The Select install mode of cluster menu will appear.
There are four options:

• Standalone database
• One-Click Cluster
• Standalone Sharded Cluster
• Sharded Cluster in One-Click

Standalone Database option will create one Primary node only.
::: This option is useful when your task requires only single instance of Database.
One-click Cluster option will create one Primary node and two Secondary/Arbiter nodes.
::: This option is useful when your task requires replication, thus two standbys are created instantly.
Standalone Sharded Cluster option will create one Primary node with configurations, without shards.
Sharded Cluster in One-Click option will create one Primary node, one Secondary/Arbiter node with configurations.

After that select Next and Select the service type - PROXMOX

‍Now you have to select OS version.

The new window will appear: type Replica Set name, create an OS Password and select Next.

The new window will appear: create a Database Password.
In this window you can choose the Сluster size: small, medium or large.
Click on the Rest API icon.

• You can paste generated code for use in automation in your preferred DevOps tool.

Finally, select Submit to finalize your installation.
