Creating a cluster
A cluster is a group of servers in a single location. The key feature of such servers (cluster nodes) is their location and high data transfer speed between them.
Perform the following steps to create a cluster:
- Go to Clusters → Create a cluster.
Select the cluster Technology type — KVM or LXD.
- Enter a cluster Name or press generate.
- Set the Time zone that will be used for cluster nodes and virtual machines (VMs) by default.
- Enter optional Notes.
- Click Next.
- Select the OS that can be installed on virtual machines in the cluster.
- Enable the option Users can upload their ISO-images to allow VM owners to connect their own ISO images to the VM. Read more in the article Mounting an ISO image.
- Select the Domains Template for VMs in this cluster. For example, if you specify the template .example.com, when you create a VM in this cluster, it will have a domain of the form vm_name.example.com.
- Enable the option Users can change a domain name to allow VM owners to change domain names.
- Enter the RAM overselling rate in the node. Read more in the article Overselling.
- Specify the VM limit on nodes — the maximum number of VMs that will be created on cluster nodes.
- Select the type of Distribution of VM on nodes:
- homogeneous — VMs will be created on the most vacant node of the cluster;
- successive — VMs will be created on the node of the cluster that is filled up the most. Read more about node selection in Selecting a cluster node for the virtual machine.
- Click Next.
- Specify the Storage settings rules on nodes. Read more in the article Storage types:
- Images and backups directory. Default value is /image.
- OS directory. Default value is /share.
- Images and backups directory. Default value is /image.
To edit the default storage settings, press .To add a storage, click and specify its settings :
Click main to use the added storage as primary.
Storage configuration interface
- If a storage for backups is connected to the platform, select it in the Backup location field. For more information about connecting storage, see the article Backup storage.
- Click Next.
Select a Network configuration type:
- Click on Create.
