Constructor Details

#initialize(sandbox_dto:, config:, sandbox_api:, subscription_manager:, otel_state: nil, analytics_api_url_provider: nil) ⇒ Sandbox

Internal — obtain sandboxes via Daytona::Daytona#create, Daytona::Daytona#get, or Daytona::Daytona#list rather than constructing directly.

Instance Method Details

#archive ⇒ void

This method returns an undefined value.

Archives the sandbox, making it inactive and preserving its state. When sandboxes are archived, the entire filesystem state is moved to cost-effective object storage, making it possible to keep sandboxes available for an extended period. The tradeoff between archived and stopped states is that starting an archived sandbox takes more time, depending on its size. Sandbox must be stopped before archiving.

#create_lsp_server(language_id:, path_to_project:) ⇒ Daytona::LspServer

Creates a new Language Server Protocol (LSP) server instance. The LSP server provides language-specific features like code completion, diagnostics, and more.

Parameters:

  • language_id (Symbol) —

    The language server type (e.g., Daytona::LspServer::Language::PYTHON)

  • path_to_project (String) —

    Path to the project root directory. Relative paths are resolved based on the sandbox working directory.

Returns:

def create_lsp_server(language_id:, path_to_project:)

end

#create_signed_preview_url(port, expires_in_seconds = nil) ⇒ DaytonaApiClient::SignedPortPreviewUrl

Creates a signed preview URL for the sandbox at the specified port.

Examples:

signed_url = sandbox.create_signed_preview_url(3000, 120)
puts "Signed URL: #{signed_url.url}"
puts "Token: #{signed_url.token}"

Parameters:

  • port (Integer) —

    The port to open the preview link on

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

    The number of seconds the signed preview URL will be valid for. Defaults to 60 seconds.

Returns:

  • (DaytonaApiClient::SignedPortPreviewUrl) —

    The signed preview URL response object

end

#create_ssh_access(expires_in_minutes) ⇒ DaytonaApiClient::SshAccessDto

Creates an SSH access token for the sandbox.

Parameters:

  • expires_in_minutes (Integer) —

    TThe number of minutes the SSH access token will be valid for

Returns:

  • (DaytonaApiClient::SshAccessDto)

def create_ssh_access(expires_in_minutes)

end

#delete(timeout = DEFAULT_TIMEOUT, wait: false) ⇒ void

This method returns an undefined value.

Deletes the Sandbox.

By default returns as soon as the deletion request is accepted (matching origin/main behavior). Pass wait: true to block until the Sandbox reaches the destroyed state.

Parameters:

  • timeout (Numeric) (defaults to: DEFAULT_TIMEOUT) —

    Maximum wait time in seconds (defaults to 60 s). Only meaningful when wait is true.

  • wait (Boolean) (defaults to: false) —

    When true, block until the Sandbox is destroyed.

#download_url(path, ttl_seconds: nil) ⇒ String

Creates a pre-signed URL for downloading a file from the Sandbox.

The URL works with any HTTP client without auth headers and stays valid across sandbox restarts (downloads succeed only while the sandbox is running). The signing key is cached locally for up to 15 seconds; if the key was rotated from another client, URLs may be rejected until the cache refreshes.

Examples:

url = sandbox.download_url('/home/user/report.pdf')
# curl "$url" -o report.pdf

Parameters:

  • path (String) —

    Path to the file in the Sandbox.

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

    How long the URL stays valid, in seconds. Defaults to 3600. Zero or negative means the URL never expires.

Returns:

  • (String) —

    Pre-signed download URL.

#preview_url(port) ⇒ DaytonaApiClient::PortPreviewUrl

#refresh_activity ⇒ void

This method returns an undefined value.

Refreshes the sandbox activity to reset the timer for automated lifecycle management actions.

This method updates the sandbox's last activity timestamp without changing its state. It is useful for keeping long-running sessions alive while there is still user activity.

#resize(resources, timeout = DEFAULT_TIMEOUT) ⇒ void

This method returns an undefined value.

Resizes the Sandbox resources.

Changes the CPU, memory, or disk allocation. Resizing a started sandbox accepts only CPU and memory increases. Disk resize requires a stopped sandbox; disk can only grow. GPU is not resizable — to change GPU, create a new sandbox.

Examples:

Resize a started sandbox (CPU and memory can be increased)

sandbox.resize(Daytona::Resources.new(cpu: 4, memory: 8))

Resize a stopped sandbox (CPU, memory, and disk can be changed)

sandbox.stop
sandbox.resize(Daytona::Resources.new(cpu: 2, memory: 4, disk: 30))

Parameters:

  • resources (Daytona::Resources) —

    New resource configuration (cpu, memory, disk only)

  • timeout (Numeric) (defaults to: DEFAULT_TIMEOUT) —

    Maximum wait time in seconds (defaults to 60 s)

Raises:

  • (Sdk::Error) —

    If resources.gpu or resources.gpu_type is set

#ttl_minutes=(minutes) ⇒ void

This method returns an undefined value.

#update_secrets(secrets) ⇒ void

This method returns an undefined value.

Replaces the set of organization vault secrets mounted in the Sandbox. Pass an empty hash to detach all secrets.

Parameters:

  • secrets (Hash<String, String>) —

    Mapping of environment variable name to organization vault secret name

#upload_url(path, ttl_seconds: nil) ⇒ String

Creates a pre-signed URL for uploading a file to the Sandbox.

Send a POST request with the file as multipart/form-data. The URL works with any HTTP client without auth headers. The signing key is cached locally for up to 15 seconds; if the key was rotated from another client, URLs may be rejected until the cache refreshes.

Examples:

url = sandbox.upload_url('/home/user/data.bin')
# curl -X POST -F "file=@local.bin" "$url"

Parameters:

  • path (String) —

    Destination path for the uploaded file in the Sandbox.

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

    How long the URL stays valid, in seconds. Defaults to 3600. Zero or negative means the URL never expires.
