BTRFS snapshots world be my first guess. ‘sudo btrfs subvolume list /‘

Did you end up enabling ipv6 as well? Did that help?

If it’s enable then this command should produce a 1 in the output

cat /proc/sys/net/ipv4/ip_forward

Read this section on setting up forwarding on Linux. You’ll want to do this on the host that is running docker and it should carry down into the container itself.
