Attaching an Instance to a Group

Add an instance to a group in OS Management Hub so that it receives the same content as all other members of the group.

Tip

Registering new instances? Create a group profile to automatically attach instances to the group when they register.

Before attaching instances, review the Service Limits. The default limit is 1,000 managed instances per group, including instances attached automatically through a group registration profile. If you need a larger group, create a support request for an increase before attaching instances. See Service Limits for the information to provide in your request.

  • Select instances to attach

    1. Select the compartment for the instance you want to attach.
    2. Select one or more instances to add to the group, and then select Attach.
      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.
    3. Repeat the preceding steps to select instances from other compartments.

    Review

    1. Review the selected instances.
    2. To remove instances, select them and select Remove instances from selection.
    3. If the list of selected instances looks good, select Attach.

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

    oci os-management-hub managed-instance-group attach-managed-instance --group-id ocid --managed-instances instances.json [OPTIONS]
