The gcloud compute command group lets you create, configure, and manipulate Compute Engine virtual machine (VM) instances.

Ref: https://cloud.google.com/sdk/gcloud/reference/compute

List projects, regions, zones, VMs:

gcloud projects list
gcloud compute zones list
gcloud compute regions list
gcloud compute instances list

Get values:

gcloud config get-value project
gcloud config get-value compute/zone
gcloud config get-value compute/region

Metadata server

Some gcloud compute commands require --project, --region or --zone flags. Instead of specifying these flags each time you run commands, you can set a default region and zone for your project.

The default region and zone in the metadata server apply to all configurations in a project.

Set the default region, zone:

gcloud compute project-info add-metadata --metadata google-compute-default-region= us-central1, google-compute-default-zone= us-central1-b

Then, Initialize the change in your local client:

gcloud init

Unset Metadata server

gcloud compute project-info remove-metadata –keys=google-compute-default-region, google-compute-default-zone

Set/unset the default object:

gcloud config set <object> <object_id>
gcloud config unset <object>

where object:

• project
• compute/region
• compute/zone

Using the Environment variables with set command to set the project, region and zone variables.

set CLOUDSDK_CORE_PROJECT=PROJECT_ID
set CLOUDSDK_COMPUTE_REGION=REGION_ID
set CLOUDSDK_COMPUTE_ZONE=ZONE_ID

and unset:

set CLOUDSDK_CORE_PROJECT=
set CLOUDSDK_COMPUTE_REGION=
set CLOUDSDK_COMPUTE_ZONE=

Working with VMs

Creating VMs:

gcloud compute instances create VM_NAME [--image IMAGE | --image-family IMAGE_FAMILY] --image-project IMAGE_PROJECT

where

• VM_NAME: the name of the new VM
• IMAGE or IMAGE_FAMILY: Refer https://cloud.google.com/compute/docs/images/os-details#general-info
• IMAGE_PROJECT: the project containing the image.

More options: https://cloud.google.com/compute/docs/instances/create-start-instance

Example:
Create a VM with overwriting the default vars:

• named catdcwebt1,
• zone us-central1-b,
• OS windows-server-2019-dc-v20210413,
• 4 vCPU,
• 16384 = 16 Gb of RAM,
• 150Gb of SSD
• Allow http, https

gcloud compute --project=nrd-test-311308 instances create catdcwebt1 --zone=us-central1-b --machine-type=n2-custom-4-16384 --subnet=default --tags=http-server,https-server --image=windows-server-2019-dc-v20210413 --image-project=windows-cloud --boot-disk-size=150GB --boot-disk-type=pd-ssd --boot-disk-device-name= catdcwebt1

Starting, Stopping VMs:

gcloud compute instances start|stop VM_NAME

Resetting Windows Password Logon:

gcloud compute --project PROJECT_ID reset-windows-password VM_NAME --zone ZONE_ID

Example:

gcloud compute --project "nrd-test-311308" reset-windows-password "catdcwebt1" --zone "us-central1-b"

Connecting to VMs:

Using SSH to connect to instances:

gcloud compute ssh VM_NAME

Example:

gcloud compute ssh --zone "us-central1-b" "catdcwebt1" --tunnel-through-iap --project "tdc-test-311308"

Port forwarding over SSH

gcloud compute ssh catdcwebt1 --project tdc-test-311308 --zone us-central1-b -- [-L 2222:localhost:8888]

where:

• 2222 is the local port you’re listening on.
• 8888 is the remote port you’re connecting to.

IAP for TCP forwarding:

Starts a tunnel to Cloud IAP (Identity-Aware Proxy) for TCP forwarding RDP port 3389 on the VM and turned it to the localhost with port 1975:

gcloud compute start-iap-tunnel  catdcwebt1 3389 --local-host-port=localhost:1975

Transfer files

To transfer files using SCP, create a firewall rule that allows SSH connections on port 22.

Copy files to a VM:

gcloud compute scp LOCAL_FILE_PATH VM_NAME:REMOTE_DIRECTORY

Download files from a VM:

gcloud compute scp VM_NAME:REMOTE_DIRECTORY LOCAL_FILE_PATH
