end

#create_pty_session(id:, cwd: nil, envs: nil, pty_size: nil) ⇒ PtyHandle

Creates a new PTY (pseudo-terminal) session in the Sandbox.

Creates an interactive terminal session that can execute commands and handle user input. The PTY session behaves like a real terminal, supporting features like command history.

Examples:

# Create a basic PTY session
pty_handle = sandbox.process.create_pty_session(id: "my-pty")

# Create a PTY session with specific size and environment
pty_size = Daytona::PtySize.new(rows: 30, cols: 120)
pty_handle = sandbox.process.create_pty_session(
  id: "my-pty",
  cwd: "/workspace",
  envs: {"NODE_ENV" => "development"},
  pty_size: pty_size
)

# Use the PTY session
pty_handle.wait_for_connection
pty_handle.send_input("ls -la\n")
result = pty_handle.wait
pty_handle.disconnect

Parameters:

  • id (String) —

    Unique identifier for the PTY session. Must be unique within the Sandbox.

  • cwd (String, nil) (defaults to: nil) —

    Working directory for the PTY session. Defaults to the sandbox’s working directory.

  • envs (Hash<String, String>, nil) (defaults to: nil) —

    Environment variables to set in the PTY session. These will be merged with the Sandbox’s default environment variables.

  • pty_size (PtySize, nil) (defaults to: nil) —

    Terminal size configuration. Defaults to 80x24 if not specified.

Returns:

  • (PtyHandle) —

    Handle for managing the created PTY session. Use this to send input, receive output, resize the terminal, and manage the session lifecycle.

Raises:

  • (Daytona::Sdk::Error) —

    If the PTY session creation fails or the session ID is already in use.

#create_session(session_id) ⇒ void

This method returns an undefined value.

Creates a new long-running background session in the Sandbox

Sessions are background processes that maintain state between commands, making them ideal for scenarios requiring multiple related commands or persistent environment setup.

Examples:

# Create a new session
session_id = "my-session"
sandbox.process.create_session(session_id)
session = sandbox.process.get_session(session_id)
# Do work...
sandbox.process.delete_session(session_id)

Parameters:

  • session_id (String) —

    Unique identifier for the new session

def delete_pty_session(session_id)
  toolbox_api.delete_pty_session(session_id)
end

#delete_session(session_id) ⇒ Object

Terminates and removes a session from the Sandbox, cleaning up any resources associated with it

Examples:

# Create and use a session

# ... use the session ...

# Clean up when done
sandbox.process.delete_session("temp-session")

Parameters:

  • session_id (String) —

    Unique identifier of the session to delete

# File 'lib/daytona/process.rb', line 382

def delete_session(session_id) = toolbox_api.delete_session(session_id)

#exec(command:, cwd: nil, env: nil, timeout: nil) ⇒ ExecuteResponse

Execute a shell command in the Sandbox

Examples:

# Simple command
response = sandbox.process.exec("echo 'Hello'")
puts response.artifacts.stdout
=> "Hello\n"

# Command with working directory
result = sandbox.process.exec("ls", cwd: "workspace/src")

# Command with timeout
result = sandbox.process.exec("sleep 10", timeout: 5)

Parameters:

  • command (String) —

    Shell command to execute

  • cwd (String, nil) (defaults to: nil) —

    Working directory for command execution. If not specified, uses the sandbox working directory

  • env (Hash<String, String>, nil) (defaults to: nil) —

    Environment variables to set for the command

  • timeout (Integer, nil) (defaults to: nil) —

    Maximum time in seconds to wait for the command to complete.
