Hi,Thanks for your tuto.. I got an error -bash: /etc/containerd/config.toml: Permission denied (with this command sudo containerd config default > /etc/containerd/config.toml)
Hi.
Try this:
sudo containerd config default |sudo tee /etc/containerd/config.toml
Great tutorial but I am getting this error:
This error is likely caused by:
- The kubelet is not running
- The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)
Excellent article! SO hard to find comprehensive instructions for installing k8s, and this one is the exception
