diskSizeGb

Size of the disk attached to the worker, in GB. See https://cloud.google.com/compute/docs/disks/ If 0 is specified, Cloud Build will use a standard disk size. disk_size is overridden if you specify a different disk size in build_options. In this case, a VM with a disk size specified in the build_options will be created on demand at build time. For more information see https://cloud.google.com/cloud-build/docs/api/reference/rest/v1/projects.builds#buildoptions
