Element Properties

**Table 1** Property Description
Property	Required	Descripiton
namespace	No	Namespace in a cluster where a resource is located Type: string Value Description: Must be a valid namespace in the cluster, for example, default. Value Constraint: The value must start with a letter. Only lowercase letters, digits, and hyphens (-) are allowed. Suggestion: Log in to the CCE console, and choose Resource Management > Namespaces. View and select the target namespace.
k8sManifest	Yes	Native manifest of the StatefulSet object of the Kubernetes Type: dict Value Description: This field can be customized. You are advised to use a public image (uploading an image to SWR and setting the image type to public). When updating the image, do not change the name and labels under metadata. If replicas under spec is specified using a get_input function, set type to integer. Value Constraint: This field cannot be empty. Suggestion: Customize the value. For details, visit https://kubernetes.io/docs/tutorials/stateful-application/basic-stateful-set/.
clusterId	No	ID of the CCE cluster to which the resource belongs (the cluster version must be 1.7 or later) Type: HuaweiCloud.CCE.Cluster.Id Value Description: Indicates the ID of an existing or new container cluster. Value Constraint: The value must satisfy the UUID rule and support a maximum of 64 characters. Suggestion: Enter the cluster ID. Specifically, log in to the CCE console, and choose Resource Management > Clusters. Click the target cluster, and you can then obtain its cluster ID. Connect to the cluster object and use the get_reference function to obtain the cluster ID.
