Chapter 1. Introduction to the Identity Service (keystone) As a cloud administrator, you can manage projects, users, and roles. Projects are organizational units containing a collection of resources. You can assign users to roles within projects. Roles define the actions that those users can perform on the resources within a given project. Users can be assigned roles in multiple projects. Each Red Hat OpenStack (RHOSP) deployment must include at least one user assigned to a role within a project. As a cloud administrator, you can: Add, update, and delete projects and users. Assign users to one or more roles, and change or remove these assignments. Manage projects and users independently from each other. You can also configure user authentication with the Identity service (keystone)to control access to services and endpoints. The Identity service provides token-based authentication and can integrate with LDAP and Active Directory, so you can manage users and identities externally and synchronize the user data with the Identity service. 1.1. Resource credential files When you install Red Hat OpenStack Platform director, a resource credentials (RC) file is automatically generated: Source the stackrc file to export authentication details into your shell environment. This allows you to run commands against the local Red Hat OpenStack Platform director API. The name of the RC file generated during the installation of the overcloud is the name of the deployed stack suffixed with 'rc'. If you do not provide a custom name for your stack, then the stack is labeled overcloud . An RC file is created called overcloudrc : The overcloud RC file is referred to as overcloudrc in the documentation, regardless of the actual name of your stack. Source the overcloudrc file to export authentication details into your shell environment. This allows you to run commands against the control plane API of your overcloud cluster. The automatically generated overcloudrc file will authenticate you as the admin user to the admin project. This authentication is valuable for domain administrative tasks, such as creating provider networks or projects. 1.2. OpenStack regions A region is a division of an OpenStack deployment. Each region has its own full OpenStack deployment, including its own API endpoints, networks and compute resources. Different regions share one set of Identity service (keystone) and Dashboard service (horizon) services to provide access control and a web interface. Red Hat OpenStack Platform is deployed with a single region. By default, your overcloud region is named regionOne . You can change the default region name in Red Hat OpenStack Platform. Procedure Under parameter_defaults , define the KeystoneRegion parameter: Replace <sample_region> with a region name of your choice. Note You cannot modify the region name after you deploy the overcloud.
