How to disable ipv6 in a container on GOS.

[tomoyukinomura55031]

Hi

I am running the lxc container on IR829 GOS.
Ipv6 is automatically enabled on eth0 in the container.
I want to disable it.
Is there any way?

I did "[app -> resources -> network -> ipv6_required: false]" on this page, but it didn't work.

I recommend to try adding the following to the Docker Compose:

sysctls:
  - net.ipv6.conf.all.disable_ipv6=1

It used to be the following , but was changed for version3 compose files:

network:
  - enable_ipv6: false
