A Beginner’s Guide to Cloud Shell Commands and gcloud: GSP002 2024

Cloud Shell Commands and gcloud: GSP002 Cloud Shell provides command-line access to Google Cloud resources. Running on a Debian-based virtual machine with a 5-GB home directory, it comes pre-installed with the gcloud tool and other utilities, allowing you to start working quickly.

Cloud Shell Commands and gcloud: GSP002 Objectives :

Practice using gcloud commands.
Connect to compute services hosted on Google Cloud.

Cloud Shell Commands and gcloud: GSP002 Prerequisites:

A Google Cloud account.
Google Cloud SDK installed on your local machine.
Basic knowledge of command-line operations.

ALSO READ:

Action Plan :

Step 1: Sign in to Google Cloud Platform

Go to the Google Cloud Platform Console.
Sign in with your Google account credentials.

Step 2: Activate Cloud Shell

Open Cloud Shell by clicking the terminal icon in the top-right corner of the console.

List the active account name (optional):

gcloud auth list

Click on Authorize.

To list the project ID:

gcloud config list project

Step 3: Configuring Your Environment

Set Region:

gcloud config set compute/region REGION

Set Zone:

gcloud config set compute/zone ZONE

View the project ID:

gcloud config get-value project

To view details about the project:

gcloud compute project-info describe --project $(gcloud config get-value project)

Set Environment Variables:

Create an environment variable to store your Project ID:

export PROJECT_ID=$(gcloud config get-value project)

Create an environment variable to store your Zone:

export ZONE=$(gcloud config get-value compute/zone)

To verify the variables:

echo -e "PROJECT ID: $PROJECT_ID\nZONE: $ZONE"

Step 4: Create a Virtual Machine

To create your Virtual Machine:

gcloud compute instances create gcelab2 --machine-type e2-medium --zone $ZONE

Step 5: Filtering Command-Line Output

List the compute instances available in the project:

gcloud compute instances list

List the gcelab2 virtual machine:

gcloud compute instances list --filter="name=('gcelab2')"

List the firewall rules for the default network:

gcloud compute firewall-rules list --filter="network='default'"

Step 6: Connecting to Your Virtual Machine

Connect to your virtual machine with SSH:

gcloud compute ssh gcelab2 --zone $ZONE

To continue, type Y.

Install Nginx Web Server:

sudo apt install -y nginx

Exit the SSH session:

exit

Step 7: Update Firewall Rule

Create a firewall rule to allow HTTP traffic:

gcloud compute firewall-rules create default-allow-http --direction=INGRESS --priority=1000 --network=default --action=ALLOW --rules=tcp:80 --source-ranges=0.0.0.0/0 --target-tags=http-server

List the firewall rules for the project:

gcloud compute firewall-rules list --filter=ALLOW:'80'

Step 8: Viewing the System Logs

List available logs:

gcloud logging logs list

List related compute resources:

gcloud logging logs list --filter="compute"

Testing Your Understanding

Three basic ways to interact with Google Cloud services and resources are:

Client libraries
Command-line interface
Cloud Console
