Add components

Anton Vasilev

In ADCM, a component means a part of a service that should be deployed on one or several cluster hosts. For example, the ADB Control service consists of the ADB Control Server, ADB Control UI, ADB Control Scheduler, and ADB Control Migration components.

IMPORTANT
Initially, there are no components on any of cluster hosts. You should map components to hosts manually.

The steps for adding components to hosts are listed below:

  1. Select a cluster on the Clusters page. To do this, click a cluster name in the Name column.

    Select a cluster
    Select a cluster

  2. Open the Mapping tab on the cluster page.

    Switch to mapping components to hosts
    Switch to mapping service components

  3. In the window that opens, map components to hosts. To assign hosts for each component, click Add hosts and select hosts in the pop-up window.

    Select hosts for a component
    Select hosts for a component
    Mandatory components

     
    Each service can have mandatory and optional components. Mandatory components are highlighted in red. The ADCM UI also displays how many mandatory components should be installed.

    CAUTION
    Without assigning a necessary number of hosts to mandatory components, the component mapping cannot be saved.

    Any of the ADB ES components can be installed on a separate host, or you can install all of them on a single host. It is highly recommended to install ADB ES components on a host separate from ADB.

  4. After component distribution is completed, click Save.

    Save mapping of components
    Save mapping of components

Starting with ADCM 2.2.0, you can use another mapping mode — by hosts. To do this, switch on the Hosts mode toggle and map components to hosts by clicking Add components for each host sequentially.
