Create a cluster

Daria Barysheva

In ADCM a cluster means a set of services running on a set of hosts.

Clusters distributions for ADCM are made in the form of so-called bundles. Generally a bundle is a regular archive that includes a description and software logic of cluster deployment and exploitation.

The steps for adding a cluster to ADCM are listed below.

NOTE
If you use the Enterprise Edition, please, skip the step 1, get a bundle from the Arenadata support team, and move to the step 2.

Step 1. Download a cluster bundle

  1. Go to the Arenadata QuickMarts product website and click Download.

    Switching to the Arenadata QuickMarts downloading page

    Another way — go to https://network.arenadata.io/ and choose Arenadata QuickMarts.

  2. On the next page, download a bundle for the required version of ADQM.

Step 2. Upload a cluster bundle to ADCM

To upload a bundle to ADCM, follow these steps in the ADCM web interface:

  1. Open the BUNDLES tab and click Upload bundle.

  2. Select the downloaded bundle in the Open File Dialog.

    Switching to uploading a bundle

  3. As a result of the performed actions, the uploaded bundle is displayed at the BUNDLES tab.

  4. If you see an exclamation mark in the Edition column, it means that you should sign the license agreement before you start to use the uploaded bundle. Please, click the mark, read the agreement in the opened window, and accept it by clicking Yes.

Step 3. Create a cluster based on the uploaded bundle

IMPORTANT
When creating a cluster via the ADCM web interface, you generate a new ADCM cluster instance. It means only adding the cluster to ADCM — at this stage no services are deployed.

The steps for cluster creation are given below:

  1. Open the CLUSTERS tab and click Create cluster.

    cluster add
    Switching to cluster creation

  2. In the opened dialog, describe a new cluster instance:

    • Select the uploaded cluster bundle in the Bundle field.

    • Select the desired bundle version in the Version field. Several versions become available in the case of different versions of the same bundle being uploaded. By default, the latest version is displayed.

    • Enter the cluster name in the Cluster name field.

    • Enter the cluster description in the Description field, if necessary.

    • Click Create.
