Role-based access control is an approach to restricting system access to authorized users. Kubernetes supports multiple authorization modules, including role-based access control, which works using Role, ClusterRole, RoleBinding, and ClusterRoleBinding objects, which are declared using RBAC API. In this course, you’ll explore the concept of authorization and the authorization modes supported by Kubernetes. You’ll investigate how to control access to the Kubernetes API server, including the prominent principles for planning and implementing Kubernetes role-based access control, the features of Role, ClusterRole, RoleBinding, and ClusterRoleBinding objects. Next, you’ll utilize kubectl subcommands and commands to query the API authorization layer, enable the NamespaceLifecycle and LimitRanger admission control plugins, and get a list of existing Roles, ClusterRoles, RoleBindings, and ClusterRoleBindings from Kubernetes clusters. You’ll then create a file and use it to create a Role, ClusterRole, RoleBinding, and ClusterRoleBinding. Next, you’ll create kubeconfig files to allow users to perform operations in Kubernetes cluster Namespaces. Finally, you’ll implement Aggregated ClusterRole and use the AggregationRule to define label selectors and match other ClusterRole objects.

WHAT YOU WILL LEARN

  • discover the key concepts covered in this course
    describe the concept of authorization in Kubernetes along with the authorization modes supported by Kubernetes API server
    recall the steps and stages to control access to the Kubernetes API server with a focus on authentication, authorization, admission control, and validation
    use the kubectl subcommands to query the API authorization layer and enable the NamespaceLifecycle and LimitRanger admission control plugins
    recall the prominent principles that can help plan and implement Kubernetes role-based Access Control
    recognize the features of the Role, ClusterRole, RoleBinding, and ClusterRoleBinding objects of the RBAC API that help implement role-based access control in Kubernetes infrastructure
    create a file and use it to create a role in the default Namespace in order to grant get, watch, and list access to pods
  • create a file and use it to create a RoleBinding in the default Namespace in order to facilitate a Pod reader role for users
    create a file and use it to create a ClusterRole in order to grant get, watch, and list access to secrets in any particular Namespace and across all Namespaces
    create a file and use it to create a ClusterRoleBinding in order to allow any user in the Group Manager to read secrets in any Namespace
    work with kubectl commands to get a list of existing Roles, ClusterRoles, RoleBinding, and ClusterRoleBindings from Kubernetes clusters
    create kubeconfig files to allow particular users to perform operations in particular Namespaces of Kubernetes clusters
    create a configuration file to implement aggregated ClusterRoles and use AggregationRule to define label selectors that the controller can use to match other ClusterRole objects
