Getting ready

We will be using the keystone client to operate Keystone. If the python-keystoneclient tool isn't available, follow the steps described at http://bit.ly/OpenStackCookbookClientInstall.

Ensure that we have our environment set correctly to access our OpenStack environment for administrative purposes:

export OS_TENANT_NAME=cookbook
export OS_USERNAME=admin
export OS_PASSWORD=openstack
export OS_AUTH_URL=https://192.168.100.200:5000/v2.0/
export OS_NO_CACHE=1
export OS_KEY=/vagrant/cakey.pem
export OS_CACERT=/vagrant/ca.pem

vagrant ssh controller

How to do it...

To create the required roles in our OpenStack environment, perform the following steps:

How it works...

Creation of the roles is simply achieved by using the keystone client and specifying the role-create option with the following syntax:

keystone role-create --name role_name

The role_name attribute can't be arbitrary for admin and Member roles. The admin role has been set by default in /etc/keystone/policy.json as having administrative rights:

{
 "admin_required": [["role:admin"], ["is_admin:1"]]
}

The Member role is also configured by default in the OpenStack Dashboard, Horizon, for a non-admin user created through the web interface.

On creation of the role, the ID associated with is returned, and we can use it when assigning roles to users. To see a list of roles and the associated IDs in our environment, we can issue the following command:

keystone role-list
