이 예시의 기본 도우미 스크립트는 가상 머신(VM)의 이름을 생성합니다. 스크립트를 보려면 다음 명령어를 실행합니다.
cddeploymentmanager-samples/examples/v2/step_by_step_guide/create_a_helper_script
nanocommon.py# use your preferred text editor
GenerateMachineName() 함수는 프리픽스와 서픽스를 사용하고 prefix-suffix 형식으로 된 이름을 생성합니다.

템플릿에서 도우미 스크립트 사용
vm-template.py에서 common.py를 사용하려면 템플릿에서 몇 가지를 변경해야 합니다.
변경사항을 보려면 vm-template.py를 엽니다.
nanovm-template.py
템플릿에 변경사항을 강조하는 코드 주석이 있습니다.
템플릿은 파일 맨 위에서 common.py를 가져옵니다.
이제 resources 섹션에서 VM의 name 필드가 GenerateMachineName()을 호출합니다.

For example, you can\nuse helper scripts to interpret resource metadata, create files, and launch\nservices.\n\nYou will now explore a Python helper script that names a virtual machine, given\na prefix and a suffix.\n\nBefore you begin\n----------------\n\n- If you want to use the command-line examples in this guide, install the [\\`gcloud\\` command-line tool](/sdk).\n- If you want to use the API examples in this guide, set up [API access](/deployment-manager/docs/reference/latest).\n\nOpening the helper script\n-------------------------\n\nThe basic helper script in this example generates the name for a virtual machine\n(VM). To view the script, run these commands: \n\n cd deploymentmanager-samples/examples/v2/step_by_step_guide/create_a_helper_script\n\n nano common.py # use your preferred text editor\n\nThe `GenerateMachineName()` function takes a prefix and suffix, and generates a\nname in the format `prefix-suffix`: \n\n \"\"\"Generates name of a VM.\"\"\"\n\n\n def GenerateMachineName(prefix, suffix):\n return prefix + \"-\" + suffix\n\nUsing the helper script in the template\n---------------------------------------\n\nTo use `common.py` in `vm-template.py`, several changes must be made to the\ntemplate.\n\nTo view the changes, open `vm-template.py`: \n\n nano vm-template.py\n\nThe template contains code comments that highlight the changes.\n\nNote that the template imports `common.py` at the top of the file.\nIn the `resources` section, the `name` fields for the VMs now call\n`GenerateMachineName()`. \n\n \"\"\"Creates the virtual machine.\"\"\"\n\n # `common.py` is imported below.\n import common\n\n COMPUTE_URL_BASE = 'https://www.googleapis.com/compute/v1/'\n\n\n def GenerateConfig(context):\n \"\"\"Generates configuration of a VM.\"\"\"\n resources = [{\n 'name': common.GenerateMachineName('myfrontend', 'prod'),\n 'type': 'compute.v1.instance',\n 'properties': {\n 'zone': 'us-central1-f',\n 'machineType': COMPUTE_URL_BASE + 'projects/' + context.env['project']\n + '/zones/us-central1-f/machineTypes/f1-micro',\n 'disks': [{\n 'deviceName': 'boot',\n 'type': 'PERSISTENT',\n 'boot': True,\n 'autoDelete': True,\n 'initializeParams': {\n 'sourceImage': COMPUTE_URL_BASE + 'projects/'\n 'debian-cloud/global/images/family/debian-11'}\n }],\n 'networkInterfaces': [{\n 'network': COMPUTE_URL_BASE + 'projects/' + context.env['project']\n + '/global/networks/default',\n 'accessConfigs': [{\n 'name': 'External NAT',\n 'type': 'ONE_TO_ONE_NAT'\n }]\n }]\n }\n }]\n return {'resources': resources}\n\nViewing the changes to the configuration\n----------------------------------------\n\nTo view the updated configuration, open `two-vms.yaml`: \n\n nano two-vms.yaml\n\nNote that the helper script `common.py` must be imported in the configuration\nas well.\n\nDeploy your configuration: \n\n gcloud deployment-manager deployments create deployment-with-helper-script --config two-vms.yaml\n\nTo view the deployment, including the resources with the generated names, run: \n\n gcloud deployment-manager deployments describe deployment-with-helper-script\n\nDeleting your deployment\n------------------------\n\nWe recommend that you delete the deployment to avoid charges. You don't need\nthis deployment for the next step. Run the following command to delete the\ndeployment: \n\n gcloud deployment-manager deployments delete deployment-with-helper-script\n\nLooking ahead: updating deployments\n-----------------------------------\n\nNext, learn to add, delete, and change the properties of resources in a\ndeployment as your app evolves."]]
