Intro
Google as most of the cloud providers today, offers a simple Cloud shell solution with all required tools to connect to their platform securely using APIs. However, If you still want to have it in your laptop along with other development tools, you can always install Google Cloud SDK (especially if it’s for educational purpose).
Cloud SDK includes the gcloud, gsutil and bq command-line tool including few components that aren’t installed by default. GCloud is the main command line used to manage cloud resources and enabling services.
Requirement
Whether on windows or Linux, the basic installation and use of Cloud SDK will require 2 elements:
- GCP Free Tier account at least
- Python 3 (3.5 to 3.8) or Python 2 (2.7.9+)
Note: To access the GCP APIs using a specific language (like C++, ruby etc), you can download the Cloud Client Libraries.
I. Cloud SDK Installation
-
Windows
1- Download and execute the following Cloud SDK installer(current version: 355)
2- Follow the on-screen instructions (the installer is also used to upgrade existing installations) .
3- Run the version command to confirm that Cloud SDK was installed correctly.
C:\Users\brokedba gcloud --version Google Cloud SDK 355.0.0 bq 2.0.71 core 2021.08.27 gsutil 4.67
C:\Users\brokedba> where gcloud > C:\Program Files (x86)\Cloud SDK\google-cloud-sdk\bin\gcloud
> C:\Program Files (x86)\Cloud SDK\google-cloud-sdk\bin\gcloud.cmd
Note: The installation can also be done through PowerShell in one liner command (gcloud,bq,gsutil commands can run from either Command Prompt or PowerShell).
PS C:\Users\brokedba> (New-Object Net.WebClient).DownloadFile("https://dl.google.com/dl/cloudsdk/channels/rapid/GoogleCloudSDKInstaller.exe", "$env:Temp\GoogleCloudSDKInstaller.exe")
- Linux
There is either an all-in-one install using packages or using interactive shell script. Let’s start with the script
brokedba~$ curl -sL https://dl.google.com/dl/cloudsdk/channels/rapid/downloads/google-cloud-sdk-355.0.0-linux-x86_64.tar.gz| sudo tar -xz && sudo bash ./google-cloud-sdk/install.sh
# Or more recent approach
$ curl https://sdk.cloud.google.com | bash
-- Workflow
Modify profile to update your $PATH and enable shell command
completion?Do you want to continue (Y/n)? y
The Google Cloud SDK installer will now prompt you to update an rc file to bring the Google Cloud CLIs into your environment.
Enter a path to an rc file to update, or leave blank to use
[/home/brokedba/.bashrc]:brokedba~$ gcloud --version
Google Cloud SDK 355.0.0
bq 2.0.71
core 2021.08.27 gsutil 4.67
► Ubuntu
Option A
We can use apt-get and install it as a package:
1. Add the Cloud SDK distribution URI as a package source
brokedba~$ echo "deb https://packages.cloud.google.com/apt cloud-sdk main" | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list
2. Import the GCP public key
brokedba~$ curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
3. Update and install the Cloud SDK
brokedba~$ curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
Option B
If you are fine with just the core components (gcloud,gsutil,bq, gsutil, kubectl, anthoscli, ..) you can install snap package which also handles the Autoupdate.
brokedba~$ snap install google-cloud-sdk --classic
► REDHAT, Fedora, CENTOS, OLinux
# RHEL/OL/CENTOS (7,8+), Fedora 24+
# – Create a DNF repo with CLoud SDK information
[@localhost]$ sudo tee -a /etc/yum.repos.d/google-cloud-sdk.repo << EOM
name=Google Cloud SDK
baseurl=https://packages.cloud.google.com/yum/repos/cloud-sdk-el8-x86_64

https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
EOM
# Install CLOUD SDK rpm package
[r@localhost]# sudo yum install google-cloud-sdk
II. Initialize gcloud
Once your GCP Free Tier account is created and Cloud SDK installed. All you need is run gcloud init command to:
1- Authorize Cloud SDK to access the GCP platform using your user account
2- Set a new configuration including proper parameters like current project and default GCE region/zone etc..
If you don’t want browser’s auto launch for authorization you can use --console-only or --no-launch-browser
brokedba~$ gcloud init —-skip-diagnostics
Your current configuration has been set to: [default]
You must log in to continue. Would you like to log in (Y/n)?Go to the following link in your browser: https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=……………………………**
Enter verification code:
- The interactive workflow will ask you to hit the displayed link on a browser after entering your user credentials
- When you click allow, a code will be provided which you will past on your terminal to complete the authorization
- Once authenticated, you will be asked to create a project if none exists in your account. project_id is globally unique
Part 2 Enter verification code: 4/1AX4XfWhnJLpVgMtjxxxx.. You are logged in as: [bdba@gmail.com]. This account has no projects. Would you like to create one? (Y/n)? y
Enter a Project ID. Note that a Project ID CANNOT be changed later.Project IDs
must be 6-30 characters in length and start with a lowercase letter. brokedba2000 Waiting for [operations/cp.9218677272527086685] to finish...done.
Your current project has been set to: [brokedba2000].
- If you have an error while creating the project because of error “Callers must accept Terms of Service” make sure you accepted the terms in the console.
- You can now verify your default configuration after the initialization
$ gcloud config list
[compute]
region = us-east1
zone = us-east1-b
[core]
account = bdba@gmail.com
disable_usage_reporting = True
project = brokedba2000
Your active configuration is: [default]

1- “--formats”: Will format gcloud output into Json, yaml, Table,raw value, or cvs including projections.
2- “--filter”: Allows to pick the list of rows to return in the output in combination with formats.
Example > list projects that were created after Jan 1st 2021 and only show 3 specific columns
$ gcloud projects list --format="table(projectNumber,projectId,createTime)" --filter="createTime>2021-01-01"
PROJECT_NUMBER PROJECT_ID CREATE_TIME

gcloud has different versions for its set of commands “alpha” and “beta”. Alpha means that the feature is typically not ready for production and might still be actively developed. Beta on the other hand is normally a completed feature, that is being tested to be production ready.
Examples
There are few requests that you can run to practice with gcloud. Below commands are good examples to start with.
$ gcloud compute regions list --format="table[box](Name,CPUS,status)" --filter="name~us-"
+-----------------------------+
¦ NAME ¦ CPUS ¦ STATUS ¦ ------------------------------- ¦ us-central1 ¦ 0/8 ¦ UP ¦ ¦ us-east1 ¦ 0/8 ¦ UP ¦ ¦ us-east4 ¦ 0/8 ¦ UP ¦ ¦ us-west1 ¦ 0/8 ¦ UP ¦ ¦ us-west2 ¦ 0/8 ¦ UP ¦ ¦ us-west3 ¦ 0/8 ¦ UP ¦
¦ us-west4 ¦ 0/8 ¦ UP ¦ +-----------------------------+
- Create a new project and assign it to the current configuration
$ gcloud projects create My-new-project --name="MY new LAB" --labels=type=lab
$ gcloud config set project My-new-project
-- Check project
$ gcloud compute project-info describe –project My-new-project
- Create and list Current vms in the current project :
$ gcloud compute instances create myvm2 --machine-type=f1-micro --image-family debian-10 --image-project debian-cloud
$ gcloud compute instances list --filter="zone~ us-east1 OR -machineType:f1-micro"
NAME ZONE MACHINE_TYPE PREEMPTIBLE INTERNAL_IP EXTERNAL_IP STATUS
myvm us-east1-b f1-micro 10.142.0.2 34.139.111.13 RUNNING| - Create and list a bucket in google storage :
$ gsutil mb -l us-east1 gs://omarlittle
$ gsutil ls gs://omarlittle/**
..
$ gcloud help compute instances create
NAME
gcloud compute instances create - create Compute Engine virtual machine

…
Enable APIs or install components
- Not all APIs are enabled by default and not all CLOUD SDK components are installed by default . Manual enabling is necessary.
-- APIs
$ gcloud services list available
$ gcloud services enable compute.googleapis.com
-- components
$ gcloud components list
$ gcloud components update
$ gcloud components install COMPONENT_ID
Conclusion:
In this tutorial we learned how to install and configure CLOUD SDK. We also described the command syntax and tried few requests using gcloud and gsutil. Feel free to consult Gcloud Command Reference for more details and examples on gcloud requests.
