A startup script is a file that contains commands that run when a virtual machine instance boots. Compute Engine provides support for running startup scripts on Linux and Windows virtual machines.
The startup-script.sh could be used as the startup script of a virtual machine instance which run Matter coverage report and publish the result via an App Engine service.
You can create a virtual machine instance by using the gcloud compute instances create command with the --metadata-from-file flag.
gcloud compute instances create VM_NAME \ --image-project=PROJECT_NAME \ --image-family=ubuntu-22.04 \ --metadata-from-file=startup-script=FILE_PATH
Replace the following:
PROJECT_NAME: the name of the project host the virtual machine instance
VM_NAME: the name of the virtual machine instance
FILE_PATH: the relative path to the startup script file
