Authorization

Overview

Role-based Access Control (RBAC) objects determine whether a user is allowed to perform a given action within a project.

It allows developers to use to control who has access to their projects. Note that authorization is a separate step from authentication, which is more about determining the identity of who is taking the action.

Authorization is managed using:

Rules

Sets of permitted verbs on a set of objects. For example, whether something can create pods.

Roles

Collections of rules. Users and groups can be associated with, or bound to, multiple

Bindings

Associations between users and/or groups with a

The relationships between cluster roles, local roles, cluster role bindings, local role bindings, users, groups and service accounts are illustrated below.

Evaluating Authorization

Several factors are combined to make the decision when {product-title} evaluates authorization:

Identity

In the context of authorization, both the user name and list of groups the user belongs to.

Action

The action being performed. In most cases, this consists of:

Project

The project being accessed.
Verb

Can be get, list, create, update, delete, deletecollection or watch.
Resource Name

The API endpoint being accessed.

Bindings

The full list of bindings.

{product-title} evaluates authorizations using the following steps:

  1. The identity and the project-scoped action is used to find all bindings that apply to the user or their groups.

  2. Bindings are used to locate all the roles that apply.

  3. Roles are used to find all the rules that apply.

  4. The action is checked against each rule to find a match.

  5. If no matching rule is found, the action is then denied by default.
