Creating OpenStack tenant

In OpenStack we have several projects where ‘tenant’ is one of them, which is a must for the users and hence is assigned to them. In the following section, let us learn how to create tenant for our users termes as ‘cookbook’.
 
Getting Started
 
First of all, assure that you have logged into our OpenStack Controller host— where OpenStack Identity service has been installed
 
To log  into an OpenStack Controller host that has been  created using Vagrant, subject the following command:
 
vagrant ssh controller
If the keystoneclient tool is not accessible, then it can be installed in an Ubuntu client by declaring the following command say,
sudo apt-get update
sudo apt-get -y install python-keystoneclient
 
Also make sure that our environment has been kept correctly to access our OpenStack environment for organizational objectives:
 
export ENDPOINT = 1172.16.172.200
export SERVICE_TOKEN = ADMIN
export
SERVICE_ENDPOINT = https:// ${ ENDPOINT}: 35357/v2.0

How to carry it out…
 
To create a tenant in our OpenStack environment, perform the following procedure:
1. To Create a tenant called cookbook, do as follows:
keystone tenant-create
–name cookbook
–description “Default Cookbook Tenant”
–enabled true
This entire intput result in an output as below:

Property

Value

DescriptionEnable

Default Cookbook TenantTrue

Id

8ec8e07a759e46d2abb316ee368d0e5b

Name

cookbook

 
2. We must also create another important tenant called ‘admin tenant’, so that all our users can have access to the complete environment available. We achieve it in the similar fashion as above:
 
keystone tenant-create
–name cookbook
–description “Admin Tenant”
–enabled true

How it works…
 
Roles can be created by simply using the keystone client, by specifying the tenant-create option with the help of following syntax:
 
keystone tenant-create
–name tenant_name
–description “A description”
–enabled true
 
The tenant_name is an arbitrary string and hence should not have any spaces. After the completion of creation of tenant we get an ID, which can be used to add further users to this tenant. If you wish to see the list of tenants and the assosciated ID’s in our environment, then we can issue a command as below:
keystone tenant-list
