Update the kernel configuration for cgroup v2
KentaTada opened this issue · 20 comments
Kubernetes 1.25 brings cgroup v2 to GA.
cgroup v2 needs some additional kernel configs.
For example, you need to enable CONFIG_CGROUP_BPF if you want to use the the device controller.
When it comes to Kubernetes, I have never investigated what config is actually needed.
But I just create an issue at first.
CONFIG_CGROUP_BPF - Required for cgroupv2 (for controlling devices)
containerd/containerd#3799 (comment) by @AkihiroSuda
kernel >= 4.15 with CONFIG_CGROUP_DEVICE and CONFIG_CGROUP_BPF is required.

@pacoxu @KentaTada do we still need such a change?
Yes. We need to investigate and prepare for the kernel configuration for cgroupv2.
If I have time, I'll investigate it.
thanks, @KentaTada
