cluster-admin role¶

The cluster-admin role is a built-in, pre-defined role in Kubernetes that grants full administrative permissions across the entire cluster^[dashboatd.install.md]. This role is created by Kubernetes by default, eliminating the need for administrators to manually define or create it to gain full system control^[dashboatd.install.md].

Usage and Binding¶

Because this role exists by default, users can immediately reference it within RoleBinding or ClusterRoleBinding configurations to grant superuser access^[dashboatd.install.md].

A common use case involves creating a ClusterRoleBinding that references cluster-admin in the roleRef section^[dashboatd.install.md]. For example, to grant a specific service account administrative privileges, the binding configuration specifies kind: ClusterRole and name: cluster-admin^[dashboatd.install.md].
