Incomplete description how to properly configure cri-o in kubernetes tutorial

[krisiasty]

Describe the error/improvement to an existing document or image In the manual installation section of kubernetes tutorial documentation the user have to choose one of the runtime engines. The instruction for CRI-O is incomplete and lacks the section describing how to configure kubelet to use systemd as the cgroup driver, which is also necessary for cri-o. Without it, kubelet is not able to spawn any container.

The configuration is exactly the same as for containerd runtime, and should be done BEFORE enabling kubelet and crio service:

# configure kubelet to use systemd as a cgroup driver
sudo mkdir -p /etc/systemd/system/kubelet.service.d/
cat << EOF | sudo tee  /etc/systemd/system/kubelet.service.d/10-cgroup-driver.conf
[Service]
Environment="KUBELET_EXTRA_ARGS=--cgroup-driver=systemd"
EOF

# enable kubelet
sudo systemctl enable kubelet.service

# enable and start cri-o
sudo systemctl enable --now crio.service
