    Virtual Private Cloud：CreateVpc

    更新時間：Dec 20, 2024

    Creates a virtual private cloud (VPC).

    Operation description

    When you call this operation, take note of the following items:

    • You can specify only one CIDR block for each VPC.

    • After you create a VPC, you cannot change its CIDR block. However, you can add secondary IPv4 CIDR blocks to the VPC.

    • In each VPC, cloud services can use a maximum of 60,000 private IP addresses. You cannot increase the quota.

    • After you create a VPC, a vRouter and a route table are automatically created.

    • At most three user CIDR blocks can be added to a VPC. If a user CIDR block includes another user CIDR block, the one with the shorter subnet mask takes effect. For example, if both 10.0.0.0/8 and 10.1.0.0/16 are specified, only 10.0.0.0/8 takes effect.

    • CreateVpc is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the DescribeVpcAttribute operation to query the status of the task:

      • If the VPC is in the Creating state, the VPC is being created.
      • If the VPC is in the Created state, the VPC is created.

    • You cannot repeatedly call the DeleteRouteEntry operation to create default VPCs within a specific time period. However, you can repeatedly call this operation to create custom VPCs within a specific time period.

    Debugging

    You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

    Authorization information

    The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

    • Operation: the value that you can use in the Action element to specify the operation on a resource.
    • Access level: the access level of each operation. The levels are read, write, and list.
    • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
      • The required resource types are displayed in bold characters.
      • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
    • Condition Key: the condition key that is defined by the cloud service.
    • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

    CidrBlockstringNo

    The CIDR block of the VPC.

    • You can specify one of the following CIDR blocks or their subsets as the primary IPv4 CIDR block of the VPC: 192.168.0.0/16, 172.16.0.0/12, and 10.0.0.0/8. These CIDR blocks are standard private CIDR blocks as defined by Request for Comments (RFC) documents. The subnet mask must be 8 to 28 bits in length.
    • You can also use a custom CIDR block other than 100.64.0.0/10, 224.0.0.0/4, 127.0.0.0/8, 169.254.0.0/16, and their subnets as the primary IPv4 CIDR block of the VPC.

    DryRunbooleanNo

    Specifies whether to perform a dry run, without performing the actual request. Valid values:

    • true: performs only a dry run. The system checks the request for potential issues, including missing parameter values, incorrect request syntax, and service limits. If the request fails the dry run, an error code is returned. If the request passes the dry run, the DryRunOperation error code is returned.
