We recommend you to use API Explorer

Try it

API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

2. Input Parameters

The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

Parameter Name	Required	Type	Description
Action	Yes	String	Common Params. The value used for this API: CreateInstances.
Version	Yes	String	Common Params. The value used for this API: 2018-04-12.
Region	No	String	Common Params. This parameter is not required for this API.
TypeId	Yes	Integer	Instance type `2`: Redis 2.8 Memory Edition (Standard Architecture). `3`: CKV 3.2 Memory Edition (Standard Architecture). `4`: CKV 3.2 Memory Edition (Cluster Architecture). `6`: Redis 4.0 Memory Edition (Standard Architecture). `7`: Redis 4.0 Memory Edition (Cluster Architecture). `8`: Redis 5.0 Memory Edition (Standard Architecture). `9`: Redis 5.0 Memory Edition (Cluster Architecture). `15`: Redis 6.2 Memory Edition (Standard Architecture). `16`: Redis 6.2 Memory Edition (Cluster Architecture).
MemSize	Yes	Integer	Memory capacity in MB, which must be an integer multiple of 1024. For specific specifications, query the sales specifications in all regions through the DescribeProductInfo API. - When TypeId is a standard architecture, MemSize is the total memory capacity of the instance; - When TypeId is a cluster architecture, MemSize is the single-shard memory capacity.
GoodsNum	Yes	Integer	The number of instances for each purchase. For details, query the sales specifications in all regions through the DescribeProductInfo API.
Period	Yes	Integer	The purchase duration of an instance - If `BillingMode` is `1`, that is, when the billing mode is monthly subscription, you need to set this parameter to specify the duration of the purchased instance. Unit: month. Value range: [1,2,3,4,5,6,7,8,9,10,11,12,24,36]. - If `BillingMode` is `0`, that is, when the billing mode is pay-as-you-go, you need to set this parameter to `1`.
BillingMode	Yes	Integer	Billing mode. 0: pay-as-you-go
ZoneId	No	Integer	ID of the AZ where the instance resides. For more information, see Regions and AZs.
Password	No	String	Instance access password - When the input parameter `NoAuth` is `true`, it means that the instance access is set to be password-free, and the `Password` field does not need to be configured; otherwise, `Password` is a required parameter. - When the instance type `TypeId` is Redis 2.8 Memory Edition (Standard Architecture), Redis 4.0, 5.0, 6.0 (regardless of architecture), the password must contains 8-30 characters in at least two of the following types: lowercase letters, uppercase letters, digits, and symbols (()`~!@#$%^&-+=_\|{}[]:;<>,.?/), and it cannot start with a slash (/). - When the instance type TypeId* is CKV 3.2 Memory Edition (regardless of architecture), the password contains 8-30 letters and digits and excludes other characters.
VpcId	No	String	VPC ID. If this parameter is not passed in, the classic network will be selected by default. You can query the specific VPC ID in the VPC console.
SubnetId	No	String	VPC subnet ID. This parameter is not required for the classic network. You can get the specific subnet ID by querying the subnet list in the VPC console.
ProjectId	No	Integer	Project ID. Log in to the Redis console, go to the account information menu in the top-right corner, and select Project Management to query the project ID.
AutoRenew	No	Integer	Auto-renewal flag - `0`: Manual renewal (default). - `1`: Auto-renewal. - `2`: Not auto-renewal (set by user).
SecurityGroupIdList.N	No	Array of String	Array of security group IDs. Get the security group ID of the instance through the DescribeInstanceSecurityGroup API.
VPort	No	Integer	User-defined network port. Default value: `6379`. Range: [1024,65535].
RedisShardNum	No	Integer	Quantity of instance shards - This parameter is not required for instances of Standard Edition. - For instances of Cluster Edition, the range of shard quantity is [1, 3, 5, 8, 12, 16, 24, 32, 40, 48, 64, 80, 96, 128].
RedisReplicasNum	No	Integer	Quantity of instance replicas - For Redis Memory Edition 4.0, 5.0, 6.2 (regardless of architecture), the range of replica quantity is [1,5]. - For Redis 2.8 Standard Edition and CKV Standard Edition, the replica quantity is `1`.
ReplicasReadonly	No	Boolean	Whether to support read-only replicas. - Redis 2.8 Standard Edition and CKV Standard Edition don’t support read-only replicas. - If read-only replicas are enabled, read/write separation will be automatically enabled for an instance, with write requests routed to the master node and read requests to the replica node. - To enable read-only replicas, we recommend that you create two or more replicas.
InstanceName	No	String	Instance name, which can contain up to 60 letters, digits, hyphens, and underscores.
NoAuth	No	Boolean	Whether to support password-free access for an instance - `true`: The instance access is password-free. - `false`: The instance access is password-enabled. Default value: `false`. Only instances in a VPC support the password-free access.
NodeSet.N	No	Array of RedisNodeInfo	The node information of the instance, including node ID, type, and AZ. For more information, see RedisNodeInfo. Node information of an instance. Currently, information about the node type (master or replica) and node AZ can be passed in. This parameter is not required for instances deployed in a single AZ.
ResourceTags.N	No	Array of ResourceTag	The tag for an instance
ZoneName	No	String	Name of the AZ where the instance resides. For more information, see Regions and AZs.
TemplateId	No	String	The parameter template ID associated with the instance - If this parameter is not configured, the system will automatically adapt the corresponding default template based on the selected compatible version and architecture. - Query the list of parameter templates of an instance to get the template ID through the DescribeParamTemplates API.
DryRun	No	Boolean	An internal parameter used to indicate whether to check when creating an instance. - `false`: Default value. Send a normal request and create an instance if all the requirements are met. - `true`: Send a check request and create no instance.
ProductVersion	No	String	The product edition of the instance - `local`: Local Disk Edition. - `cloud`: Cloud Disk Edition. - `cdc`: Dedicated Cluster Edition. Default value: `local`.
RedisClusterId	No	String	Exclusive cluster ID. When `ProductVersion` is set to `cdc`, this parameter is required.
AlarmPolicyList.N	No	Array of String	Alarm policy ID array.- Please log in to Tencent Cloud Observability Platform - Alarm Management - Policy Management to access the alarm policy ID.- If this parameter is not configured, the default alarm policy will be bound. For the specific information about the default alarm policy, please log in to Tencent Cloud Observability Platform - Alarm Management - Policy Management to view.
