Create a private hook version

Function

CreatePrivateHookVersion

Create a private hook version. After creating a private hook version, you need to call UpdatePrivateHook API to set it as the default version for it to take effect.

The hook_version must follow the Semantic Version and is customized by the user. Each component (Major.Minor.Patch) is an unsigned 64-bit integer (uint64).
If both hook_name and hook_id are provided, RFS checks whether they match. If hook name does not match the current private hook ID, error code 400 is returned.
RFS performs validations on private hooks, such as file size checks and policy document syntax validation. If any errors are found, the creation of the hook will fail.

URI

POST /v1/private-hooks/{hook_name}/versions

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
hook_name	Yes	String	Private hook name. The name is unique within its domain (domain_id) and region. It can contain Chinese characters, uppercase and lowercase letters, digits, underscores (_), and hyphens (-). The first character must be a Chinese or English character. It is case sensitive. Minimum: 1 Maximum: 128

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
Client-Request-Id	Yes	String	Unique request ID. It is specified by a user and is used to locate a request. UUID is recommended. Minimum: 36 Maximum: 128

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
hook_id	No	String	Unique ID of a private hook. It is an UUID generated by RFS when a private hook is created. Private hook names are unique only at one specific time, so you can create a private hook named helloWorld and another private hook with the same name after deleting the first one. For parallel development in a team, users may want to ensure that the private hook they operate is the one created by themselves, not the one with the same name created by other teammates after deleting the previous one. Therefore, they can use this ID for strong matching. RFS ensures that the ID of each private hook is different and does not change with updates. If the hook_id value is different from the current private hook ID, error code 400 is returned. Minimum: 36 Maximum: 36
hook_version	Yes	String	Private hook version. The version number follows the Semantic Version and is customized by the user. Each component (Major.Minor.Patch) is an unsigned 64-bit integer (uint64). Minimum: 5 Maximum: 128
hook_version_description	No	String	Description of the private hook version. It can be used by users to identify and manage private hook versions. Note: The private hook version is immutable, so the description cannot be updated. If it needs to be updated, please delete private hook version and rebuild it. Minimum: 0 Maximum: 1024
policy_uri	No	String	OBS address of the policy file. The content must be written in the Rego language, which is recognizable by the open-source OPA (Open Policy Agent) engine, as described in the documentation at https://www.openpolicyagent.org/docs/latest/policy-language/. Ensure that the OBS address is located in the same region as the RFS. The policy file can be a single file or a .zip package. A single file must end with .rego. A .zip package must end with .zip. The policy file verification requirements are as follows: Files must be UTF8 encoded During creation, validations are performed for size, format, syntax, etc. The policy file must be in UTF-8 encoding format. The size of a single file or compressed package before and after decompression must be less than 1 MB. The number of files in the compressed package cannot exceed 100. The maximum length of file paths in the compressed package is 2048 characters. The maximum length of the policy file name in the compressed package is 255 bytes. Either policy_uri or policy_body must be specified. Minimum: 0 Maximum: 2048
policy_body	No	String	Policy content. The content must be written in the Rego language, which is recognizable by the open-source OPA (Open Policy Agent) engine, as described in the documentation at https://www.openpolicyagent.org/docs/latest/policy-language/. Either policy_uri or policy_body must be specified. Minimum: 0 Maximum: 51200
