Cloud Deployment Manager will reach end of support onDecember 31, 2025. If you currently use Deployment Manager, please migrate to Infrastructure Manager or an alternative deployment technology by December 31, 2025 to ensure your services continue without interruption.
Stay organized with collectionsSave and categorize content based on your preferences.
In this step, you will explore a template that imports other templates.
After incorporating these templates, your configuration only needs to call a
single template to create a deployment with all of these resources.
Opening the template for a network
Open the template namedcompute-engine-template.py:
cddeploymentmanager-samples/examples/v2/step_by_step_guide/step6_use_multiple_templates/python
nanocompute-engine-template.py# use your preferred text editor
This template imports other templates, for all the resources in the deployment:vm-template.py,vm-template-2.pyfor virtual machines (VMs),network-template.pyfor a network, andfirewall-template.pyfor a firewall
rule.

Viewing the configuration
Open the configuration file for the deployment:
cddeploymentmanager-samples/examples/v2/step_by_step_guide/step6_use_multiple_templates/python
nanoconfig-with-many-templates.yaml# use your preferred text editor
Notice that the configuration did not directly call the other templates.
However, the other templates are imported becausecompute-engine-template.pydepends on the other templates.

Looking ahead: template properties and environment variables
Next, you will replace some hard-coded parts of templates with reusable
patterns such as custom template and environment variables.
Deleting your deployment
We recommend that you delete the deployment to avoid charges. You
don't need this deployment for the next step. Run the following command to
delete the deployment:
