Parameter	Type	Description
client-certificate-data	String	Client certificate.
client-key-data	String	Contains PEM encoding data from the TLS client key file.

Table 8 Data structure of the contexts field

Parameter	Type	Description
name	String	Context name. If the publicIp parameter does not exist (that is, no EIP exists), there is only one cluster in the cluster list, and the value of this parameter is internal. If the publicIp parameter exists (that is, the EIP exists), there is more than one cluster in the cluster list, and the value of this parameter is external.
context	context <cce_02_0359_0__table47913919518> object	Context information.

Table 9 Data structure of the context field
