Method: machineImages.insert

Creates a machine image in the specified project using the data that is included in the request. If you are creating a new machine image to update an existing instance, your new machine image should use the same network or, if applicable, the same subnetwork as the original instance.

HTTP request

POST https://compute.googleapis.com/compute/beta/projects/{project}/global/machineImages

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.

Query parameters

Parameters
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.

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).
sourceInstance

string

Required. Source instance that is used to create the machine image from.

Authorization requires the following IAM permission on the specified resource sourceInstance:

  • compute.instances.useReadOnly
