For the purpose of the training labs, is it OK if I simulate multiple instances by creating new IP aliases on the interface of my VPS? Or would that lead to problems later? I'm at the stage of installing k8s...
Kubernetes is a distributed container manager, and it is dependent on the resources of each cluster node rather than the number of nodes in a cluster.
If multiple instances are an issue, you can run most lab exercises on a single instance (single node cluster), but some steps designed for multi-node clusters will not work. The High Availability configuration in Ch 16 will also not work with a single instance setup.
Understood, thank you.
