, I didn't even try that. Indeed, selecting WS Server activates the listening to the port.

Thanks a lot for your answer.
