Example 1 with MsoTenantAlreadyExists

use of org.onap.so.openstack.exceptions.MsoTenantAlreadyExists in project so by onap.

the class MsoKeystoneUtils method createTenant.

/**
 * Create a tenant with the specified name in the given cloud. If the tenant already exists, an Exception will be
 * thrown. The MSO User will also be added to the "member" list of the new tenant to perform subsequent Nova/Heat
 * commands in the tenant. If the MSO User association fails, the entire transaction will be rolled back.
 * <p>
 * For the AIC Cloud (DCP/LCP): it is not clear that cloudId is needed, as all admin requests go to the centralized
 * identity service in DCP. However, if some artifact must exist in each local LCP instance as well, then it will be
 * needed to access the correct region.
 * <p>
 *
 * @param tenantName The tenant name to create
 * @param cloudSiteId The cloud identifier (may be a region) in which to create the tenant.
 * @return the tenant ID of the newly created tenant
 * @throws MsoTenantAlreadyExists Thrown if the requested tenant already exists
 * @throws MsoOpenstackException Thrown if the Openstack API call returns an exception
