Context Let’s continue with the guide, in this part 2. This is based in: https://github.com/kelseyhightower/kubernetes-the-hard-way/blob/master/docs/03-compute-resources.md Kubernetes Controllers We will be using the following CIDR 192.168.1.0/24 for node within the cluster: Somred1: 192.168.1.50/24 Somred2: 192.168.1.51/24 Somred3: 192.168.1.52/24 Kubernetes Workers This nodes will act as the Kubernetes workers nodes which will host the pods, we need to have 2 NICs for each node. One NIC will be the one used before to communicate with the other nodes: 192....
