Netopeer2-server listening on ipv6

[Vineet0197]

My Kubernetes cluster supports only IPv6 to establish communication between two pods. And this netopeer2-server is running as a process inside one of my application pod. please help me how I can achieve to make this netopeer2-server listening on ipv6 ?

FYI, supervisord.conf includes following for netopeer2-server :

[inet_http_server]
port = 0.0.0.0:9001

[program:netopeer2-server]
command=/usr/local/bin/netopeer2-server -d
autorestart=true
startretries=10
redirect_stderr=true
priority=4

Output for the processes running in my application :

I want this netopeer2-server to use tcp6 for listening on ipv6. This is CRITICAL feature I want to implement in my official project.

Just edit the configuration of the server. You can use sysrepocfg -Evim -d running -m ietf-netconf-server, there you can change the local-address value to ::, for example. To make sure the change is kept even after a reboot, do the same change using -d startup parameter as well.

Instead of this manual configuration change, can you help me to do this configuration at the startup of this netopeer2-server process inside my application using supervisord.conf ?

[Vineet0197]

Thanks @michalvasko for the support. I able to enable netopeer2-server listening on ipv6 using the above command at the startup itself.

[michalvasko]

That is fine because pretty much the same way even the default configuration is set up.
