For instructions regarding creation and registration of a GPG key for Ubuntu Core model signing (the name of which you assign to the SNAPCRAFT_KEY_NAME variable in the preceding command), see https://ubuntu.com/core/docs/sign-model-assertion. To build a local Azure gadget snap, see https://github.com/danpdraper/pc-gadget/tree/azure. To obtain your Snapcraft credentials (in the interest of assigning those credentials to the SNAPCRAFT_STORE_CREDENTIALS variable in the preceding command), see https://ubuntu.com/core/docs/create-ubuntu-one#heading--snapcraft-credentials.
To convert the raw image to a fixed-size VHD, and then publish that VHD to Azure, run the following from this repository's root:
