docker-engine 20.10.6 broke container port forwarding for hosts without IPv6
support:
docker: Error response from daemon: driver failed programming external
connectivity on endpoint naughty_moore
(038e9ed4b5ea77e1c52462d6d04ad001fbad9beb185a6511aadc217c8a271608): Error
starting userland proxy: listen tcp6 [::]:80: socket: address family not
supported by protocol.
Add a libnetwork patch from an upstream pull request to fix this, after
adjusting the patch to apply to docker-engine (which has libnetwork vendored
under vendor/github.com/docker/libnetwork):
