Chapter 5. Ansible-based overcloud registration Director uses Ansible-based methods to register overcloud nodes to the Red Hat Customer Portal or to a Red Hat Satellite Server. If you used the rhel-registration method from Red Hat OpenStack Platform versions, you must disable it and switch to the Ansible-based method. For more information, see Switching to the rhsm composable service and RHEL-Registration to rhsm mappings . In addition to the director-based registration method, you can also manually register after deployment. For more information, see Section 5.9, "Running Ansible-based registration manually" 5.1. Red Hat Subscription Manager (RHSM) composable service You can use the rhsm composable service to register overcloud nodes through Ansible. Each role in the default roles_data file contains a OS::TripleO::Services::Rhsm resource, which is disabled by default. To enable the service, register the resource to the rhsm composable service file: The rhsm composable service accepts a RhsmVars parameter, which you can use to define multiple sub-parameters relevant to your registration: You can also use the RhsmVars parameter in combination with role-specific parameters, for example, ControllerParameters , to provide flexibility when enabling specific repositories for different nodes types. 5.2. RhsmVars sub-parameters Use the following sub-parameters as part of the RhsmVars parameter when you configure the rhsm composable service. For more information about the Ansible parameters that are available, see the role documentation . rhsm Description rhsm_method Choose the registration method. Either portal , satellite , or disable . rhsm_org_id The organization that you want to use for registration. To locate this ID, run sudo subscription-manager orgs from the undercloud node. Enter your Red Hat credentials at the prompt, and use the resulting Key value. For more information on your organization ID, see Understanding the Red Hat Subscription Management Organization ID . rhsm_pool_ids The subscription pool ID that you want to use. Use this parameter if you do not want to auto-attach subscriptions. To locate this ID, run sudo subscription-manager list --available --all --matches="*Red Hat OpenStack*" from the undercloud node, and use the resulting Pool ID value. Use a list format to pass multiple IDs to this parameter. rhsm_activation_key The activation key that you want to use for registration. rhsm_autosubscribe Use this parameter to attach compatible subscriptions to this system automatically. Set the value to true to enable this feature. rhsm_baseurl The base URL for obtaining content. The default URL is the Red Hat Content Delivery Network. If you use a Satellite server, change this value to the base URL of your Satellite server content repositories. rhsm_server_hostname The hostname of the subscription management service for registration. The default is the Red Hat Subscription Management hostname. If you use a Satellite server, change this value to your Satellite server hostname. rhsm_repos A list of repositories that you want to enable. rhsm_username The username for registration. If possible, use activation keys for registration. rhsm_password The password for registration. If possible, use activation keys for registration. rhsm_release Red Hat Enterprise Linux release for pinning the repositories. This is set to 8.4 for Red Hat OpenStack Platform rhsm_rhsm_proxy_hostname The hostname for the HTTP proxy. For example: proxy.example.com . rhsm_rhsm_proxy_port The port for HTTP proxy communication. For example: 8080 . rhsm_rhsm_proxy_user The username to access the HTTP proxy. rhsm_rhsm_proxy_password The password to access the HTTP proxy. Important You can use rhsm_activation_key and rhsm_repos together only if rhsm_method is set to portal . If rhsm_method is set to satellite , you can only use either rhsm_activation_key or rhsm_repos . 5.3. Registering the overcloud with the rhsm composable service Create an environment file that enables and configures the rhsm composable service. Director uses this environment file to register and subscribe your nodes. Procedure Create an environment file named templates/rhsm.yml to store the configuration. Include your configuration in the environment file. For example: The resource_registry section associates the rhsm composable service with the OS::TripleO::Services::Rhsm resource, which is available on each role. The RhsmVars variable passes parameters to Ansible for configuring your Red Hat registration. Save the environment file. 5.4. Applying the rhsm composable service to different roles You can apply the rhsm composable service on a per-role basis. For example, you can apply different sets of configurations to Controller nodes, Compute nodes, and Ceph Storage nodes. Procedure Create an environment file named templates/rhsm.yml to store the configuration. Include your configuration in the environment file. For example: The resource_registry associates the rhsm composable service with the OS::TripleO::Services::Rhsm resource, which is available on each role. The ControllerParameters , ComputeParameters , and CephStorageParameters parameters each use a separate RhsmVars parameter to pass subscription details to their respective roles. Note Set the RhsmVars parameter within the CephStorageParameters parameter to use a Red Hat Ceph Storage subscription and repositories specific to Ceph Storage. Ensure the rhsm_repos parameter contains the standard Red Hat Enterprise Linux repositories instead of the Extended Update Support (EUS) repositories that Controller and Compute nodes require. Save the environment file. 5.5. Registering the overcloud to Red Hat Satellite Server Create an environment file that enables and configures the rhsm composable service to register nodes to Red Hat Satellite instead of the Red Hat Customer Portal. Procedure Create an environment file named templates/rhsm.yml to store the configuration. Include your configuration in the environment file. For example: The resource_registry associates the rhsm composable service with the OS::TripleO::Services::Rhsm resource, which is available on each role. The RhsmVars variable passes parameters to Ansible for configuring your Red Hat registration. Save the environment file. 5.6. Switching to the rhsm composable service The rhel-registration method runs a bash script to handle the overcloud registration. The scripts and environment files for this method are located in the core heat template collection at /usr/share/openstack-tripleo-heat-templates/extraconfig/pre_deploy/rhel-registration/ . Complete the following steps to switch from the rhel-registration method to the rhsm composable service. Procedure Exclude the rhel-registration environment files from future deployments operations. In most cases, exclude the following files: rhel-registration/environment-rhel-registration.yaml rhel-registration/rhel-registration-resource-registry.yaml If you use a custom roles_data file, ensure that each role in your roles_data file contains the OS::TripleO::Services::Rhsm composable service. For example: Add the environment file for rhsm composable service parameters to future deployment operations. This method replaces the rhel-registration parameters with the rhsm service parameters and changes the heat resource that enables the service from: To: You can also include the /usr/share/openstack-tripleo-heat-templates/environments/rhsm.yaml environment file with your deployment to enable the service. 5.7. rhel-registration to rhsm mappings To help transition your details from the rhel-registration method to the rhsm method, use the following table to map your parameters and values. rhel-registration rhsm / RhsmVars rhel_reg_method rhsm_method rhel_reg_org rhsm_org_id rhel_reg_pool_id rhsm_pool_ids rhel_reg_activation_key rhsm_activation_key rhel_reg_auto_attach rhsm_autosubscribe rhel_reg_sat_url rhsm_satellite_url rhel_reg_repos rhsm_repos rhel_reg_user rhsm_username rhel_reg_password rhsm_password rhel_reg_release rhsm_release rhel_reg_http_proxy_host rhsm_rhsm_proxy_hostname rhel_reg_http_proxy_port rhsm_rhsm_proxy_port rhel_reg_http_proxy_username rhsm_rhsm_proxy_user rhel_reg_http_proxy_password rhsm_rhsm_proxy_password 5.8. Deploying the overcloud with the rhsm composable service Deploy the overcloud with the rhsm composable service so that Ansible controls the registration process for your overcloud nodes. Procedure Include rhsm.yml environment file with the openstack overcloud deploy command: This enables the Ansible configuration of the overcloud and the Ansible-based registration. Wait until the overcloud deployment completes. Check the subscription details on your overcloud nodes. For example, log in to a Controller node and run the following commands: 5.9. Running Ansible-based registration manually You can perform manual Ansible-based registration on a deployed overcloud with the dynamic inventory script on the director node. Use this script to define node roles as host groups and then run a playbook against them with ansible-playbook . Use the following example playbook to register Controller nodes manually. Procedure Create a playbook that uses the redhat_subscription modules to register your nodes. For example, the following playbook applies to Controller nodes: This play contains three tasks: Register the node. Disable any auto-enabled repositories. Enable only the repositories relevant to the Controller node. The repositories are listed with the repos variable. After you deploy the overcloud, you can run the following command so that Ansible executes the playbook ( ansible-osp-registration.yml ) against your overcloud: This command performs the following actions: Runs the dynamic inventory script to get a list of host and their groups. Applies the playbook tasks to the nodes in the group defined in the hosts parameter of the playbook, which in this case is the Controller group.
