Deploying with RHSM
|
||||
===================
|
||||
|
||||
Summary
|
||||
-------
|
||||
|
||||
Starting in the Queens release, it is possible to use Ansible to apply the
|
||||
RHSM (Red Hat Subscription Management) configuration.
|
||||
|
||||
Instead of the pre_deploy rhel-registration script, the new RHSM service will
|
||||
allow our operators to:
|
||||
|
||||
#. deploy advanced RHSM configurations, where each role can have their own
|
||||
repositories for example.
|
||||
|
||||
#. use config-download mechanism so operators can run the playbooks at anytime
|
||||
after the deployment, in case RHSM parameters have changed.
|
||||
|
||||
|
||||
Using RHSM
|
||||
----------
|
||||
To enable deployment with Ansible and config-download pass the additional arg
|
||||
to the deployment command::
|
||||
|
||||
openstack overcloud deploy \
|
||||
<other cli args> \
|
||||
-e /usr/share/openstack-tripleo-heat-templates/environments/config-download-environment.yaml \
|
||||
--config-download
|
||||
-e ~/rhsm.yaml
|
||||
|
||||
The ``rhsm.yaml`` environment enables mapping the OS::TripleO::Services::Rhsm to
|
||||
the extraconfig service::
|
||||
|
||||
resource_registry:
|
||||
OS::TripleO::Services::Rhsm: /usr/share/openstack-tripleo-heat-templates/extraconfig/services/rhsm.yaml
|
||||
parameter_defaults:
|
||||
RhsmVars:
|
||||
rhsm_repos:
|
||||
- rhel-7-server-rpms
|
||||
- rhel-7-server-extras-rpms
|
||||
- rhel-ha-for-rhel-7-server-rpms
|
||||
- rhel-7-server-openstack-13-rpms
|
||||
- rhel-7-server-rhceph-3-mon-rpms
|
||||
- rhel-7-server-rhceph-3-tools-rpms
|
||||
rhsm_activation_key: 'secrete-key'
|
||||
|
||||
In some advanced use cases, you might want to configure RHSM for a specific role::
|
||||
|
||||
parameter_defaults:
|
||||
ComputeHCIParameters:
|
||||
RhsmVars:
|
||||
rhsm_repos:
|
||||
- rhel-7-server-rpms
|
||||
- rhel-7-server-extras-rpms
|
||||
- rhel-ha-for-rhel-7-server-rpms
|
||||
- rhel-7-server-openstack-13-rpms
|
||||
- rhel-7-server-rhceph-3-osd-rpms
|
||||
- rhel-7-server-rhceph-3-mon-rpms
|
||||
- rhel-7-server-rhceph-3-tools-rpms
|
||||
rhsm_activation_key: 'anothersecrete-key'
|
||||
|
||||
In that case, all nodes deployed with ComputeHCI will be configured with these RHSM parameters.
|
||||
|
||||
|
||||
Transition from previous method
|
||||
-------------------------------
|
||||
|
||||
The previous method ran a script called rhel-registration during
|
||||
pre_deploy step, which is located in the ``extraconfig/pre_deploy/rhel-registration``
|
||||
folder. While the script is still working, you can perform a
|
||||
migration to the new service by replacing the parameters used in
|
||||
rhel-registration with RhsmVars and switching the resource_registry
|
||||
from::
|
||||
|
||||
resource_registry:
|
||||
OS::TripleO::NodeExtraConfig: rhel-registration.yaml
|
||||
|
||||
To::
|
||||
|
||||
resource_registry:
|
||||
OS::TripleO::Services::Rhsm: /usr/share/openstack-tripleo-heat-templates/extraconfig/services/rhsm.yaml
|
||||
|
||||
The following table shows a migration path from the old
|
||||
rhe-registration parameters to the new RhsmVars:

More about the Ansible role
|
||||
---------------------------
|
||||
|
||||
TripleO is using the Ansible role_ for Red Hat Subscription.

||||
.. _role: https://github.com/openstack/ansible-role-redhat-subscription
|
||||
|
||||
You can find all available parameters in this repository.
