Modifying the operating system only affects subsequently added or reinstalled nodes, and has no impact on the existing nodes' OS.
Within the same cluster, nodes using different versions of the operating system will not affect the cluster's functionality.
A single script may not be suitable for all operating systems. It is recommended that you verify the compatibility of the node's OS with the script after configuring the script for the node.
If you need to use the custom image feature, create custom images using the basic image provided by the container service. For more information, see Custom Image Instructions.
