container

The container module provides container support on Linux. It allows running commands inside containers from Do scripts on the host.

Functions

host func ...args

Executes a callable in a fresh host context, regardless of the current context. This provides a way to escape from agent contexts back to the host environment for specific operations.

Name	Type	Description
func	func	Block to execute in fresh host context
args		Additional arguments to pass to func

Returns: Return value of the executed callable

Note that environment variables and working directory are reset to the current process-level values. For dolang-shell these will be the original values at process start time.

Example:

# Execute in fresh host context
host do
  program.echo "Running with original host environment: $(cd())"

Types

Vfs

The Vfs class connects to a running dolang-shell-vfs daemon via its Unix socket. Use the unix_socket key argument to specify the socket path.

Constructor: Vfs unix_socket: path

Name	Type	Description
unix_socket	str	Path to the agent's Unix socket

Returns: Vfs object

let a = Vfs unix_socket: /tmp/agent/socket

See the Vfs documentation for details on using Vfs objects.

Platform Note: The Vfs class is only available on Unix platforms (Linux, macOS, etc.). On Windows, the Vfs class is not available.
