Adding Share Access Rules

Function

This API is used to add share access rules.

• This API is an asynchronous API. If the returned status code is 200, the API request is successfully delivered and received. Later, you can refer to Querying Share Access Rules to check whether the share access rule is added successfully.
• APIs whose microversions are from 2.28 to 2.42 can ignore error statuses of existing share access rules during rule adding. The microversions of APIs are specified by using the X-Openstack-Manila-Api-Version parameter in the request headers.

URI

• POST /v2/{project_id}/shares/{share_id}/action?vpc_ip_base_acl={vpc_ip_base_acl}
• Parameter description

  Parameter	Mandatory	Type	Description
  share_id	Yes	String	Specifies the ID of the shared file system.
  project_id	Yes	String	Specifies the project ID of the operator.
  vpc_ip_base_acl	No	String	Specifies the identifier of the IP address-based authorization scenario. Currently, only enable is available. The value enable indicates creating a share access rule for the IP address-based authorization scenario. NOTICE: To ensure compatibility, even though this parameter is left blank or set to another value other than enable, you can use the API to create a share access rule for the IP address-based authorization scenario. However, this method of creation has been discarded and will not be maintained in the future.

Request

• Parameter description

  Parameter	Mandatory	Type	Description
  os-allow_access	Yes	Object	Specifies the os-allow_access object.

  

  If the API version ranges from 1.0 to 2.6, the top-layer parameters of the request body in the JSON format use prefix os-. If the API version is later than 2.6, prefix os- must be removed.

• Description of field os-allow_access

  Parameter	Mandatory	Type	Description
  access_level	No	String	Specifies the access level of the shared file system. Possible values are ro (read-only) and rw (read-write). The default value is rw (read/write).
  access_type	Yes	String	Specifies the storage access mode. For an SFS Capacity-Oriented file system, the value is cert indicating that the certificate is used to access storage.
  access_to	Yes	String	Specifies the value that defines the access rule. The value contains 1 to 255 characters. The value varies according to the scenario: Enter the VPC ID in VPC authorization scenarios. Set this parameter in IP address authorization scenario. Enter the value in the format of VPC ID#IP address#priority#user permission for an NFS shared file system, for example, 0157b53f-4974-4e80-91c9-098532bcaf00#2.2.2.2/16#100#all_squash,root_squash. NOTE: Description of and restrictions on the VPC ID, IP address, priority, and user permission: VPC ID: ID of the VPC. IP address: Tenant IPv4 address or address segment of the ECS's active network port. Each rule only supports one IPv4 address or address segment. The mask format is used to represent an address segment. For example, 192.168.1.0/24 represents the IP address segment of 192.168.1.0 to 192.168.1.255. Other address segment formats, such as 192.168.1.0-255, are not supported. The entered IPv4 address or address segment must be valid and cannot be an IP address or address segment starting with 0 except 0.0.0.0/0. The value 0.0.0.0/0 indicates any IP address in the VPC. In addition, the IP address or address segment cannot start with 127 or 224 to 255, for example, 127.0.0.1, 224.0.0.1, or 255.255.255.255. This is because IP addresses or address segments starting with 224 to 239 are class D addresses and they are used for multicast. IP addresses or address segments starting with 240 to 255 are class E addresses and they are used for research. If an invalid IP address or address segment is used, the access rule may fail to be added or the added access rule cannot take effect. Priority: Priority of a share access rule. It must be an integer ranging from 0 to 100. 0 indicates the highest priority, and 100 indicates the lowest priority. In the same VPC, the permission of the IP address or address segment with the highest priority is preferentially used. For example, if your IP address for mounting is 10.1.1.32, and the authorized 10.1.1.32 (read/write) and 10.1.1.0/24 (read-only) both meet the requirements, the permission of the IP address or segment with the higher priority is used first. If some IP addresses or address segments are of the same priority, one permission of them is randomly chosen. User permission: Set the user permission in the format of allSquash,rootSquash. That is, allSquash is separated from rootSquash using a comma (,). The value of allSquash can be all_squash or no_all_squash. The value of rootSquash can be root_squash or no_root_squash. NOTICE: When creating a shared access rule for the IP address-based authorization scenario, the microversions of the APIs must be 2.28 or later and the vpc_ip_base_acl parameter must be added to the request URL. For details, see the following request example (which varies with the IP address-based authorization scenario). For an ECS in VPC A, its IP addresses can be successfully added to the authorized IP addresses of VPC B, but the file system of VPC B cannot be mounted to this ECS. The VPC used by the ECS and the file system must be the same one.

• Example request (VPC-based authorization)
  When the specified API version ranges from 1.0 to 2.6, the request example is as follows:

  { 
      "os-allow_access": { 
          "access_to": "59cd070d-9c4c-462e-9dcc-b6bb716225bc", 
          "access_type": "cert", 
          "access_level": "rw" 
      } 
  }

  When the specified API version is later than 2.6, the request example is as follows:

  { 
      "allow_access": { 
          "access_to": "59cd070d-9c4c-462e-9dcc-b6bb716225bc", 
          "access_type": "cert", 
          "access_level": "rw" 
      } 
  }
