Been trying to get ipv6 working with docker for days with no luck. Everything I read (for example: ungleich.ch/u/blog/how-to-enable-ipv6-in-docker) seems to suggest it's simple, yet my containers still end up with ipv4 only. Finally found the problem between my keyboard and my chair - editing /etc/docker/daemon.json doesn't help if your docker daemon is running with --config-file=/var/snap/docker/423/config/daemon.json... 👴
