|
= Node roles in {product-title}
|
|
|
|
{product-title} assigns hosts different roles. These roles define the function
|
|
of the node within the cluster. The cluster contains standard definitions for
|
|
standard role types, such as bootstrap, master, and worker.
|
|
|
|
A node with the bootstrap role
|
|
provides the initial configuration to clusters and is used only during initial
|
|
configuration.
|
|
|
|
Nodes with the master role run the cluster
|
|
infrastructure and required components. Instead of being grouped into a `MachineSet`,
|
|
they are a series of standalone machine API resources. Extra controls apply to
|
|
master nodes to prevent you from deleting all master nodes and breaking your
|
|
cluster.
|
|
|
|
Nodes with the worker role drive compute workloads. Each type of worker node is
|
|
governed by a specific machine pool that autoscales them.
