At the beginning of my journey as a network engineer, I was always confused when configuring STP. I often had to double-check and re-read the documentation over and over again. It wasn’t the command syntax that was difficult, commands are easy to rem...
In both personal and professional life, recognizing weaknesses, bouncing back from failures, and staying adaptable are essential for continuous growth. Learning never stops—it’s not a destination but an ongoing process of improvement and self-reflect...
Understanding IGMP and PIM in Multicast Networking In the realm of multicast networking, two essential protocols play distinct but complementary roles: IGMP (Internet Group Management Protocol) and PIM (Protocol Independent Multicast). Understanding ...
Ansible modules allow you to automate various network management tasks, and creating a custom module can significantly boost your automation capabilities. This blog post will guide you through the process of creating a custom Ansible module to intera...
Migrating virtual machines (VMs) across Google Cloud projects can simplify your infrastructure management and resource allocation. In this guide, we'll show you how to create, snapshot, and migrate VMs using Google Cloud's command-line tool gcloud. This will help you move VMs between projects and ensure a smooth transition.
To start, create a new VM instance in your destination project. Here’s how:
gcloud compute instances create rama_test_vm_move \
--image-project rama_lab \
--image machine-images-sf-sa \
--subnet default
In this command:
rama_test_vm_move is the name of the new VM instance.
--image-project specifies the project where the image is located.
--image indicates the name of the image to use.
--subnet assigns the instance to a subnet (in this case, the default subnet).
For consistency, if you need to create another instance with similar parameters, you can use:
gcloud compute instances create ramatestvmmove \
--image-project rama-lab \
--image machine-images-sf-sa \
--subnet default
Source Project:
Create a Snapshot: To snapshot a disk from a VM in your source project, use:
gcloud compute snapshots create sasnapshoot \
--source-disk instance-2 \
--snapshot-type STANDARD \
--source-disk-zone asia-southeast2-a
sasnapshoot is the name of the snapshot.
--source-disk specifies the disk you want to snapshot.
--snapshot-type defines the type of snapshot (STANDARD).
--source-disk-zone is the zone where the source disk is located.
Create an Image from the Snapshot:
After creating the snapshot, convert it into an image:
gcloud compute images create serviceassuranceimages \
--source-snapshot=sasnapshoot
serviceassuranceimages is the name of the new image created from the snapshot.Grant Access to the Image:
Ensure that the new user or project has the necessary permissions to access the image. Assign the user.image role via IAM.
Destination Project:
To create a VM instance in a new project using the image from the source project:
gcloud compute instances create ramatest \
--image-project rama-lab \
--image serviceassuranceimages
In this command:
ramatest is the name of the new VM instance.
--image-project specifies the project where the image is stored.
--image refers to the image created from the snapshot.
Here’s a complete example of migrating a VM from one project to another:
Source Project:
Create Snapshot:
gcloud compute snapshots create exportedsnapshoot \
--source-disk newvmsa-instance \
--snapshot-type STANDARD \
--source-disk-zone asia-southeast2-a
Create Image from Snapshot:
gcloud compute images create exportedserviceassuranceimages \
--source-snapshot=exportedsnapshoot
Destination Project:
Create VM Instance:
gcloud compute instances create serviceassurancevm \
--image-project zeta-crossbar-371709 \
--image exportedserviceassuranceimages
Migrating VMs across Google Cloud projects involves creating snapshots, converting them to images, and deploying new VM instances using these images. By following these steps, you can efficiently manage and transfer your VMs while ensuring they retain their configurations and data. This process is essential for maintaining a flexible and scalable cloud infrastructure, allowing you to optimize resource utilization and project management.
