Kubernetes Cluster (3 mastersprimary servers)
3 On private clouds (vSphere and OpenStack), each of the 3 master primary server instances require 3 vCPU and 8 GB memory and 40 GB storage (root disk), hence the difference in the additional requirement of 9 vCPU, 24 GB memory, and 120 GB storage (root disk). See the Number of VMs section below for additional details. Similarly, each worker instances require 3 vCPU and 8 GB memory and 40 GB storage (root disk) – however, the number of workers changes dynamically at install time. Installer VMs require a minimum of 4 vCPUs and 8 GB RAM.
A CloudCenter Suite installation launches a highly available Kubernetes cluster which consists of masterprimary server(s) and worker(s) instances.
For private clouds, a redundant cluster requires a minimum of 2 out of 3 master primary server nodes to be running at any point, so the cluster can function as designed.
Verify if the IP pool can accommodate additional workloads.
Select your instance type according to the following dependencies – based on your instance type selection, the installer displays the error or success information in the UI.
The CloudCenter Suite setup requires 3 mastersprimary servers.
The CloudCenter Suite dynamically calculates the number of application VMs (workers).
Do not use 172.18.0.1/16 for the installer instance as this IP address is used by the Docker/Kubernetes setup.
NodePort: If you set the type field to NodePort, the Kubernetes control plane allocates a port from a range specified by – service-node-port-range flag (default: 30000-32767). Refer to https://kubernetes.io/docs/concepts/services-networking/service/ for additional details.
The time for all worker and master primary server nodes is synced with the primary master controller node. The primary master controller node is the instance used to launch the CloudCenter Suite – identified by the link that takes you to the Suite Admin UI (Take Me to Suite Admin). This link contains the IP address of the primary master controller node as displayed in the following screenshot.
