Can not bind to interface inside Docker container

[0per8or]

Hello,

I am running Node-RED inside a Docker container with multiple interfaces:

~ $ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 184: eth1@if185: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP link/ether 02:42:ac:10:00:0d brd ff:ff:ff:ff:ff:ff inet 172.16.0.13/16 brd 172.16.255.255 scope global eth1 valid_lft forever preferred_lft forever 186: eth0@if2: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP link/ether 02:42:c0:a8:0b:80 brd ff:ff:ff:ff:ff:ff inet 192.168.11.128/24 brd 192.168.11.255 scope global eth0 valid_lft forever preferred_lft forever

To use Multicast I need to bind KNX Ultimate a specific interface. When I open the Gateway configuration I can chose between 'Auto' and 'Manually enter interface's name'. But unfortunately there is no text field to enter the name.

At the same time there is a exception in the log:

Hi The is unable to list the docker’s eth interfaces. Usually, the interfaces listing returns a list everytime. I’m taking a look and let you know…

node-red-contrib-knx-ultimate-2.4.5-beta.2 is out in minutes, with the fix. Thank you for reporting that.
