Windows 10 environment

yup proxy issue. try https://docs.rancherdesktop.io/how-to-guides/running-air-gapped/ or you can try the new 1.8 with gvisor enabled and use WSLENV to inject your proxy into env. depending on your VPN you may not need gvisor, but something you can try.
a
Ok, thanks. `WSLENV`iis set and available. The error message is still the same, although the 
k3s-versions.json
file is present and populated in 
%APPDATALOCAL%\rancher-desktop\cache
.

w
yeah that looks like a lot in the electron side vs the WSL side. did you download a tarball for your version? could the proxy require auth or other more finicky settings that RD could be tripping over?
a
It is the 1.8.0 msi installer.
Ok, you mean the source code tarball to debug RD?
w
no the images tarball listed in https://docs.rancherdesktop.io/how-to-guides/running-air-gapped/#the-cache-directory after the versions json
a
Thanks, the air-gapped installation installs k3s and the Kubernetes distribution successfully. When running 
kubectl run rdtest --image=rancher/hello-world
this error occurs:
Copy code
3s          Warning   FailedCreatePodSandBox    pod/rdtest         Failed to create pod sandbox: rpc error: code = Unknown desc = failed pulling image "<http://registry.k8s.io/pause:3.6|registry.k8s.io/pause:3.6>": Error response from daemon: Get "<https://registry.k8s.io/v2/>": dial tcp: lookup <http://registry.k8s.io|registry.k8s.io> on w.x.y.z:53: no such host
I added 
/etc/rancher/k3s/registries.yaml
, ran 
wsl --shutdown
and started rancher desktop again. But same error occurs. It is probably related to the proxy settings of the underlying docker or moby host installation.
w
that is a DNS issue (port 53) so look at how you have configured WSL for DNS, make sure your VPN is forwarding those packets, and check out host resolver https://github.com/rancher-sandbox/rancher-desktop/issues/1899#issuecomment-1109128277
a
Now it is possible to pull images. The host resolver seems to have no effect. I added a nameserver to /etc/resolv.conf. When pulling images, the following error occurs - not sure what to do in this case:
Copy code

w
yeah host resolver is one of those depends on your VPN things. Something seems pretty off in the config as I don’t think 1.8 takes advantage of systemd in WSL1.x and still uses openrc.
a
It is pretty much the RD installation out of the box.

w
yeah but the bootstrap seemed to go off the rails at some point
the install init on first run does a ton of stuff
a
That would be logged to wsl.log most likely.
w
all the tasks are spread over all the logs
you may want to give the gvisor network a try (do a factory reset before) and combine w a WSLENV of your proxy and see if that works out of box

switching to containerd and running rancher/hello-world leads to:

Does not work with either settings. For example networkingTunnel true or false does not make a difference:
