Querying DB Instances

Function

This API is used to query DB instances according to search criteria. Before using this API:

• Learn how to authorize and authenticate it.
• Obtain the required region and endpoint.

URI

GET /v3/{project_id}/instances

Table 1 URI parameters

Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID of a tenant in a region. To obtain this value, see Obtaining a Project ID.

Table 2 Query parameters

Parameter	Mandatory	Type	Description
id	No	String	DB instance ID. The asterisk (*) is reserved for the system. If the DB instance ID starts with *, it indicates that fuzzy match is performed based on the value following *. Otherwise, the exact match is performed based on the DB instance ID. The value cannot contain only asterisks (*).
name	No	String	DB instance name. The asterisk (*) is reserved for the system. If the instance name starts with *, it indicates that fuzzy match is performed based on the value following *. Otherwise, the exact match is performed based on the instance name. The value cannot contain only asterisks (*).
type	No	String	DB instance type to be queried. Currently, its value can only be Cluster.
datastore_type	No	String	DB type. Currently, only gaussdb-mysql is supported.
vpc_id	No	String	VPC ID. Method 1: Log in to VPC console and view the VPC ID in the VPC details. Method 2: See the "Querying VPCs" section in the Virtual Private Cloud API Reference.
subnet_id	No	String	Network ID of the subnet. Method 1: Log in to VPC console and click the target subnet on the Subnets page. You can view the network ID on the displayed page. Method 2: See the "Querying Subnets" section under "APIs" or the "Querying Networks" section under "OpenStack Neutron APIs" in the Virtual Private Cloud API Reference.
private_ip	No	String	Private IP address.
offset	No	Integer	Index offset. If offset is set to N, the resource query starts from the N+1 piece of data. The value is 0 by default, indicating that the query starts from the first piece of data. The value cannot be a negative number.
limit	No	Integer	Number of records to be queried. The default value is 100. The value must be a positive integer. The minimum value is 1 and the maximum value is 100.
tags	No	String	Query based on the DB instance tag key and value. {key} indicates the tag key, and {value} indicates the tag value. To query DB instances with multiple tag keys and values, separate key-value pairs with commas (,). The key must be unique. Multiple keys are in AND relationship.

Request Parameters

Table 3 Request header parameters
