The first code block in the node setup script already correctly modifies and copies the `kubelet-config.yaml` file to each worker node, replacing the "SUBNET" placeholder with the appropriate subnet.
The second code block was redundantly copying the original, unmodified `kubelet-config.yaml` file, overwriting the correctly modified version.
The main purpose of this update is to make sure the guide still works with the newest version of all software. In running through the guide I found places to make bug fixes and minor improvements.
cri-containerd project is moving as a sub-project of containerd itself;
the GitHub migration is complete. Also, as of 9 Jan, the beta.1 release
of cri-containerd is available so the download link is updated.
