GCP Deployment Manager Demo

Using Deployment Manager and YAML/JINJA templates, this document provides steps to deploy VM instances across different regions along with associated firewall rules and networking resources on GCP. Key steps include creating YAML and JINJA template files defining the infrastructure resources and properties, previewing the deployment, correcting any errors, and running the actual deployment. Templates allow infrastructure to be defined declaratively and deployed consistently rather than manually creating each resource individually on the GCP console.
![Using GCP Deployment Manager to deploy resources
Requirement: Deploy VM instances along with firewall rules, to servers in US and EU using Google Cloud Shell
Environment: GCP Console, GCP Shell, Deployment Manager, YAML and JINJA files
Key results: Login using your GCP subscription, create or reuse earlier VM instances and follow the below
From Shell, create a folder dminfra using mkdir command, change dir to dminfra and open Shell Editor. Using the editor
create 2 new files in the dminfra directory called config.yaml and instance-template.jinja
Copy the file contents as below (see that your Editor does not show YAML syntax errors):
CONFIG.YAML

- path: instance-template.jinja
resources:
# Create the auto-mode network
- name: mynetwork
type: compute.v1.network

- 4. If all is well, you should get the above results, if not there might be issue in syntax or some properties/ resources is missing; use below command to delete any earlier deployment and redeploy. Correct syntax errors in any like TAB SPACES in YAML file gcloud deployment-manager deployments delete dminfra - Please delete earlier failed deployment for new deployment Once errors are gone in PREVIEW, now do actual deployment using update command: gcloud deployment-manager deployments update dminfra
- 5. For your reference below are the screenshots of the two files:
- 7. Hope you will be able to launch various resources using templates, instead of manually creating them from Google Console GUI.
