Add components

In ADCM a component means a part of a service that should be deployed on one or several cluster hosts.

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

    All components of ADQM Control services are mandatory (highlighted in red). The ADCM UI also displays how many components should be installed.

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

    TIP
    It is recommended to install the Arenadata PostgreSQL component on a dedicated host, separately from the components of the ADQM Control service.

    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.
