Introduction：The complete definition of the PolarDBXCluster can be found here 。

First, prepare a yaml file that describes the PolarDBXCluster:

apiVersion: polardbx.aliyun.com/v1            # API Group / Version
kind: PolarDBXCluster                                        # API Name
metadata:                                                    # Object metadata

    kind: test

Create the PolarDBXCluster object using the following command:

kubectl create -f polardbx-test.yaml

Observe the status of the PolarDBXCluster object using the following command:

kubectl get pxc polardbx-test
NAME            GMS   CN    DN    CDC   PHASE      DISK   AGE
polardbx-test   0/1   0/2   0/2   0/2   Creating          5s

When the PHASE in the status is Running, the PolarDB-X cluster has been successfully created.

kubectl get pxc polardbx-test
NAME            GMS   CN    DN    CDC   PHASE      DISK   AGE
polardbx-test   1/1   2/2   2/2   2/2   Running    6.2Gi  63s
