02/14/2023, 3:02 PMMorning - Rancher Desktop installed using containerd on OS X Ventura. Seem to be having a problem getting to web resources within pods. nslookup from within a pod works perfectly fine, however wget return bad address. Mac currently has firewall disabled. Any ideas?
If I run:
kubectl run -it --rm --restart=Never busybox --image=busybox:1.28 -- wget https://dl-cdn.alpinelinux.org/alpine/v3.17/main/aarch64/APKINDEX.tar.gz
It downloads successfully. However any other pods that are running, it fails with bad address.

02/14/2023, 7:09 PMHmm, there shouldn't be any difference; presumably you've already tried comparing
/etc/resolv.confs
some-book-73639
02/14/2023, 8:22 PMEverything seems fine - hostnames are resolving when using nslookup, so that should rule out the resolv.conf file. No non-default anything that I can see.

02/14/2023, 8:29 PMRight, that was why I mentioned having multiple nameservers in
resolv.confs
some-book-73639
02/14/2023, 8:47 PMNope. It was using the kube-dns server, but for giggles, I added 8.8.8.8 before it just to see. hostnames were always resolving though. Very odd.

02/14/2023, 10:21 PMMaybe something is being silly and trying to use IPv6?
Not that I have particular reasons for thinking that would lead to the described behaviour; this is more just generically blaming IPv6 when I start running out of ideas…

02/23/2023, 3:45 PMI’ve have the same issue with my Mac M1 with wifi only. Lots of weird networking stuff on local cluster and one I built in Parallels. If I had ethernet I’d try that and see if it was any better. The Mac wifi causes me some issues when my networking gets crazy like with k8s and vms.
