We have been using the cloud console to manage the managed instance groups. Let us now learn how to use the command line interface to manage the instance groups. It is important to note that we need to set the project id before we can execute any of these commands mentioned below. Else, you will receive an error. You can use the below command to set the project id.
gcloud config set project <project name>Below are few compute instance commands in gcloud.
gcloud compute instances start <instance 1> <instance 2 > //The instance 1 & 2 are created
gcloud compute instances stop <instance 1> < instance 2 > //The instances 1 & are stopped
gcloud compute instances delete <instance 1> // The instance 1 is deleted
gcloud compute instances delete <instance 1 > --delete-disks=<value> //deletes the boot disk along with instance
gcloud compute instances delete <instance 1> --keep-disks=<value> // keeps the boot disk even if the vm is deleted
gcloud compute instances move <instance 1> --zone us-central1-b --destination-zone us-central-f // moves the instance from central-1b zone to central-f zonet out a
gcloud compute instanceWhen the host system in needs to be updated live migration of the virtual instance happens. The virtual instance is migrated to a different host system from the same zone. The properties of the instance do not change. However, this is not supported for instances with GPU or for Spot instances. The live migration option can be selected when creating the virtual instance under the availability policy.

If you work for a major company, chances are that you will be creating similar type of virtual instance multiple times. It will use the same machine type, has the same start up script, uses the same image family etc… So, it is easy to create an Instance template.

Read Morewhat is a compute Engine? In simple words it is nothing but a virtual machine in google cloud. the service called compute engine in google cloud allows you to create and manage the life cycle of virtual machine instances. You can manage network connectivity and configuration of VM instances. it also allows you to load balance between 2 or more virtual machines.
