Installing and initializing gcloud in GCP - Step-by-Step CLI Walkthrough

Introduction

To work with Google Cloud services from your computer, you need a tool called gcloud. Installing and setting it up lets you control your cloud projects easily from the command line.

When you want to create or manage Google Cloud resources from your laptop or server.

When you need to deploy applications to Google Cloud.

When you want to check the status of your cloud services quickly.

When you want to switch between different Google Cloud projects.

When you want to run scripts that automate cloud tasks.

Commands

This command downloads and runs the Google Cloud SDK installer script to install the gcloud tool on your system.

Terminal

curl https://sdk.cloud.google.com | bash

Expected Output

Welcome to the Google Cloud SDK!



This script will install all the gcloud command line tools.



You will be prompted to update your PATH and enable command completion.



Starting installation...



Installation complete.

This command restarts your shell so that the changes to your PATH take effect and you can use gcloud immediately.

Terminal

exec -l $SHELL

Expected Output

No output (command runs silently)

This command starts the setup process to log in to your Google account and select a default project to work with.

Terminal

gcloud init

Expected Output

Welcome! This command will take you through the configuration of gcloud.



Pick configuration to use:

 [1] Re-initialize this configuration

 [2] Create a new configuration



Enter your numeric choice: 1



You are logged in as: [e-mail]



Pick cloud project to use:

 [1] my-first-project

 [2] my-second-project



Enter your numeric choice: 1



Your gcloud CLI is now configured.

This command shows the current settings of gcloud, including which project and account are active.

Terminal

gcloud config list

Expected Output

[core]

account = [e-mail]

project = my-first-project

Key Concept

If you remember nothing else, remember: installing gcloud and running 'gcloud init' sets up your access to Google Cloud from your computer.

Common Mistakes

Not restarting the shell after installation

The system does not recognize the gcloud command because the PATH was not updated in the current session.

Run 'exec -l $SHELL' or close and reopen your terminal to refresh the PATH.

Skipping 'gcloud init' after installation

Without initialization, gcloud has no account or project set, so commands will fail or ask for configuration every time.

Always run 'gcloud init' to log in and select your default project.

Summary

Install gcloud SDK by downloading and running the installer script.

Restart your shell to update the PATH and enable gcloud commands.

Run 'gcloud init' to log in and select your Google Cloud project.

Use 'gcloud config list' to verify your current configuration.

Practice

1. What is the main purpose of installing the gcloud command-line tool on your computer?

easy

A. To replace the Google Cloud Console website

B. To create virtual machines automatically

C. To manage Google Cloud resources directly from your computer

D. To install operating systems on cloud servers

Solution

1. Step 1: Understand what gcloud does

   The gcloud tool is designed to let users control Google Cloud services from their local machine.

2. Step 2: Compare options to the main purpose

   Only To manage Google Cloud resources directly from your computer correctly states that gcloud manages cloud resources from your computer, while others describe unrelated tasks.

3. Final Answer:

   To manage Google Cloud resources directly from your computer -> Option C

4. Quick Check:

   Installing gcloud = Manage cloud from PC [OK]

Hint: Think: local tool to control cloud resources [OK]

Common Mistakes:

• Confusing gcloud with cloud VM creation
• Thinking it replaces the web console
• Assuming it installs OS on servers

2. Which command correctly initializes the gcloud tool after installation?

easy

A. gcloud init

B. gcloud configure

C. gcloud start

D. gcloud setup

Solution

1. Step 1: Recall the initialization command

   The official command to start setup and login for gcloud is gcloud init.

2. Step 2: Verify other options

   Commands like gcloud start, gcloud configure, and gcloud setup do not exist or are incorrect for initialization.

3. Final Answer:

   gcloud init -> Option A

4. Quick Check:

   Initialize gcloud = gcloud init [OK]

Hint: Remember: init means initialize [OK]

Common Mistakes:

• Typing gcloud start instead of gcloud init
• Using non-existent commands like gcloud setup
• Confusing with other CLI tools

3. After running gcloud init, which of the following happens?

medium

A. You are prompted to log in to your Google account

B. Your cloud project is automatically deleted

C. The tool installs a new operating system

D. Your local files are uploaded to the cloud

Solution

1. Step 1: Understand the purpose of gcloud init

   This command helps you log in and select your Google Cloud project.

2. Step 2: Evaluate the options

   Only You are prompted to log in to your Google account correctly describes the login prompt. Other options describe unrelated or harmful actions.

3. Final Answer:

   You are prompted to log in to your Google account -> Option A

4. Quick Check:

   gcloud init = login prompt [OK]

Hint: Init means login and setup project [OK]

Common Mistakes:

• Thinking it deletes projects
• Assuming it installs OS
• Believing it uploads local files automatically

4. You ran gcloud init but got an error saying 'command not found'. What is the most likely cause?

medium

A. You typed the command correctly but your internet is down

B. You did not install the gcloud tool before running the command

C. Your Google Cloud project is inactive

D. You need to restart your computer after running gcloud init

Solution

1. Step 1: Analyze the error message

   'command not found' means the system does not recognize the command, usually because the tool is not installed or not in the system path.

2. Step 2: Check other options

   Internet issues or project status do not cause this error. Restarting computer is not required before installation.

3. Final Answer:

   You did not install the gcloud tool before running the command -> Option B

4. Quick Check:

   'command not found' = tool missing [OK]

Hint: Error means tool not installed or path missing [OK]

Common Mistakes:

• Blaming internet for 'command not found'
• Thinking project status affects command recognition
• Restarting computer unnecessarily

5. You want to set up gcloud for a new project and ensure you can switch projects easily later. Which sequence of commands should you run after installing gcloud?

hard

A. Run gcloud login to log in, then gcloud project select [PROJECT_ID] to choose a project

B. Run gcloud configure to set up, then gcloud project change [PROJECT_ID] to switch projects

C. Run gcloud start to initialize, then gcloud switch project [PROJECT_ID] to change projects

D. Run gcloud init to log in and select a project, then use gcloud config set project [PROJECT_ID] to switch projects

Solution

1. Step 1: Identify correct initialization command

   The correct command to start setup is gcloud init, which logs you in and lets you pick a project.

2. Step 2: Identify how to switch projects

   To switch projects later, the command is gcloud config set project [PROJECT_ID]. Other commands listed do not exist or are incorrect.

3. Final Answer:

   Run gcloud init to log in and select a project, then use gcloud config set project [PROJECT_ID] to switch projects -> Option D

4. Quick Check:

   Init + config set project = setup and switch [OK]

Hint: Use gcloud init then gcloud config set project [OK]

Common Mistakes:

• Using non-existent commands like gcloud login
• Trying commands like gcloud start or gcloud switch project
• Confusing project switching commands
