Does anyone already installed NeuVector in Rancher Desktop? I tried to install using the manifests and helm. For both methods the enforcer pod keeps crashing.
pod/neuvector-enforcer-pod-4qjdl               0/1     CrashLoopBackOff
This is the enforcer pod logs and this is the moment that the pod fails.

Any idea why is this happening?

I think the problem is that
fanotify
support requires Alpine 3.17+ and the Rancher Desktop image is still 3.16 because the 3.17 image on aarch64 doesn't work with Apple's virtualization framework.
Can you open a bug for this on Github? I don't think this will be resolved until the Alpine issue is fixed in upstream, but at least we could test if this is the only issue preventing NeuVector from running.

Hey @fast-garage-66093 thank you so much for your response. Sure I will open a bug in Github.
Not sure if you need the github issue reference, https://github.com/rancher-sandbox/rancher-desktop/issues/4269
