In this repo I collect my docker-compose files.
Enable IPv6 for the docker daemon /etc/docker/daemon.json:
{
"ipv6": true,
"fixed-cidr-v6": "fd00:dead:beef::/48",
"ip6tables": true,
"experimental": true,
}Restart your host to apply the changes.
Create a new external network before starting the ngin-proxy container:
docker network create --ipv6 --subnet fd00:0:0:1::/64 --gateway fd00:0:0:1::1 nginx-proxy
