// HACK(chrboum): This method is a hack. It was written to work around this issue
|
|
// (https://github.com/Azure/azure-sdk-for-go/issues/307) and to an extent this
|
|
// issue (https://github.com/Azure/azure-rest-api-specs/issues/188).
|
|
//
|
|
// Capturing a VM is a long running operation that requires polling. There are
|
|
// couple different forms of polling, and the end result of a poll operation is
|
|
// discarded by the SDK. It is expected that any discarded data can be re-fetched,
|
|
// so discarding it has minimal impact. Unfortunately, there is no way to re-fetch
|
|
// the template returned by a capture call that I am aware of.
|
|
//
|
|
// If the second issue were fixed the VM ID would be included when GET'ing a VM. The
|
|
// VM ID could be used to locate the captured VHD, and captured template.
|
|
// Unfortunately, the VM ID is not included so this method cannot be used either.
|
|
//
|
|
// This code captures the template and saves it to the client (the AzureClient type).
|
|
// It expects that the capture API is called only once, or rather you only care that the
|
|
// last call's value is important because subsequent requests are not persisted. There
|
|
// is no care given to multiple threads writing this value because for our use case
|
|
// it does not matter.
