Abstract

Assess and remediate system issues by using predefined playbooks provided by the Red Hat Lightspeed tasks service.

Chapter 1. Overview of Red Hat Lightspeed tasks

In Red Hat Lightspeed, the Tasks feature offers predefined playbooks that help you maintain the health of your infrastructure by simplifying and solving complex problems by using automated tasks. Red Hat Lightspeed tasks solve specific problems and are typically run once on your systems to accomplish things such as detecting a high-profile vulnerability on your systems or preparing systems for a major upgrade. You can find tasks in Red Hat Hybrid Cloud Console > Red Hat Lightspeed > RHEL > Automation Toolkit > Tasks in the Red Hat Lightspeed UI.

Red Hat Lightspeed anticipates your need to solve problems and get things done in your infrastructure, and continuously adds specific tasks to the Automation Toolkit.

The pre-built tasks that you can run in Red Hat Lightspeed include:

  • Run the Red Hat Lightspeed client (insights-client)
  • Run the Ansible ping module
  • Pre-conversion analysis for converting to RHEL
  • Convert to RHEL from CentOS Linux 7
  • Pre-upgrade analysis for in-place upgrade from RHEL 8
  • Initiate update of image mode for RHEL host
  • Initiate update of RHEL AI host

To get started with running tasks in Red Hat Lightspeed, review the following important information:

Note

The system requirements to run different tasks can vary.

1.1. User Access settings in the Red Hat Hybrid Cloud Console

User Access is the Red Hat implementation of role-based access control (RBAC). Your Organization Administrator uses User Access to configure what users can see and do on the Red Hat Hybrid Cloud Console (the console):

  • Control user access by organizing roles instead of assigning permissions individually to users.
  • Create groups that include roles and their corresponding permissions.
  • Assign users to these groups, allowing them to inherit the permissions associated with their group’s roles.

1.1.1. Predefined User Access groups and roles

To make groups and roles easier to manage, Red Hat provides two predefined groups and a set of predefined roles:

  • Predefined groups

    The Default access group contains all users in your organization. Many predefined roles are assigned to this group. It is automatically updated by Red Hat.

    Note

    If the Organization Administrator makes changes to the Default access group its name changes to Custom default access group and it is no longer updated by Red Hat.

    The Default admin access group contains only users who have Organization Administrator permissions. This group is automatically maintained and users and roles in this group cannot be changed.

    On the Hybrid Cloud Console navigate to Red Hat Hybrid Cloud Console > the Settings icon (⚙) > Identity & Access Management > User Access > Groups to see the current groups in your account. This view is limited to the Organization Administrator.

  • Predefined roles assigned to groups

    The Default access group contains many of the predefined roles. Because all users in your organization are members of the Default access group, they inherit all permissions assigned to that group.

    The Default admin access group includes many (but not all) predefined roles that provide update and delete permissions. The roles in this group usually include administrator in their name.

    On the Hybrid Cloud Console navigate to Red Hat Hybrid Cloud Console > the Settings icon (⚙) > Identity & Access Management > User Access > Roles to see the current roles in your account. You can see how many groups each role is assigned to. This view is limited to the Organization Administrator.

1.1.2. Access permissions

The Prerequisites for each procedure list which predefined role provides the permissions you must have. As a user, you can navigate to Red Hat Hybrid Cloud Console > the Settings icon (⚙) > My User Access to view the roles and application permissions currently inherited by you.

If you try to access Red Hat Lightspeed features and see a message that you do not have permission to perform this action, you must obtain additional permissions. The Organization Administrator or the User Access administrator for your organization configures those permissions.

Use the Red Hat Hybrid Cloud Console Virtual Assistant to ask "Contact my Organization Administrator". The assistant sends an email to the Organization Administrator on your behalf.

Additional resources

For more information about user access and permissions, see User Access configuration guide for role-based access control (RBAC).

1.1.3. User Access roles for Red Hat Lightspeed tasks users

The following role enables enhanced access to remediations features in Red Hat Lightspeed:

Tasks administrator. The Tasks administrator role permits access to all Tasks capabilities to remotely run tasks on Red Hat Lightspeed-connected systems.

Note

All members of the Default Admin Access group can also run Red Hat Lightspeed tasks.

A Tasks viewer role does not exist in Red Hat Lightspeed.

You can configure the notifications service on the Red Hat Hybrid Cloud Console to send notifications whenever the Red Hat Lightspeed tasks service detects certain events that occur during the start and execution of a task. Use the notifications service as an alternative to continually checking the Activity tab for events related to the status of a task. The notifications service settings are available at Red Hat Hybrid Cloud Console > Settings > Notifications.

When configuring events for Red Hat Lightspeed tasks that you want notifications for, it is essential to understand the distinctions between a task, a task execution, and a task job. Also, be sure to know how they work together to perform a specific task in Red Hat Lightspeed.

  • Red Hat Lightspeed tasks: a predefined script or playbook that helps you perform a specific task.
  • Red Hat Lightspeed tasks execution: an instance of running that script or playbook on one or more systems.
  • Red Hat Lightspeed tasks job: the execution of a specific task on a specific system.

For example, you can configure the notifications service to automatically send an email message when a Red Hat Lightspeed task starts, completes, or fails. As another example, you can configure the notifications service to automatically send an email message when a Red Hat Lightspeed task job starts or completes.

In addition to sending email messages, you can configure the notifications service to send event data in other ways:

  • Using an authenticated client to query Red Hat Lightspeed APIs for event data
  • Using webhooks to send events to third-party applications that accept inbound requests
  • Integrating notifications with applications such as Splunk to route tasks events to the application dashboard, or to your preferred messaging application such as Slack or Microsoft Teams.

Configuring the notifications service to inform members of your Red Hat account of tasks events requires three main steps:

  1. An Organization Administrator creates a User Access group with the Notifications administrator role, and then adds account members to the group.
  2. A Notifications administrator sets up behavior groups for events in the notifications service. Behavior groups specify the delivery method for each notification. The Notifications administrator selects the event types to make available for the specified group of users. For example, a behavior group can specify whether to send email notifications to all users, or just to Organization Administrators.
  3. Members on the account who want to receive email notifications about events must set their user preferences so that they receive individual emails for each event.
Note

To view configurable task events, you must be a Notifications administrator.

For more information about events and notifications, see the additional resources.

Chapter 3. Registering and connecting systems to Red Hat Lightspeed to run tasks

To work with Red Hat Lightspeed, you need to register your RHEL systems and enable system communication with Red Hat Lightspeed. In addition to communicating with Red Hat Lightspeed, you need to enable and install dependencies on Satellite version 6.11 or higher, Remote Host Configuration (rhc), rhc-worker-playbook and ansible, so that you can use task services, and other services in the Automation Toolkit.

For more information about enabling system communication with Red Hat Lightspeed and addressing dependencies, see:

Chapter 4. Running tasks in Red Hat Lightspeed

Red Hat Lightspeed provides built-in task playbooks that you can run on your remote Red Hat Enterprise Linux systems to automate common administrative actions. You can run tasks directly from the Red Hat Lightspeed UI.

  • After you resolve those errors, you can rerun the task from the task status details page within the Automation Toolkit > Tasks > Activity page. The task runs on the same systems as before, but you can also add more systems to the job.

You can use Red Hat Lightspeed to help you convert from CentOS Linux 7 to RHEL 7.

For more information about using Red Hat Lightspeed tasks to help convert your systems, see Converting using Red Hat Lightspeed in the Converting from a Linux distribution to RHEL using the Convert2RHEL utility documentation.

Troubleshooting conversion-related RHEL tasks

Tasks help you update, manage, or secure your RHEL infrastructure by using Red Hat Lightspeed. Each task is a predefined playbook that executes a task from start to finish. For help with conversion-related tasks, see:

Chapter 6. Assessing system-upgrade readiness with the pre-upgrade analysis task

The pre-upgrade analysis task can run on any RHEL 8 system that is connected to Red Hat Lightspeed using the remote host configuration (rhc) solution. The task is a component of the in-place upgrade capability for Red Hat Enterprise Linux, also referred to as the Leapp tool.

For more information about the Leapp tool and using it to check upgrade readiness manually, see Upgrading from RHEL 8 to RHEL 9, Instructions for an in-place upgrade from Red Hat Enterprise Linux 8 to Red Hat Enterprise Linux 9.

You can verify that your system is connected to Red Hat Lightspeed by finding it in System > Inventory.

If not in the inventory, see Remote host configuration and management to learn how to connect systems to Red Hat Lightspeed.

The pre-upgrade analysis task checks the readiness of systems for upgrade from Red Hat Enterprise Linux (RHEL) 8 to RHEL 9. If Red Hat Lightspeed detects upgrade-blocking issues, you can see more information about the issues, including steps to resolve them.

You can also run the Leapp utility manually on systems. When a Red Hat Lightspeed-connected system has a Leapp report in its archive, you can see results from the report in Red Hat Lightspeed, regardless of whether the utility ran manually or as a task that ran from within Red Hat Lightspeed.

Important

The steps in this procedure assume that you have read and understood the following information before you attempt to do any upgrade-related actions by using Red Hat Lightspeed:

Prerequisites

Before you run the pre-upgrade analysis task, ensure the following prerequisites are met:

  • Your systems are eligible for an in-place upgrade. For more information, see the in-place upgrade documentation for system requirements and limitations.

  • Risk to system availability during resolution actions

Prerequisites

You are logged in to the Red Hat Hybrid Cloud Console.

Note

By default, all Red Hat Lightspeed users can view the list of in-place upgrade recommendations.

Procedure

  1. Go to Red Hat Lightspeed > Operations > Advisor > Topics > In-place upgrade to view recommendations affecting the success of in-place upgrades.

    Note

    The in-place upgrade recommendations list only shows recommendations that Red Hat Lightspeed has identified as upgrade inhibitors. You can see all in-place upgrade recommendations, including non-inhibitors, in the detailed view of each executed task.

6.4. Remediating upgrade-inhibiting recommendations

You can use the in-place upgrade recommendations list as a basis for remediating upgrade-inhibiting issues on systems in your infrastructure.

Some recommendations have a playbook available for automating the execution of remediations directly from the Red Hat Lightspeed UI. However, some recommendations require manual resolutions, the steps of which are customized for the system and recommendation pair, and are provided with the recommendation. You can tell which recommendations have playbooks available by viewing the Remediation type column in the recommendations table.

  • To find the recommendations that have playbooks available to execute, use the filter and sort options at the top of the table to narrow down the list.

    • Filter: Use the search bar or select a specific item from the dropdown menu.
    • Sort: Click the Remediation type column header to sort the recommendations by Manual or Playbook types.

For more information about Red Hat Lightspeed remediations, see the Red Hat Lightspeed Remediations Guide.

6.4.1. Remediating RHEL upgrade-inhibiting recommendations with a remediation plan

Automate the remediation of upgrade-inhibiting recommendations by creating a remediation plan in Red Hat Lightspeed. Red Hat Lightspeed generates an Ansible Playbook to execute the necessary actions on selected systems.

Use the following procedure to locate inhibitor issues and select recommendations and systems for remediation.

Prerequisites

  • You are logged in to the Red Hat Hybrid Cloud Console.
  • You are a member of a User Access group with the Tasks administrator role.

  2. Narrow the recommendations list using the table’s filter and sort options:

    1. Filter: Use the search bar or select an item from the dropdown menu.
    2. Sort: Click column headers, for example, Name, Remediation type, Systems, or Total risk.
  3. Choose a recommendation with a Remediation type of Playbook.

    Note

    Recommendations with playbooks are identified by the Remediation type column.

  4. For each recommendation with an available playbook:

    1. Click the recommendation to view details and affected systems.
    2. Check the box next to each system you want to add to the playbook, and then click Plan remediation.
    3. In the pop-up, select Create a new playbook and enter a name, then click Next.
    4. Optional: Alternatively, select the option to add the resolution for the selected systems to an existing playbook in your organization.
    5. Review the included systems and click Next.
    6. Review the included recommendation. You can click the caret next to the recommendation name to see included systems.

      Important

      If the issue or risk requires a reboot, all systems in the remediation plan will automatically reboot. To manually reboot after plan execution, toggle the Auto-reboot button.

    7. Click Submit. The final pop-up view confirms that the playbook was created successfully. You can select to return to the application or open the playbook.
  5. Find and open the playbook in Automation Toolkit > Remediation Plans.
  6. The playbook includes a list of actions. Select the actions to execute by checking the box next to each one.
  7. Click Execute playbook to run the playbook on the specified systems.
  8. When prompted, click Execute playbook on systems. The playbook runs on those systems.

6.4.2. Remediating RHEL upgrade-inhibiting recommendations manually

Some issues cannot be addressed by creating and executing a remediation plan in Red Hat Lightspeed. Instead, they require manual actions or intervention. For example, you can remediate upgrade-inhibiting recommendations by manually applying resolution steps on affected systems.

The following procedure outlines how to determine the resolution steps for a system that Red Hat Lightspeed recommends you manually remediate.

Prerequisites

  • You are logged into the Red Hat Hybrid Cloud Console.

Procedure

  1. Navigate to Operations > Advisor > Topics > In-place upgrade to view recommendations affecting the success of in-place upgrades.
  2. Use the search and filtering function in the table to sort the items by Remediation type.
  3. Choose a recommendation with the word "Manual" in the Remediation type column, which indicates that the issue requires manual remediation.
  4. Click the recommendation name. The full details of the recommendation are displayed, along with a list of impacted systems on the lower part of the page.
  5. For each impacted system:

    1. Expand the caret icon to view the steps to resolve the recommendation.
    2. Complete the recommended actions directly on the system.

Chapter 7. Using Red Hat Lightspeed tasks to update image mode RHEL systems

When building systems by using image mode for RHEL, you can connect your systems to Red Hat Lightspeed. Once connected, use the Red Hat Lightspeed tasks, Initiate an update of your image mode RHEL host, to update your Red Hat Lightspeed-connected systems to the latest versions of RHEL. Red Hat Enterprise Linux version 9.4 and later includes image mode for RHEL.

Note

Image mode for RHEL uses the terms update and upgrade interchangeably.

7.1. Running Red Hat Lightspeed tasks to update image mode for RHEL systems

Red Hat Lightspeed also provides pre-built tasks to help you keep your image mode for Red Hat Enterprise Linux systems updated. From within the Red Hat Lightspeed UI, you can run a task to initiate an update to your image mode for RHEL systems, otherwise known as bootc images.

If you have a large number of image mode for Red Hat Enterprise Linux systems to update, run the Red Hat Lightspeed task titled "Initiate update of image mode for RHEL host" to automate the following actions:

  • Checks the container repository for a new container image
  • Downloads the image and extracts content for use on the next boot
  • Reboots the host to pull in new image content if updated content is available
  • Provides progress results about the image update

You might also want to use this Red Hat Lightspeed task when you want to avoid using the automatic upgrade option for your image mode for Red Hat Enterprise Linux systems.

Important

Image mode for Red Hat Enterprise Linux is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using Technical Preview features in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.
