Hey @lslz627, thank you for reaching out. I was able to reproduce your issue by installing Docker Desktop 3.3.3.
After going through each Docker Desktop version one-by-one, I've finally determined that the issue is related to the Linux kernel version. Docker Desktop 3.3.0 - 3.5.2 uses kernel version 5.10.25-linuxkit
which doesn't appear to load the WireGuard kernel module by default (WireGuard is required for docker-mac-net-connect
). Tested using:
$ ip link add dev wg0 type wireguard
RTNETLINK answers: Operation not supported
I wasn't able to manually load it either:
$ modprobe wireguard
modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/5.10.25-linuxkit/modules.dep.bin'
modprobe: FATAL: Module wireguard not found in directory /lib/modules/5.10.25-linuxkit
The issue is fixed in Docker Desktop 3.6.0+ which uses kernel version 5.10.47-linuxkit
:
$ ip link add dev wg0 type wireguard
$ ip a
...
9: wg0: <POINTOPOINT,NOARP> mtu 1420 qdisc noop state DOWN group default qlen 1000
link/none
Is there any reason you are using an older version of Docker Desktop? Upgrading to at least 3.6.0 should solve your problem.
I did a deep dive into linuxkit
commit history to try to determine what exactly changed between 5.10.25
and 5.10.47
, but unfortunately it wasn't clear when this actually happened (first appearance of 5.10.x
was already at 5.10.34
). Perhaps Docker Desktop used a forked version of linuxkit
(you can see they publish their docker/for-desktop-kernel
separately from linuxkit/kernel
), which unfortunately they don't provide the source code for.
Let me know if this helps you move forward or if you have any other questions.
@gregnr Thank you for taking the time to look at my problems,I have upgrade my docker to latest version ( 4.8.2 ) by your remaining and now it's ok
