Chapter 10. Updating overcloud registration to the Red Hat Customer Portal

Red Hat OpenStack Platform 16.1 uses Ansible-based methods to register overcloud nodes to the Red Hat Customer Portal.

10.1. Red Hat Subscription Manager (RHSM) composable service
Copiar enlace

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: 

resource_registry:
  OS::TripleO::Services::Rhsm: /usr/share/openstack-tripleo-heat-templates/deployment/rhsm/rhsm-baremetal-ansible.yaml

The rhsm composable service accepts a RhsmVars parameter, which you can use to define multiple sub-parameters relevant to your registration: 

parameter_defaults:
  RhsmVars:
    rhsm_repos:
      - rhel-8-for-x86_64-baseos-tus-rpms
      - rhel-8-for-x86_64-appstream-tus-rpms
      - rhel-8-for-x86_64-highavailability-tus-rpms
      …​
    rhsm_username: "myusername"
    rhsm_password: "p@55w0rd!"
    rhsm_org_id: "1234567"
    rhsm_release: 8.2

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.

10.2. 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.

rhsmDescription

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.

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 8.2 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.

10.3. Switching to the rhsm composable service
Copiar enlace

The previous 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

  1. 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

  2. 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: 

    - name: Controller
  description: |
    Controller role that has all the controller services loaded and handles
    Database, Messaging and Network functions.
  CountDefault: 1
  ...
  ServicesDefault:
    ...
    - OS::TripleO::Services::Rhsm
    ...
  3. 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: 

resource_registry:
  OS::TripleO::NodeExtraConfig: rhel-registration.yaml

To: 

resource_registry:
  OS::TripleO::Services::Rhsm: /usr/share/openstack-tripleo-heat-templates/deployment/rhsm/rhsm-baremetal-ansible.yaml

You can also include the /usr/share/openstack-tripleo-heat-templates/environments/rhsm.yaml environment file with your deployment to enable the service.

10.5. Registering the overcloud with the rhsm composable service
Copiar enlace

Create an environment file that enables and configures the rhsm composable service. Director uses this environment file to register and subscribe your nodes.

Procedure

  1. Create an environment file named templates/rhsm.yml to store the configuration.

  2. Include your configuration in the environment file. For example: 

    resource_registry:
  OS::TripleO::Services::Rhsm: /usr/share/openstack-tripleo-heat-templates/deployment/rhsm/rhsm-baremetal-ansible.yaml
parameter_defaults:
  RhsmVars:
    rhsm_repos:
      - rhel-8-for-x86_64-baseos-tus-rpms
      - rhel-8-for-x86_64-appstream-tus-rpms
      - rhel-8-for-x86_64-highavailability-tus-rpms
      …​
    rhsm_username: "myusername"
    rhsm_password: "p@55w0rd!"
    rhsm_org_id: "1234567"
    rhsm_pool_ids: "1a85f9223e3d5e43013e3d6e8ff506fd"
    rhsm_method: "portal"
    rhsm_release: 8.2
    • 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.
  3. Save the environment file.

10.6. Applying the rhsm composable service to different roles
Copiar enlace

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

  1. Create an environment file named templates/rhsm.yml to store the configuration.

  2. Include your configuration in the environment file. For example: 

    resource_registry:
  OS::TripleO::Services::Rhsm: /usr/share/openstack-tripleo-heat-templates/deployment/rhsm/rhsm-baremetal-ansible.yaml
parameter_defaults:
  ControllerParameters:
    RhsmVars:
      rhsm_repos:
        - rhel-8-for-x86_64-baseos-tus-rpms
        - rhel-8-for-x86_64-appstream-tus-rpms
        - rhel-8-for-x86_64-highavailability-tus-rpms
        - ansible-2.9-for-rhel-8-x86_64-rpms
        - advanced-virt-for-rhel-8-x86_64-eus-rpms
        - openstack-16.1-for-rhel-8-x86_64-rpms
        - fast-datapath-for-rhel-8-x86_64-rpms
      rhsm_username: "myusername"
      rhsm_password: "p@55w0rd!"
      rhsm_org_id: "1234567"
      rhsm_pool_ids: "55d251f1490556f3e75aa37e89e10ce5"
      rhsm_method: "portal"
      rhsm_release: 8.2
  ComputeParameters:
    RhsmVars:
      rhsm_repos:
        - rhel-8-for-x86_64-baseos-tus-rpms
        - rhel-8-for-x86_64-appstream-tus-rpms
        - rhel-8-for-x86_64-highavailability-tus-rpms
        - ansible-2.9-for-rhel-8-x86_64-rpms
        - advanced-virt-for-rhel-8-x86_64-eus-rpms
        - openstack-16.1-for-rhel-8-x86_64-rpms
        - fast-datapath-for-rhel-8-x86_64-rpms
      rhsm_username: "myusername"
      rhsm_password: "p@55w0rd!"
      rhsm_org_id: "1234567"
      rhsm_pool_ids: "55d251f1490556f3e75aa37e89e10ce5"
      rhsm_method: "portal"
      rhsm_release: 8.2
  CephStorageParameters:
    RhsmVars:
      rhsm_repos:
        - rhel-8-for-x86_64-baseos-tus-rpms
        - rhel-8-for-x86_64-appstream-tus-rpms
        - rhel-8-for-x86_64-highavailability-tus-rpms
        - ansible-2.9-for-rhel-8-x86_64-rpms
        - openstack-16.1-deployment-tools-for-rhel-8-x86_64-rpms
      rhsm_username: "myusername"
      rhsm_password: "p@55w0rd!"
      rhsm_org_id: "1234567"
      rhsm_pool_ids: "68790a7aa2dc9dc50a9bc39fabc55e0d"
      rhsm_method: "portal"
      rhsm_release: 8.2

    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.

  3. Save the environment file.
