Vfs

Vfs objects are created by the Vfs class constructor and provide methods for container interaction. All operations on closed Vfs fail.

Creating a Vfs

Create a Vfs by connecting to a running dolang-shell-vfs daemon:

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

Calling a Vfs

Call the Vfs with a block to execute commands inside the container:

a do
  # Commands here run inside the container
  # env and cd also operate in the container context
  run.ls /
  run.cat /etc/os-release

Entering a Vfs context affects all system interactions:

• External programs run inside the container
• sys.env reads and writes the container's environment
• sys.cd changes the container's working directory
• fs operations (open, remove, read, write) access the container's filesystem

Methods

stop()

Signals the VFS daemon to stop accepting new connections and shut down.

a.stop()

See the Container Support guide for setup instructions.

Platform Note: The Vfs class is only available on Unix platforms (Linux, macOS, etc.).
