cloudshell gives access to the Google Cloud Shell from the terminal.

Usage

$ cloudshell <command>

Where <command> is one of the following:

info: Display the current status and details of the Cloud Shell environment, including the Docker image and SSH connection information.
ssh: Establish an SSH connection to the Cloud Shell environment. If the environment is not running, it will be started automatically.
start: Start the Cloud Shell environment and wait until it is running.
key <subcommand>: Manage additional public SSH keys for the environment.

Where key <subcommand> is one of the following:

key list: Show all public keys authorized for SSH access.
key add '<key>': Add a new public key. The key should be provided as a string, e.g., "$(cat ~/.ssh/id_rsa.pub)".
key remove '<key>': Remove a previously authorized public key.

Setup

To use cloudshell, you need to configure Google Cloud API access:

Create a project in the Google API Console.
Enable the Cloud Shell API for your project.
Create OAuth 2.0 credentials. Go to the "Credentials" page, click "Create Credentials," and select "OAuth client ID." Choose "Desktop app" as the application type.
Download the credentials as a JSON file and save it as client_secret.json.
Place this file in the application's state directory ($XDG_STATE_HOME/cloudshell/client_secret.json, typically ~/.local/state/cloudshell/client_secret.json)

Authentication

The first time you run any command, cloudshell will initiate an OAuth authentication flow. You will be prompted to open a URL in your browser, grant the application access to your Google account, and paste an authorization code back into the terminal.

Upon successful authentication, an access token is saved to token.json in the state directory. This token will be used for all subsequent API requests.

SSH Key Management

The first time cloudshell is run, it automatically generates a dedicated RSA SSH key pair for connecting to the Cloud Shell environment. This key is stored in the state directory.

When you run cloudshell ssh or cloudshell start, the public key is automatically authorized with the environment.

The key command can still be used to manage additional, user-provided public keys if you have advanced use cases that require them.
