Exploring RBAC authorization

Managing Kubernetes RBAC requires knowledge of a few elements. Specifically, we should learn about Rules, Roles, Subjects, and RoleBindings.

A Rule is a set of operations (verbs), resources, and API groups. Verbs describe activities that can be performed on resources which belong to different API Groups.

Permissions defined through Rules are additive. We cannot deny access to some resources.

Currently supported verbs are as follows:

Verb Description
get Retrieves information about a specific object
list Retrieves information about a collection of objects
create Creates a specific object
update Updates a specific object
patch Patches a specific object
watch Watches for changes to an object
proxy Proxies requests
redirect Redirects requests
delete Deletes a specific object
deletecollection Deletes a collection of objects
