hrun

hrun

Run commands on your host machine from inside your distrobox or toolbx container.

Highly inspired by host-spawn.

[!WARNING]
This is a work in progress and not yet ready for production use. Expect breaking changes and the worst possible bugs. A LOT of features are missing, the code is not optimized, security is not a concern and the documentation is incomplete. Good luck!

Usage

First you have to start the socket server on your host machine:

Usage: hrun [options] [command] [args...]

Options:
  -h, --help         Display this help message.
  --start            Start the server.
  --allowed-cmd      Specify allowed command (can be used multiple times).
  --socket           Specify an alternative socket path (default: /tmp/hrun.sock).

If command is "start", it starts the server with specified allowed commands.
Otherwise, it starts the client and sends the command to the server.
If no command is provided, it starts a shell on the host.

What's the point?

The main difference between hrun and host-spawn is that hrun relies on a socket server running on the host machine, while host-spawn uses the Flatpak DBus to communicate with the host, introducing 2 big dependencies.

This is not a replacement for host-spawn, but a different approach to the same problem on those systems where Flatpak or DBus are not available.

What is left to do?

• Add an option to restrict the commands that can be run
• Add support for creating shims for host binaries
• Switch from TCP to Unix sockets
• Code optimization
