Creating a Group

Use groups to standardize and unify content across a set of instances in OS Management Hub.

  • On the Groups list page, select Create.

    If you need help finding the list page, see Listing Groups.

    1. Add Basic Details

    Provide the basic information and settings for the group, and then select Next.

    • Group name: Enter a name for the group. You change the name at any time. The name doesn't need to be unique, because an Oracle Cloud Identifier (OCID) uniquely identifies the group. Avoid entering confidential information.
    • Description: (Optional) Enter a description for the group. Avoid entering confidential information.
    • Location: Select the location of the instances in the group. 'Other' is for on-premises or third-party cloud instances.

    • Show advanced options: Add tags to this resource.

      If you have permissions to create a resource, then you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, see Resource Tags. If you're not sure whether to apply tags, ask an administrator or skip this option. You can apply tags later.

    2. Select OS

    Define the OS information for the group, and then select Next.

    • OS vendor: Select the vendor of the OS. For example, Oracle.

    • OS version: Select the version of the OS. For example, Oracle Linux 8.

    • Architecture: Select the architecture for the OS. For example, x86_64.

    • Available Software Sources: For Oracle Linux groups, select the software sources to associate with the group. When an instance joins the group, these software sources will automatically be attached to the instance.

    3. Attach instances (optional)

    Select instances to add to the group. Skip this step to create a group without instances. You can attach or detach instances after the group is created.

    Note

    Available instances match the location, OS vendor, version, and architecture of the group. Offline instances and instances assigned to another group or lifecycle environment aren't listed.
    1. Select a compartment.
    2. Within the Available instances list, select instances to add to the group. Then, select Select instances to attach.
    3. Repeat the preceding steps to select instances from other compartments.
    4. Review the instances and remove any instances from the selection that you don't want added to the group.
    5. Select Next.

    4. Review

    Review the details of the group. Make any changes as needed, and then select Submit.

  • Use the oci os-management-hub managed-instance-group create command and required parameters to create a group.

    oci os-management-hub managed-instance-group create --arch-type architecture --compartment-id ocid --display-name group-name --os-family os-version --software-source-ids software-source-ocids --vendor name [OPTIONS]

    For a complete list of flags and variable options for CLI commands, see the Command Line Reference.

  • Run the CreateManagedInstanceGroup operation to create a group.
