API

A set of comprehensive APIs are available that enable the users to seamlessly create, update, retrieve cluster details (list, and status) and delete V3 MKS Clusters. The API allows you to easily manage the cluster by providing the project id and resource name

---

Create Cluster

To create a new cluster (or) update an existing cluster config in a specific project:

• Provide the project name and the new/updated schema for the resource
• Click execute

Below is an example of a cluster schema updating the blueprint to 'default'.

---

Cluster List

To view the list of clusters in a specific project, provide the project name and click execute. Below is an example of the cluster list output:

Get Cluster Installer Command

The Get Cluster InstallerCmds API endpoint returns a command that needs to be executed on MKS nodes. This command facilitates the discovery and integration of these nodes with Rafay's platform. This serves as a setup wizard to configure nodes for management and operations via Rafay's infrastructure. After obtaining this command from the API, it should be copied and executed on each customer node to enable communication with Rafay's services.

To get the installer command, - Provide the project name and cluster name - Click Execute

Below is an example of the output that shows the command for arm64 with OSFamily linux.

Scroll down to get the command for amd64 with OSFamily linux.
