Thanks for the detailed response. You mentioned "GKE's Docker containers run in privileged mode", do you why this is?

Not sure. Speculating here, but it's possible that it's because they're still working on building out GKE itself.

GKE is basically a wizard that just runs a pre-built image for the master and node VMs, and comes with some support for upgrades. There are very few settings [1] aside from the machine type. So it's pretty rudimentary. You'd think that GKE would come with a flashy dashboard for pods, deployments, user management, autoscaling and so on, but you're actually stuck with kubectl + running the Dashboard app [2] as a pod, which, while nice enough, is not integrated into the Google Cloud Platform web UI at all. Kubernetes runs fine, but GKE itself feels unfinished.

Anyway, a lot of people were asking for privileged mode back in 2015 [3], and it kind of looks like they turned it on by default rather than developing a setting for it.

Interesting. So the master and the VMs are deployed in KVM or Docker containers running inside of KVMs then?
