使用多個範本

在這個步驟中，您將探索匯入其他範本的範本。

整合這些範本後，設定只需要呼叫單一範本，即可建立具有所有這些資源的部署作業。

開啟網路適用的範本

開啟名為 compute-engine-template.py 的範本：

cd deploymentmanager-samples/examples/v2/step_by_step_guide/step6_use_multiple_templates/python

nano compute-engine-template.py  # use your preferred text editor

這個範本會為部署作業中的所有資源匯入其他範本：虛擬機器 (VM) 適用的 vm-template.py、vm-template-2.py、網路適用的 network-template.py，以及防火牆規則適用的 firewall-template.py。

"""Creates the Compute Engine."""


def GenerateConfig(context):
  """Creates the Compute Engine with network and firewall."""

  resources = [{
      'name': 'vm-1',
      'type': 'vm-template.py'
  }, {
      'name': 'vm-2',
      'type': 'vm-template-2.py'
  }, {
      'name': 'network-1',
      'type': 'network-template.py'
  }, {
      'name': 'firewall-1',
      'type': 'firewall-template.py'
  }]
  return {'resources': resources}

查看設定

開啟部署作業適用的設定檔：

cd deploymentmanager-samples/examples/v2/step_by_step_guide/step6_use_multiple_templates/python

nano config-with-many-templates.yaml  # use your preferred text editor

請注意，設定並未直接呼叫其他範本。不過，仍會匯入其他範本，因為 compute-engine-template.py 取決於其他範本。

imports:
- path: vm-template.py
- path: vm-template-2.py
- path: network-template.py
- path: firewall-template.py
- path: compute-engine-template.py

resources:
- name: compute-engine-setup
  type: compute-engine-template.py

儲存並部署設定

執行下列指令來部署設定：

gcloud deployment-manager deployments create deployment-with-many-templates \
  --config config-with-many-templates.yaml

如要查看部署作業，請執行：

gcloud deployment-manager deployments describe deployment-with-many-templates

預做準備：範本屬性和環境變數

接下來，您會將範本的一些硬式編碼部分替換為可重複使用的模式，例如自訂範本和環境變數。

刪除部署作業

建議您刪除部署作業以免產生費用。下一個步驟不需要用到這個部署作業。執行下列指令以刪除部署作業：

gcloud deployment-manager deployments delete deployment-with-many-templates
