DNS Resolution Fails

[aldobarr]

Description

Starting docker desktop destroys DNS resolution in WSL 2 instances.

Please see this issue for extra details:
microsoft/WSL#11445

Reproduce

1. Open WSL 2 instance integrated with docker desktop
2. Open docker desktop

Expected behavior

$ ping google.com

should result in

PING google.com (142.250.189.142) 56(84) bytes of data.
64 bytes from mia09s26-in-f14.1e100.net (142.250.189.142): icmp_seq=1 ttl=116 time=5.39 ms

or similar

Instead I get

ping: google.com: Temporary failure in name resolution

docker version

4.29.0

docker info

unnecessary

Additional Info

As I mentioned in the WSL issue I linked,

I downgraded docker desktop to 4.24.0. Afterwards I was able to edit "bip" from docker engine in the app itself without error that 4.28.0 and later versions give. After setting bip, dns in WSL is working again.

Hello @aldobarr had the same issue. I downgraded Docker Desktop to version 4.27.2 https://docs.docker.com/desktop/release-notes/#4280 to work normally.

& '.\Docker Desktop Installer.old.exe' install --disable-version-check

I tried all the versions today between 4.27.2 and 4.24.2. All have the "bip" must be an ipv4 address error after version 4.25.2. Although 4.25.0 - 4.25.2 do not have this error, the fix does not work on these version. From 4.25.0 onwards docker is completely unusable. 4.24.2 is the latest version I can use that works.
