Roles

This page describes Roles in Lenses.

Lenses IAM is role-based. Roles contain one or more policies. Each policy defines actions a user is allowed to perform on resources.

Roles are then assigned to groups.

Role Policies

Policies are resource-based. They are YAML documents attached to a role.

Each policy has:

1. Action
2. Resource
3. Effect

The resource is the name of the resource. This is defined by the creator of the resource.

Action

The action describes the action or verb that a user can perform. The format of the action is

service:operation

For example, to list topics in Kafka:

policy:
  - action:
      - kafka:ListTopics

For a full list of the actions see Permission Reference.

To allow all actions set '*'

Resource

Resources scope a policy to specific entities. For example, to only allow topics that start with red, use the resource field.

For a full list of the actions see Permission Reference.

To allow all actions set '*'

Effect

Effect is either allow the action on the resource or deny. If allow is not set the action will be denied and if any policy for a resource has a deny effect it takes precedence.

Create a Role

To create a role, go to IAM → Roles → New Role.
