Google Cloud Deployment Manager Tutorial

Introduction

Google Cloud Deployment Manager is an infrastructure management service that automates the creation and management of Google Cloud resources. It allows you to specify all the resources needed for your application in a declarative format using YAML, Python, or Jinja2 templates, and then deploy them in a single operation.

Prerequisites

Before you begin, ensure you have the following:

• A Google Cloud Platform (GCP) account.
• The Google Cloud SDK installed on your local machine.
• Basic knowledge of GCP services and YAML syntax.

Setting Up Deployment Manager

To start using Deployment Manager, follow these steps:

1. Open the Google Cloud Console and create a new project or select an existing one.
2. Enable the Deployment Manager API:
gcloud services enable deploymentmanager.googleapis.com
3. Authenticate your gcloud session:
gcloud auth login
4. Set your project:
gcloud config set project [YOUR_PROJECT_ID]

Creating a Basic Configuration

Let's create a simple configuration file to deploy a Google Cloud Storage bucket.

1. Create a new directory for your configuration files:
mkdir deployment-manager-tutorial
cd deployment-manager-tutorial
2. Create a file named storage-bucket.yaml with the following content:
nano storage-bucket.yaml

resources:
- name: my-storage-bucket
  type: storage.v1.bucket
  properties:
    location: US
                        

Deploying the Configuration

To deploy the configuration, use the following command:

This command creates a deployment named my-deployment using the configuration specified in storage-bucket.yaml.

Updating the Deployment

If you need to update the deployment, modify the configuration file and then use the following command:

For example, to change the bucket's location to Europe, update storage-bucket.yaml:

resources:
- name: my-storage-bucket
  type: storage.v1.bucket
  properties:
    location: EU
                    

Then run the update command.

Deleting the Deployment

To delete the deployment, use the following command:

This command deletes all resources associated with the deployment.

Advanced Configurations

Deployment Manager supports more advanced configurations using templates and multiple resources. For example, you can create a network and a VM instance in the same deployment. Here is an example configuration file:

resources:
- name: my-network
  type: compute.v1.network
  properties:
    autoCreateSubnetworks: false

- name: my-subnetwork
  type: compute.v1.subnetwork
  properties:
    ipCidrRange: 10.0.0.0/24
    region: us-central1
    network: $(ref.my-network.selfLink)

- name: my-vm
  type: compute.v1.instance
  properties:
    zone: us-central1-a
    machineType: zones/us-central1-a/machineTypes/n1-standard-1
    disks:
    - deviceName: boot
      type: PERSISTENT
      boot: true
      autoDelete: true
      initializeParams:
        sourceImage: projects/debian-cloud/global/images/family/debian-9
    networkInterfaces:
    - network: $(ref.my-network.selfLink)
      subnetwork: $(ref.my-subnetwork.selfLink)
                    

Conclusion

In this tutorial, you learned how to use Google Cloud Deployment Manager to create, update, and delete resource deployments. Deployment Manager simplifies and automates the management of your Google Cloud resources using a declarative approach.
