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.

Step 1. Download a cluster bundle

  1. Go to the Arenadata Cluster Manager product website and click Download.

    adcm hostprovider add 01
    Switching to the Arenadata Cluster Manager downloading page

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

  2. On the next page, download a required bundle. Bundles for monitoring clusters are called Monitoring Bundle.

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.

    mon bundle 02 dark
    Switching to uploading a bundle
    mon bundle 02 light
    Switching to uploading a bundle

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

    mon bundle 03
    The result of successful uploading a bundle

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.

    mon cluster add 01
    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.

    mon cluster add 02
    A cluster instance creation

  3. As a result, the created cluster instance is displayed on the CLUSTERS tab.

    mon cluster add 03
    The result of successful creation of a cluster instance
