Documentation

Overview

Package gce allows to use Google Compute Engine (GCE) virtual machines as VMs. It is assumed that syz-manager also runs on GCE as VMs are created in the current project/zone.

See https://cloud.google.com/compute/docs for details. In particular, how to build GCE-compatible images: https://cloud.google.com/compute/docs/tutorials/building-images Working with serial console: https://cloud.google.com/compute/docs/instances/interacting-with-serial-console

Types

type Config

type Config struct {
	Count         int    `json:"count"`          // number of VMs to use
	ZoneID        string `json:"zone_id"`        // GCE zone (if it's different from that of syz-manager)
	MachineType   string `json:"machine_type"`   // GCE machine type (e.g. "n1-highcpu-2")
	GCSPath       string `json:"gcs_path"`       // GCS path to upload image
	GCEImage      string `json:"gce_image"`      // pre-created GCE image to use
