How deeply does Google Anthos in Action cover RoleBinding?

Defines namespace scope and binding relationships, but does not detail manifest structure or creation commands.

RoleBinding

A RoleBinding is a Kubernetes RBAC resource that grants the permissions of a role to users, groups, or service accounts within a namespace.

A RoleBinding grants the permissions defined by a Role to users, groups, or service accounts within the RoleBinding’s namespace. Roles define permissions but do not assign them; the binding performs that assignment. section 3.2.6

Understand RoleBinding through its scope and relationship to other RBAC resources:

A RoleBinding created in a namespace can assign permissions only within that namespace. section 3.2.6
A RoleBinding can bind either a namespace-scoped Role or a ClusterRole used at namespace scope. section 3.2.6
A ClusterRoleBinding provides the contrasting cluster-wide binding scope. section 3.2.6

Table 3.7 Binding types and their scopes (view table figure)

Binding type	Scope	Description
RoleBinding	Namespace	Can be used to assign permissions only in the namespace in which it was created
ClusterRoleBinding	Cluster	Can be used to assign permissions cluster wide

Compare RoleBinding and ClusterRoleBinding by scope and permission-assignment behavior. section 3.2.6
