Cloud Deployment Manager dejará de estar disponible el 31 de diciembre de 2025. Si actualmente usas Deployment Manager, migra a Infrastructure Manager o a una tecnología de implementación alternativa antes del 31 de diciembre de 2025 para asegurarte de que tus servicios continúen sin interrupciones.
Usa variables de entorno específicas de la implementación
Organiza tus páginas con colecciones
Guarda y categoriza el contenido según tus preferencias.
Para cada una de tus implementaciones, Deployment Manager crea variables de entorno predefinidas que contienen información deducida de tu implementación.
Usa estas variables de entorno en tus plantillas de Python o Jinja2 para obtener información sobre tu proyecto o implementación.
Deployment Manager configura las siguientes variables del entorno automáticamente.
Se las reemplaza en cualquier lugar que las utilices en tus plantillas. Por ejemplo, usa la variable project_number para agregar el número de proyecto al nombre de una cuenta de servicio.
Variable de entorno
Valor
deployment
El nombre de la implementación.
name
El name declarado en la configuración que utiliza la plantilla. Esta variable puede ser útil si quieres que el nombre que declaras en la configuración sea el mismo del recurso en las plantillas subyacentes.

For example,\nuse the `project_number` variable to add the project number to the name of a\nservice account.\n\nUsing an environment variable\n-----------------------------\n\nUse the following syntax to add an environment variable to your templates: \n\n```django/jinja\n{{ env[\"deployment\"] }} # Jinja\n\ncontext.env[\"deployment\"] # Python\n```\n\nIn your template, use the variables as in these examples: \n\n### Jinja\n\n```django/jinja\n- type: compute.v1.instance\n name: vm-{{ env[\"deployment\"] }}\n properties:\n machineType: zones/us-central1-a/machineTypes/f1-micro\n serviceAccounts:\n - email: {{ env['project_number'] }}-compute@developer.gserviceaccount.com\n scopes:\n - ...\n```\n\n### Python\n\n```python\ndef GenerateConfig(context):\n resources = []\n resources.append ({\n 'name': 'vm-' + context.env[\"deployment\"],\n 'type': 'compute.v1.instance',\n 'properties': {\n 'serviceAccounts': [{\n 'email': context.env['project_number'] + '-compute@developer.gserviceaccount.com',\n 'scopes': [...]\n }]\n }\n ...}]\n return {'resources': resources}\n```\n\nWhat's next\n-----------\n\n- Add a template permanently to your project as a [composite type](/deployment-manager/docs/configuration/templates/create-composite-types).\n- [Host templates externally](/deployment-manager/docs/configuration/templates/hosting-templates-externally) to share with others.\n- Add [schemas](/deployment-manager/docs/configuration/templates/using-schemas) to ensure users interact with your templates correctly."]]
