Creating a RHEL Subscription¶
The PEM web interface allows administrative users to attach Red Hat Subscription Manager information to engines hosted on Red Hat consoles. The Red Hat Subscription Manager tracks installed products and subscriptions to implement content management with tools like yum. For information about Red Hat Subscription Manager, visit the Red Hat website <https://access.redhat.com/documentation/en/red-hat-subscription-management/>.
When you create a new cluster that uses an engine that is associated with a Red Hat subscription, Ark registers the cluster nodes with Red Hat; when you terminate the node, the system’s subcription is unregistered.
To create a RHEL subscription definition, right-click on the RHEL Subscriptions node, and select Create, then RHEL Subscription….
Use fields on the General tab to provide information about the subscription:
- Use the Subscription ID field to provide a user-friendly name for the subscription. The name will identify the subscription in the RHEL Subscription drop-down on the engine details dialog.
- Use the Username field to provide the name of the user account registered with the Red Hat content server.
- Use the Password field to provide the password associated with the user account.
- Use the Server Url field to provide the host name of the subscription server used by the service; if left blank, the default value of subscription.rhn.redhat.com will be used.
- Use the Base Url field to provide the host name of the content delivery server used by the service; if left blank, the default value of https://cdn.redhat.com will be used.
- Use the Organization field to provide the organization that will be registered with the Red Hat subscription system.
- Use the Environment field to provide the name of the environment (within the organization that will be registered).
- Use the System name field to provide the name of the system that will be registered.
Use fields on the Activation tab to provide information about subscription behaviors:
- Use the Activation key field to provide the activation key of the Red Hat subscription.
- When the Auto-attach slider is set to Yes, any node associated with the subscription will automatically attach to the service.
- Use the Pool field to provide the pool identifier for the Red Hat subscription service.
- When the Auto slider is set to Yes, nodes provisioned with engines associated with the pool will automatically attach to the subscription service.
- Use the Quantity selector to specify the number of subscriptions in the subscription pool.
- Use the Service level drop-down listbox to provide the service level of the subscription.
- Use the Release field to provide the operating system minor release that will be used when identifying updates to any nodes provisioned with the subscription.
- When the Force slider is set to Yes, the node will be registered, even if it is already registered.
- Use the Subscription type drop-down listbox to specify the type of consumer that is being registered.
Use fields on the Software/Packages tab to provide information about the software that will be deployed on engines that use the repository:
- The Required repos list is populated by the Ark console, and displays a list of the repositories required by the subscription definition.
- Use the Additional repos field to provide the names of any additional repositories that should be enabled on the cluster node(s).
- Use the Disabled repos field to provide the names of any repositories that should be disabled on the cluster node(s).
