Instance Method Details

#create_folder(path, mode) ⇒ void

This method returns an undefined value.

Creates a new directory in the Sandbox at the specified path with the given permissions.

Examples:

# Create a directory with standard permissions
sandbox.fs.create_folder("workspace/data", "755")

# Create a private directory
sandbox.fs.create_folder("workspace/secrets", "700")

Parameters:

  • path (String) —

    Path where the folder should be created. Relative paths are resolved based on the sandbox working directory.

  • mode (String) —

    Folder permissions in octal format (e.g., “755” for rwxr-xr-x).

end

#delete_file(path, recursive: false) ⇒ void

This method returns an undefined value.

Deletes a file from the Sandbox.

Examples:

# Delete a file
sandbox.fs.delete_file("workspace/data/old_file.txt")

# Delete a directory recursively
sandbox.fs.delete_file("workspace/old_dir", recursive: true)

Parameters:

  • path (String) —

    Path to the file to delete. Relative paths are resolved based on the sandbox working directory.

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

    If the file is a directory, this must be true to delete it.

end

#download_file(remote_path, local_path = nil) ⇒ File?

Downloads a file from the Sandbox. Returns the file contents as a string. This method is useful when you want to load the file into memory without saving it to disk. It can only be used for smaller files.

Examples:

# Download and get file content
content = sandbox.fs.download_file("workspace/data/file.txt")
puts content

# Download and save a file locally
sandbox.fs.download_file("workspace/data/file.txt", "local_copy.txt")
size_mb = File.size("local_copy.txt") / 1024.0 / 1024.0
puts "Size of the downloaded file: #{size_mb} MB"

Parameters:

  • remote_path (String) —

    Path to the file in the Sandbox. Relative paths are resolved based on the sandbox working directory.

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

    Optional path to save the file locally. If provided, the file will be saved to disk.

Returns:

  • (File, nil) —

    The file if local_path is nil, otherwise nil

Raises:

  if local_path

    parent_dir = File.dirname(local_path)

#download_file_stream(remote_path, timeout: 30 * 60, on_progress: nil, cancel_event: nil) {|chunk| ... } ⇒ Enumerator?

Downloads a single file from the Sandbox as a stream without buffering the entire file into memory. Yields file content in chunks to the given block, or returns an Enumerator if no block is given.

Examples:

Stream to a local file without loading into memory

File.open("local_copy.bin", "wb") do |f|
  sandbox.fs.download_file_stream("workspace/large-file.bin") { |chunk| f.write(chunk) }
end

Collect chunks with an Enumerator

content = sandbox.fs.download_file_stream("workspace/data.json").reduce(:+)
puts content

Parameters:

  • remote_path (String) —

    Path to the file in the Sandbox. Relative paths are resolved based on the sandbox working directory.

  • timeout (Integer) (defaults to: 30 * 60) —

    Timeout for the download operation in seconds. 0 means no timeout. Default is 30 minutes.

  • on_progress (Proc, nil) (defaults to: nil) —

    Optional callback invoked with a Daytona::DownloadProgress struct containing bytes_received (Integer) and total_bytes (Integer or nil).

  • cancel_event (#set?, nil) (defaults to: nil) —

    Optional cancellation token (anything responding to set?; the standard library’s Concurrent::Event or a small ad-hoc object both work). When set during streaming, the next chunk raises Daytona::Sdk::Error and the underlying HTTP connection is torn down.

Yields:

  • (chunk) —

    Yields each chunk of file content as it arrives

Yield Parameters:

  • chunk (String) —

    A binary string chunk of file content

Returns:

  • (Enumerator, nil) —

    An Enumerator yielding chunks if no block given, nil otherwise

Raises:

  • (Daytona::Sdk::Error) —

    If the file does not exist, the operation fails, or cancel_event is set during streaming

# Upload a local file
sandbox.fs.upload_file("local_file.txt", "tmp/file.txt")

# Upload binary data
data = { key: "value" }.to_json
sandbox.fs.upload_file(data, "tmp/config.json")

Parameters:

  • source (String, IO) —

#upload_file_stream(source, remote_path, timeout: 30 * 60, on_progress: nil, cancel_event: nil) ⇒ void

This method returns an undefined value.

Streams source to the Sandbox without buffering its contents in memory, with optional progress reporting.

Examples:

File.open("large.bin", "rb") do |f|
  sandbox.fs.upload_file_stream(f, "tmp/large.bin",
    on_progress: ->(p) { puts "#{p.bytes_sent} bytes sent" })
end

Parameters:

  • source (String, IO) —

    A local file path or any IO-like object responding to read(n). Strings that don’t reference an existing file are uploaded as their raw bytes (still streamed, just from memory).

  • remote_path (String) —

    Destination path in the Sandbox.

  • timeout (Integer) (defaults to: 30 * 60) —

    Timeout in seconds. 0 means no timeout. Default 30 minutes.

  • on_progress (Proc, nil) (defaults to: nil) —

    Optional callback invoked with a Daytona::UploadProgress struct as libcurl reports bytes actually uploaded.

  • cancel_event (#set?, nil) (defaults to: nil) —

    Optional cancellation token. When set while staging a non-file source or during the libcurl upload, the operation raises Daytona::Sdk::Error and the in-progress upload is aborted (no destination file is left on the sandbox thanks to the daemon’s atomic-rename behaviour).
