Docker CE no longer works with WSL 2.0.0 and autoMemoryReclaim=gradual

[felipecrs]

Windows Version

Microsoft Windows [Version 10.0.22631.2338]

WSL Version

2.0.0.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

5.15.123.1-1

Distro Version

Ubuntu 22.04

Other Software

Docker version 24.0.6, installed following https://docs.docker.com/engine/install/ubuntu/.

Repro Steps

1. Be on WSL older than 2.0.0.0
2. Enable systemd through wsl.conf
3. Install docker following https://docs.docker.com/engine/install/ubuntu/
4. Confirm it works by running docker version
5. Update WSL to 2.0.0.0
6. Add autoMemoryReclaim=gradual to .wslconfig's [experimental]
7. docker version times out

Expected Behavior

Docker to work just like before.

Actual Behavior

Docker daemon does not start.

Yes this is a known issue! We are working with the Docker team to get a fix for this.

Thanks for the heads up!

BTW sorry, I made a mistake in the reproduction steps (I said keep the .wslconfig empty while in fact you need autoMemoryReclaim to trigger the issue). I fixed it now.

I believe I have a fix for this issue, we should be pushing a 2.0.1 here in the next couple of days.

@felipecrs when you enable the [experimental] features it disables cgroupv1 nuking docker service which depends on it. See /proc/cmdline and you'll find cgroup_no_v1=all there!

[felipecrs]

Makes sense, but I did some things like:

$ cat > /etc/docker/daemon.json <<EOF
{
  "exec-opts": ["native.cgroupdriver=systemd"]
}
EOF

To make docker use cgroups v2, and it didn't work out well. Maybe I did something wrong though.

[felipecrs]

Please note that I'm not using Docker Desktop.

Saw on #10499, just tested, autoMemoryReclaim=dropcache works with docker as well.

[benhillis]

Fixed with https://github.com/microsoft/WSL/releases/tag/2.0.1.

[felipecrs]

I can confirm it was fixed indeed. Thank you!

Note that although you may think that you've updated WSL with wsl --update --pre-release, for some the update silently fails: #10539
In this case you should install it manually by downloading the MSI.

[felipecrs]

I had noticed the failure when updating as well, and that's why I update through the Microsoft Store. I will double check the version though.

[felipecrs]

Yes, confirmed:

wsl version 2.0.7.0 and .wslconfig with:

[experimental]
autoMemoryReclaim = "gradual"

Docker Desktop cannot start, it hangs forever
