Deploy a cluster

Connect to ITCare, search for the Global Service to attach the cluster to and click on it.

Click Create resource on the left control panel and select OpenSearch.

Give the cluster a unique name and define a prefix name that will be used to name the virtual machines. Click Next.

Select number of nodes and node size. Click Next.

Select storage volume. Click Next.

Select the region and area to which you want to locate your cluster. Click Next.

Select VLAN you want to deploy your cluster into. Click Next.

Enable or disable additional options:

• Virtual machines and clusters monitoring

• 24/7 monitoring

• Backup

Click Next.

Select the version and define an administrator password that will be used to manage your cluster.

Passwords are not saved by cegedim.cloud. Make sure to save your password.

Verify settings, here you can:

• Check virtual machine names to be created.

• Save your administrator password.

• Modify the management options.

Click Submit.

Once the cluster is ready, you will be notified by email with the information required to connect to the cluster.

Cluster creation can take up to 2 hours based on the current load on automation. The cluster will then be be displayed in your Global Service, in the left control panel, under the related cluster section. The green arrow indicates that the cluster is active.

Start a cluster

Upgrade a cluster

Upgrading a cluster is not yet implemented in ITCare.

If you want to upgrade your existing cluster to a newer available version you must send a request to the support indicating which version you would like.

During the upgrade the OpenSearch cluster will continue to work correctly as we're doing a rolling upgrade. But you might see some short indisponibility during the upgrade of the dashboard servers which is done after the upgrade of the Elastic cluster.
