Configuration

For baremetal and VM based environments, Rafay supports a number of cluster configurations that customers can choose from for their Kubernetes clusters. Some typical configurations are described below.


Dedicated Single Master

In this configuration, the cluster is initially provisioned with two nodes i.e. "one" dedicated master node and "one worker node".

Since the master is a dedicated master, user workloads will not be scheduled on this node. Additional master and worker nodes can be added/removed from this cluster anytime after it is provisioned.

Converged Single Master

In this configuration, the cluster is initially provisioned with one node. i.e. "one" master node that also has a worker node role.

Since this is a converged master, user workloads can also be scheduled on the master node. Additional worker nodes can be added/removed from this cluster anytime after it is provisioned.

Dedicated Multi Master

In this configuration, the cluster is initially provisioned with four nodes. i.e. "three" master nodes forming a highly available, resilient quorum and "one" worker node.

Since this is a dedicated master configuration, user workloads cannot be scheduled on the master nodes. Additional worker nodes can be added/removed from this cluster anytime after it is provisioned.

Converged Multi Master

In this configuration, the cluster is initially provisioned with four nodes. i.e. "three" master nodes forming a highly available, resilient quorum and "one" worker node. All three master nodes also have a worker role.

Since this is a converged master configuration, user workloads can be scheduled on the master nodes as well. Additional worker nodes can be added/removed from this cluster anytime after it is provisioned.
