Cloud Shell😶‍🌫️

Hi Ninjas!🥷 We are going to understand a critical topic, Cloud Shell. It is an interactive Google Cloud shell environment that enables you to explore Google Cloud, learn about it, and manage your resources and projects from a web browser.

Cloud Shell

For users with a Google Cloud account, Cloud Shell is free. While Google Cloud Console is a temporary virtual machine, Cloud Shell is a locally installed tool.

Use Cloud Shell💡

In this section, we'll go over how to launch and configure a new Cloud Shell session.

Start a new session

On the Google Cloud console's top menu, select Activate Cloud Shell 

A command-line prompt is shown when a Cloud Shell session launches in a new frame at the bottom of the console. The initialization of the session may take a few seconds.

Use the terminal

A terminal window opens in the console and offers command-line access to the virtual machine instance through Cloud Shell.

You can use the cloud shell command to start tutorials, open the Cloud Shell Editor, and download files, and use it to access the Google Cloud CLI and other command-line tools.

Use the Cloud Shell Editor

The convenience of  editing and viewing files in the exact location where projects are developed and deployed is made possible by the built-in code editor. By selecting Open Editor from the toolbar of the Cloud Shell window, the Cloud Shell Editor is opened.

Choose ephemeral mode

On your temporarily assigned virtual machine, Cloud Shell preloads 5 GB of free persistent disc storage by default. Your $HOME directory is shown here. The files in your home directory remain accessible between sessions when you use the standard Cloud Shell experience.

Use Cloud Shell in ephemeral mode if persistent storage is not a requirement. Ephemeral mode requires less setup and has no disc attachment or archive, so you can use Cloud Shell more quickly. However, this implies that all files you produce while using ephemeral mode are deleted along with the virtual machine when the session expires.

Add ephemeral=true to the URL to select ephemeral mode, or open the Cloud Shell More menu, select Ephemeral mode, and click Save.

Always start Cloud Shell in ephemeral mode before clicking Save to make ephemeral mode your default for Cloud Shell.

Resize the browser window.

To change the display window:

  1. To hide or restore the session display, click Hide Shell Button Hide or Restore Shell Button Restore.
  2. To open the session in a new window, click Detach Shell Button Open Session in New Window.
  3. At the top of the console window to close the detached window and restart the console session Activate Cloud Shell.
  4. Select Settings Button Settings, then select either Switch to Light Theme or Switch to Dark Theme.

Launch the Cloud Shell Editor💯

To best suit your use case, the Cloud Shell Editor can be launched in a variety of ways.

Launch a standalone Cloud Shell Editor session

Directly launching a Cloud Shell Editor session with ide.cloud.google.com is the simplest way to start a Cloud Shell session and start using Cloud Shell Editor. There is still access to

Activate cloud shell

By selecting Open terminal from the Cloud Shell menu bar, you can access the Cloud Shell terminal anytime.

Use shell.cloud.google.com instead to start a standalone Cloud Shell session with the Cloud Shell Editor and Terminal already running.

Launch Cloud Shell Editor from the console

To launch a Cloud Shell session from the console, click Activate Cloud Shell in your console. This launches a session in the bottom pane of your console.

To launch the editor, click  Code Editor Button  Open Editor on the toolbar of the Cloud Shell window.

Launch from the Cloud Shell terminal

From the Cloud Shell terminal (accessible by clicking Activate Cloud Shell in your console), you can run the following command:

Cloud shell edit.

This launches the Cloud Shell Editor in the same pane.

Cloud Shell Editor interface🖥️

The features of the Cloud Shell Editor.

Viewing and editing files

With continued access to Cloud Shell, the built-in code editor in Cloud Shell enables you to browse file directories and edit and view files. Every Cloud Shell instance includes the Theia-based Cloud Shell Editor by default.

To work with the Cloud Shell Editor, follow these steps:

 

  1. By selecting Open Editor from the toolbar of the Cloud Shell window, the Cloud Shell Editor is opened. Above the Cloud Shell terminal window, the editor appears.Recommendation: Go to ide.cloud.google.com to start the Cloud Shell Editor.
  2. Browse through the file directories using the left-hand pane. You can view and edit your files using the right-hand pane.
  3. The Cloud Shell toolbar in the top right corner provides access to features such as switching between the editor and the Cloud Shell window, uploading and downloading files, previewing web applications on a Cloud Shell virtual machine instance, and viewing usage statistics.
Cloud Shell and Editor session

Alternately, you can run the cloud shell command in your console to open an existing file—for instance, README-cloudshell.txt from the environment above—in the Cloud Shell Editor. As an illustration, use

cloudshell edit README-cloudshell.txt

Uploading and downloading files

The Cloud Shell Editor's Explorer allows you to manage your files further. To upload or download files, use the menu by right-clicking the directory or file you want to use in the Cloud Shell Editor Explorer: Copy the download link, download the files, then upload them.

Right-click a file or folder within the Explorer to bring up menu to access Upload/Download options

Alternatively, you can navigate to FileDownload/Upload Files.

Activity bar

You can access the views offered in the Cloud Shell Editor through the Activity bar, which is located on the left side of the Editor.

These are the Activity bar views:

  • Explorer icon ExplorerCheck out the files and folders in your active workspace.
  • Search icon SearchLook up a string or regular expression in your files.
  • Debug View icon Source ControlUtilize the Git support of the Cloud Shell Editor to control application files.
  • Debug View icon DebugSet breakpoints, look at variables, and debug your program.
  • Cloud APIs Cloud Code - Cloud APIsExplore, enable, and incorporate Cloud Client Libraries into your project
  • Cloud Run icon Cloud Code - Cloud RunKeep an eye on and control your Cloud Run resources.
  • Kubernetes icon Cloud Code - KubernetesKeep an eye on and control your Kubernetes resources.
     

Configure Cloud Shell🎯

The configuration options for Cloud Shell are covered in this section so you can personalize your usage.

Configuration files in your Cloud Shell home directory

5 GB of free persistent disc space are made available by Cloud Shell and mounted as your $HOME directory. Scripts, user configuration files like.bashrc and.vimrc, and any other files you keep in your home directory are persistent across sessions. It's a great way to personalise Cloud Shell's behavior because your.bashrc persists across sessions. Similarly, you can install packages into your home directory to make them persistent.

Pre-configured environment variables

The active project in Cloud Shell is immediately propagated to your gcloud configuration inside of Cloud Shell upon startup. The project ID is defined by the environmental variable GOOGLE_CLOUD_PROJECT, which is also set to point to the active project in Cloud Shell and is used by Application Default Credentials library support.

The environment variable CLOUD SHELL has the value actual. Applications can check this variable to see if they are using Cloud Shell.

Disable or reset Cloud Shell🧑‍💻

Cloud Shell is a feature that managed user accounts can disable. You can cleanly restore your Cloud Shell home directory.

Disable Cloud Shell for managed user accounts

Cloud Shell can be turned off for G Suite and Cloud Identity managed user accounts. To do this, open the Google Admin console, go to Apps > Additional Google services > Google Cloud Platform > Cloud Shell Settings, and then disable "Cloud Shell Access Settings."

You must use access groups, add the specific users to the group, and deactivate the group's Cloud Shell access setting to disable Cloud Shell for particular users. See the Controlling who uses Google Cloud in your organisation guide for complete instructions.

Reset Cloud Shell

Note: Before resetting your Cloud Shell home directory, think about logging in as root in Safe mode and fixing any file-related problems. All files in your home directory will be permanently deleted if you do this.

To cleanly restore your Cloud Shell home directory:

  • Check the home directory for any personal files: 
 ls -a $HOME              

 

  • Clear out your home directory of all files:
  sudo rm -rf $HOME

 

  • Click more vert MoreRestart Cloud Shell menu. Start Cloud Shell again. 

    The confirmation dialogue will appear. Click Restart Cloud Shell.

    The home directory is provisioned for a new VM and reset to its initial state.
