Deployment Manager | Google Developer Tools

Introduction

Google Cloud Deployment Manager is an infrastructure deployment service that automates the creation and management of Google Cloud resources. With Deployment Manager, you can specify all the resources needed for your application in a declarative format using YAML, Python, or Jinja2 templates. This tutorial will guide you through the process of setting up and using Deployment Manager from start to finish.

Prerequisites

Before you begin, ensure you have the following:

A Google Cloud project with billing enabled.
The Google Cloud SDK installed on your local machine.
Basic knowledge of YAML or Python.

Step 1: Setting Up Your Environment

First, authenticate with your Google Cloud account:

gcloud auth login

Set your desired project:

gcloud config set project [PROJECT_ID]

Enable the Deployment Manager API:

gcloud services enable deploymentmanager.googleapis.com

Step 2: Creating a Deployment Configuration

Create a YAML file named deployment.yaml with the following content:

resources:
- name: my-vm
  type: compute.v1.instance
  properties:
    zone: us-central1-a
    machineType: zones/us-central1-a/machineTypes/f1-micro
    disks:
    - deviceName: boot
      type: PERSISTENT
      boot: true
      autoDelete: true
      initializeParams:
        sourceImage: projects/debian-cloud/global/images/family/debian-9
    networkInterfaces:
    - network: global/networks/default

This configuration defines a single VM instance in the us-central1-a zone.

Step 3: Deploying the Configuration

Deploy the configuration using the following command:

gcloud deployment-manager deployments create my-deployment --config deployment.yaml

After running the command, you should see output indicating the deployment is being created:

The fingerprint of the deployment is 3S2mt7X4z5U=
Waiting for create [operation-1234567890123-abcdef]
............................done.
Create operation operation-1234567890123-abcdef completed successfully.
NAME           TYPE                 STATE      ERRORS
my-vm          compute.v1.instance  COMPLETED  []

Step 4: Updating the Deployment

To update the deployment, modify deployment.yaml and run:

gcloud deployment-manager deployments update my-deployment --config deployment.yaml

For example, to change the machine type, update the machineType property:

machineType: zones/us-central1-a/machineTypes/n1-standard-1

Then run the update command.

Step 5: Deleting the Deployment

To delete the deployment, use the following command:

gcloud deployment-manager deployments delete my-deployment

You will be prompted to confirm the deletion. Type y and press Enter.

Conclusion

In this tutorial, you learned how to set up and use Google Cloud Deployment Manager to automate the deployment of Google Cloud resources. You created a deployment configuration, deployed it, updated it, and finally deleted it. Deployment Manager simplifies the management of your cloud infrastructure, making it easier to maintain consistency and scalability.
