Tool: create_flag_release

Creates a FlagRelease resource. Required parameters: 'parent' (e.g. projects/my-project/locations/us-central1), 'flag_release_id', 'flag_release'. Optional parameters: 'validate_only', 'request_id'.

The following sample demonstrate how to use curl to invoke the create_flag_release MCP tool.

Input Schema

The request structure for the CreateFlagRelease method.

CreateFlagReleaseRequest

JSON representation
 { 
 "parent" 
 : 
 string 
 , 
 "flagReleaseId" 
 : 
 string 
 , 
 "flagRelease" 
 : 
 { 
 object (  FlagRelease 
 
) 
 } 
 , 
 "validateOnly" 
 : 
 boolean 
 , 
 "requestId" 
 : 
 string 
 } 
Fields
parent

string

Required. The parent of the flag release.

flagReleaseId

string

Required. The ID value for the new flag release.

flagRelease

object ( FlagRelease )

Required. The desired state for the flag release.

validateOnly

boolean

If "validate_only" is set to true, the service will try to validate that this request would succeed, but will not actually make changes.

requestId

string

An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. The server will guarantee that for at least 60 minutes since the first request.

For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.

The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).

Fields
name

string

Identifier. The resource name (full URI of the resource) following the standard naming scheme:

"projects/{project}/locations/{location}/flagReleases/{flag_release_id}"

flagRevisions[]
(deprecated)

string

Optional. Immutable. DEPRECATED: Use flag_revisions_release instead. FlagRevision s to be rolled out. Only one of flag_revisions, all_flags, or flag_sets can be set. It used to be the ultimate source to truth and has been moved to effective_flag_revisions.

obsoleteFlags[]
(deprecated)

string

Optional. Immutable. Deprecated: Use the 'state' field in the 'Flag' resource to manage the cleanup of flag lifecycles including removal from UnitKind and Units. Flag s to be removed from given UnitKind and all related Units. If Flag is provided here, its FlagRevision s will be removed from UnitKind and Units.

unitKind

string

Required. Immutable. The UnitKind this FlagRelease applies to.

flagSets[]
(deprecated)

string

Optional. Immutable. DEPRECATED: Use flag_sets_release instead. Flag sets to be rolled out. Only one of flag_revisions, all_flags, or flag_sets can be set.

allFlags
(deprecated)

boolean

Optional. Immutable. DEPRECATED: Use all_flags_release instead. Rollout all flags in the provided UnitKind. Only one of flag_revisions, all_flags, or flag_sets can be set.

effectiveFlagRevisions[]

string

Output only. An OUTPUT_ONLY field that contains FlagRevision s to be rolled out. This is the ultimate source of truth of what a Rollout or a UnitOperation carries.

labels

map (key: string, value: string)

Optional. The labels on the resource, which can be used for categorization. similar to Kubernetes resource labels.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" } .

annotations

map (key: string, value: string)

Optional. Annotations is an unstructured key-value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects.

More info: https://kubernetes.io/docs/user-guide/annotations

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" } .

uid

string

Output only. The unique identifier of the resource. UID is unique in the time and space for this resource within the scope of the service. It is typically generated by the server on successful creation of a resource and must not be changed. UID is used to uniquely identify resources with resource name reuses. This should be a UUID4.

etag

string

Output only. An opaque value that uniquely identifies a version or generation of a resource. It can be used to confirm that the client and server agree on the ordering of a resource being written.

createTime

string ( Timestamp format)

Output only. The timestamp when the resource was created.

Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .

updateTime

string ( Timestamp format)

Output only. The timestamp when the resource was last updated. Any change to the resource made by users must refresh this value. Changes to a resource made by the service should refresh this value.

Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .
