dockerd fails if the docker0 bridge hasn't been created first

# dockerd
[...]
failed to start daemon: Error initializing network controller: Error creating default "bridge" network: failed to check bridge interface esistence: route ip+net: no such network interface
# ifconfig bridge create name docker0
# dockerd
[success]

I tried to reboot the machine and tried to relaunch dockerd and it still didn't work. However once the ifconfig command was executed, dockerd worked and even after a reboot without having to relaunch the ifconfig command first.

If it helps here is what my /etc/pf.conf and /etc/rc.conf look like:

FreeBSD/arm64 isn't supported

Currently only amd64, i386 and arm (32) seem to be explicitly supported by this fork of docker. However I think it would be interesting to be able to use docker on a Raspberry Pi 4 running FreeBSD, for instance.

To make it work, a couple of arch specific files are missing in cli/vendor/golang.org/x/sys/unix, such as cli/vendor/golang.org/x/sys/unix/ztypes_freebsd_arm64.go for instance. Currently trying to build docker on a Raspberry Pi 4 running FreeBSD results in:

ipv6 requests inside a container fail with "UDP connect: No route to host"

# docker run --rm -it kwiat/freebsd:13.0-RELEASE ping -6 google.com
ping: UDP connect: No route to host

64 bytes from ...
[works as intended]

This thread from the freebsd-net mailing-list points to service ip6addrctl start https://www.mail-archive.com/[email protected]/msg64533.html but all i get is:

Symlinks disappear between commands in docker build

Docker infinit loops when the command requested does not exist

Of course bash does not exist on FreeBSD, I tried it out of habit with linux images. However this command despite displaying an error message did not return to the parent prompt and none of my subsequent ^C on ^Z were successful. The only thing that worked was killall -9 docker from another terminal.

zfs failure "cannot unmount" when stopping the container

Steps to reproduce:

host# docker run --rm -it kwiat/freebsd:13.0-RELEASE sh
container# pkg install git
container# ^D

Build instructions?

The only things that I can find that look like a build system in the repo seem to assume that I already have working docker tools. How do I do a bootstrap build on FreeBSD?
