Parameter description

**Table 1** URI parameter description
Parameter	Mandatory	Description
project_id	Yes	Project ID. For details on how to obtain the project ID, see Obtaining a Project ID.
pageSize	No	Maximum number of clusters displayed on a page Value range: 1 to 2147483646
currentPage	No	Current page number
clusterState	No	You can query a cluster list by cluster status. starting: Query a list of clusters that are being started. running: Query a list of running clusters. terminated: Query a list of terminated clusters. failed: Query a list of failed clusters. abnormal: Query a list of abnormal clusters. terminating: Query a list of clusters that are being terminated. frozen: Query a list of frozen clusters. scaling-out: Query a list of clusters that are being scaled out. scaling-in: Query a list of clusters that are being scaled in.
tags	No	You can search for a cluster by its tag. If you specify multiple tags, the relationship between them is AND. The format of the tags parameter is *tags=k1v1,k2v2,k3v3. When the values of some tags are null, the format is tags=k1,k2,k3v3*.
