Distrobox

Use any Linux distribution inside your terminal. Enable both backward and forward compatibility with software and freedom to use whatever distribution you’re more comfortable with. Distrobox uses podman or docker to create containers using the Linux distribution of your choice. The created container will be tightly integrated with the host, allowing sharing of the HOME directory of the user, external storage, external USB devices and graphical apps (X11/Wayland), and audio.

What it does

Simply put it's a fancy wrapper around podman or docker to create and start containers highly integrated with the hosts.

The distrobox environment is based on an OCI image. This image is used to create a container that seamlessly integrates with the rest of the operating system by providing access to the user's home directory, the Wayland and X11 sockets, networking, removable devices (like USB sticks), systemd journal, SSH agent, D-Bus, ulimits, /dev and the udev database, etc...

It implements the same concepts introduced by https://github.com/containers/toolbox but in a simplified way using POSIX sh and aiming at broader compatibility.

All the props go to them as they had the great idea to implement this stuff.

It is divided into 7 commands:

• distrobox-create - creates the container
• distrobox-enter - to enter the container
• distrobox-list - to list containers created with distrobox
• distrobox-rm - to delete a container created with distrobox
• distrobox-stop - to stop a running container created with distrobox
• distrobox-init - the entrypoint of the container (not meant to be used manually)
• distrobox-export - it is meant to be used inside the container, useful to export apps and services from the container to the host

It also includes a little wrapper to launch commands with distrobox COMMAND instead of calling the single files.

Please check the usage docs here and see some handy tips on how to use it

See it in action

Thanks to castrojo, you can see Distrobox in action in this explanatory video on his setup with Distrobox, Toolbx, Fedora Silverblue on his project ublue (check it out!)

Why

• Provide a mutable environment on an immutable OS, like Endless OS, Fedora Silverblue, OpenSUSE MicroOS or SteamOS3
• Provide a locally privileged environment for sudoless setups (eg. company-provided laptops, security reasons, etc...)
• To mix and match a stable base system (eg. Debian Stable, Ubuntu LTS, RedHat) with a bleeding-edge environment for development or gaming (eg. Arch, OpenSUSE Tumbleweed or Fedora with latest Mesa)
• Leverage high abundance of curated distro images for docker/podman to manage multiple environments

Refer to the compatiblity list for an overview of supported host's distro HERE and container's distro HERE.

Aims

This project aims to bring any distro userland to any other distro supporting podman or docker. It has been written in POSIX sh to be as portable as possible and not have problems with dependencies and glibc version's compatibility.

Refer HERE for a list of supported container managers and minimum supported versions.

It also aims to enter the container as fast as possible, every millisecond adds up if you use the container as your default environment for your terminal:

These are some sample results of distrobox-enter on the same container on my weak laptop from 2015 with 2 core cpu:

Total time for 100 container enters:

  ~$ time (for i in {1..100}; do distrobox-enter --name fedora-toolbox-35 -- whoami; done)
  real 0m36.209s
  user 0m6.520s
  sys 0m4.803s

Mean:

36.209s/100 = ~0.362ms mean time to enter the container

I would like to keep it always below the Doherty Treshold of 400ms.

Security implications

Isolation and sandboxing is not the main aim of the project, on the contrary it aims to tightly integrate the container with the host. The container will have complete access to your home, pen drives and so on, so do not expect it to be highly sandboxed like a plain docker/podman container or a flatpak.

⚠️ BE CAREFUL: if you use docker, or you use podman with the --root/-r flag, the containers will run as root, so root inside the rootful container can modify system stuff outside the container, if you have security concern for this, use podman that runs in rootless mode. Rootless docker is still not working as intended and will be included in the future when it will be complete.

That said, it is in the works to implement some sort of decoupling with the host, as discussed here: #28 Sandboxed mode

Basic usage

Create a new distrobox:

distrobox create -n test

Enter created distrobox:

distrobox enter test

Execute a command in a distrobox:

distrobox enter test -- command-to-execute

List running distroboxes:

distrobox list

Stop a running distrobox:

distrobox stop test

Remove a distrobox

distrobox rm test

You can check HERE for more advanced usage and check a comprehensive list of useful tips HERE

Configure Distrobox

Configuration files can be placed in the following paths, from the least important to the most important:

• /usr/share/distrobox/distrobox.conf
• /etc/distrobox/distrobox.conf
• ${HOME}/.config/distrobox/distrobox.conf
• ${HOME}/.distroboxrc

Example configuration file:

container_user_custom_home="/home/.local/share/container-home-test"
container_image="registry.opensuse.org/opensuse/toolbox:latest"
container_manager="docker"
container_name="test-name-1"
non_interactive="1"

Alternatively it is possible to specify preferences using ENV variables:

• DBX_CONTAINER_MANAGER
• DBX_CONTAINER_IMAGE
• DBX_CONTAINER_NAME
• DBX_NON_INTERACTIVE

Installation

Distrobox is packaged in the following distributions, if your distribution is on this list, you can refer to your repos for installation:

Thanks to the maintainers for their work: M0Rf30, alcir, dfaggioli, AtilaSaraiva, michel-slm

Else, if you like to live your life dangerously, or you want the latest release, you can trust me and simply run this in your terminal:

curl -s https://raw.githubusercontent.com/89luca89/distrobox/main/install | sudo sh

or if you want to select a custom directory to install without sudo:

curl -s https://raw.githubusercontent.com/89luca89/distrobox/main/install | sh -s -- --prefix ~/.local

Alternatively you can clone the project using git clone or using the latest release HERE.

Enter the directory and run ./install, by default it will attempt to install in ~/.local but if you run the script as root, it will default to /usr/local. You can specify a custom directory with the --prefix flag such as ./install --prefix ~/.distrobox.

Prefix explained: main distrobox files get installed to ${prefix}/bin whereas the manpages get installed to ${prefix}/share/man.

Check the Host Distros compatibility list for distro-specific instructions.

Dependencies

Distrobox depends on a container manager to work, you can choose to install either podman or docker. Please look in the Compatibility Table for your distribution notes.

---

Uninstallation

If you installed distrobox using the install script in the default install directory use this:

curl -s https://raw.githubusercontent.com/89luca89/distrobox/main/uninstall | sudo sh

or if you specified a custom path:

curl -s https://raw.githubusercontent.com/89luca89/distrobox/main/uninstall | sh -s -- --prefix ~/.local

Else if cloned the project using git clone or using the latest archive release from HERE,

enter the directory and run ./uninstall, by default it will assume the install directory was /usr/local if ran as root or ~/.local, you can specify another directory if needed with ./uninstall --prefix ~/.local
