IPv6 in Docker containers

[duckduck]

Hi all,

I'm trying to spin up some Docker containers in my lab, it works great but I can't figure out how to enable IPv6. My EVE-NG host has IPv6 enabled.

If I create a Docker container from the CLI the container has IPv6 enabled. If I create a Docker container (from the same Docker image) through the EVE-NG web gui, IPv6 is disabled. If I try to enable it with sysctl I get an error message about it being a read-only file system.

Is there a startup script that disables it? Any setting I need to change? Any other ideas?
