Create a domain, projects, users, and roles¶

The Identity service provides authentication services for each OpenStack service. The authentication service uses a combination of domains, projects, users, and roles.

1. Although the “default” domain already exists from the keystone-manage bootstrap step in this guide, a formal way to create a new domain would be:

   $ openstack domain create --description "An Example Domain" example
   
   +-------------+----------------------------------+
   | Field       | Value                            |
   +-------------+----------------------------------+
   | description | An Example Domain                |
   | enabled     | True                             |
   | id          | 2f4f80574fd84fe6ba9067228ae0a50c |
   | name        | example                          |
   | tags        | []                               |
   +-------------+----------------------------------+
   

2. This guide uses a service project that contains a unique user for each service that you add to your environment. Create the service project:

   $ openstack project create --domain default \
     --description "Service Project" service
   
   +-------------+----------------------------------+
   | Field       | Value                            |
   +-------------+----------------------------------+
   | description | Service Project                  |
   | domain_id   | default                          |
   | enabled     | True                             |
   | id          | 24ac7f19cd944f4cba1d77469b2a73ed |
   | is_domain   | False                            |
   | name        | service                          |
   | parent_id   | default                          |
   | tags        | []                               |
   +-------------+----------------------------------+
   

3. Regular (non-admin) tasks should use an unprivileged project and user. As an example, this guide creates the myproject project and myuser user.

   • Create the myproject project:

     $ openstack project create --domain default \
       --description "Demo Project" myproject
     
     +-------------+----------------------------------+
     | Field       | Value                            |
     +-------------+----------------------------------+
     | description | Demo Project                     |
     | domain_id   | default                          |
     | enabled     | True                             |
     | id          | 231ad6e7ebba47d6a1e57e1cc07ae446 |
     | is_domain   | False                            |
     | name        | myproject                        |
     | parent_id   | default                          |
     | tags        | []                               |
     +-------------+----------------------------------+
     

     Note

     Do not repeat this step when creating additional users for this project.

   • Create the myuser user:

     $ openstack user create --domain default \
       --password-prompt myuser
     
     User Password:
     Repeat User Password:
     +---------------------+----------------------------------+
     | Field               | Value                            |
     +---------------------+----------------------------------+
     | domain_id           | default                          |
     | enabled             | True                             |
     | id                  | aeda23aa78f44e859900e22c24817832 |
     | name                | myuser                           |
     | options             | {}                               |
     | password_expires_at | None                             |
     +---------------------+----------------------------------+
     

   • Create the myrole role:

     $ openstack role create myrole
     
     +-----------+----------------------------------+
     | Field     | Value                            |
     +-----------+----------------------------------+
     | domain_id | None                             |
     | id        | 997ce8d05fc143ac97d83fdfb5998552 |
     | name      | myrole                           |
     +-----------+----------------------------------+
     

   • Add the myrole role to the myproject project and myuser user:

     $ openstack role add --project myproject --user myuser myrole
     

     Note

     This command provides no output.
