This hands-on lab will help to provide experience working with snapshots on Compute Engine, both in the web console and command line format, which we will interact with via Cloud Shell.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Create Snapshot Using Web Console
- Go to the top-left menu > Compute Engine > Snapshots
- Click Create snapshot
- Name snapshot "web-backup-v1"
- In Source Disk dropdown menu, select Website
- Click Create
- Make Instance Change – Update Website to VERSION 2
Connect to the website instance using SSH from the Compute Engine web console
Enter the following command to replace index page with ‘VERSION 2’ instead of ‘VERSION 1’:
sudo sed -i 's/VERSION 1/VERSION 2/' /var/www/html/index.htmlExit SSH session
- Create New Snapshot Using the Cloud Shell
Activate the Cloud Shell by clicking its icon in the top row.
If no ID is displayed in yellow in the Cloud Shell, open the Project panel by clicking the project name in the upper-left.
Copy the current project ID.
In the Cloud Shell, enter the following command:
gcloud config set project <PROJECT_ID>Create a new snapshot with the following command:
gcloud compute disks snapshot website --snapshot-names web-backup-v2 --zone us-central1-aVerify snapshots using web console and Cloud Shell. Notice the size of the second snapshot compared to first:
gcloud compute snapshots listgcloud compute snapshots describe web-backup-v2
- Restore First Snapshot Using Web Console in New Zone
- Go to top left menu > Compute Engine
- Click CREATE INSTANCE
- Name instance "website-restore-1"
- From the Region list, choose us-east1 and from Zone, choose us-east1-a.
- Under Machine configuration, from the Series list, choose First Generation – N1.
- From the Machine type list, choose n1-standard-1.
- Under Boot Disk, click Change.
- In the Boot Disk options, click the Snapshots tab.
- From the Snapshot list, choose web-backup-v1 and click Select.
- In the Firewall section, check the Allow HTTP traffic option.
- Click Create
- Restore Second Snapshot Using Command Line
Navigate to Cloud Shell
Create disk from snapshot:
gcloud compute disks create website-restore-2 --source-snapshot web-backup-v2 --zone us-central1-aCreate new instance from disk:
gcloud compute instances create website-restore-2 --disk name=website-restore-2,boot=yes --zone us-central1-a --tags=http-serverConfirm the new instance by returning to the console VM page and clicking its External IP link.
Congratulations, you’ve completed this hands-on lab!
