arcam

Fast sandboxed development container manager using podman, minimal permissions by default choose balance between security and convenience

NOTE: Version 0.1.X is considered alpha and may break compatability at any time

Experimental but all code since v0.1.1 was written inside arcam container

Originally named box

Features

• Sandboxed ephemeral container by default (podman defaults with network turned on)
• Pass through audio, wayland, ssh-agent easily on demand with flags or config
• Customize your experience per language, even per project
• Override dotfiles locally on demand, so you don't have to rebuild image to update dotfiles
• Automatic passwordless sudo (or su if not installed)
• Consistant development environment on any distro, especially useful on immutable distros like fedora atomic
• Offline use, container initialization process does not require internet connection (image has to be downloaded of course)

Planned Features

These are features that are planned but the details are debatable

• Provide support for devcontainer features
• Docker support

Installation

You can download binary for latest release here

Alternatively you can install it from crates.io

cargo install arcam

You can also install straight from git

cargo install --git https://github.com/sandorex/arcam

Custom Container Image

Making a custom container image is same as for any other container, to take full advantage of box keep following things in mind:

• Install sudo for nicer experience
• Any executable files in /init.d will be executed on start of the container as the user, you can use sudo or su for root access
• Put dotfiles in /etc/skel which will be copied to user home on start, note that it may be overriden at runtime using flags
• All data inside the container (not counting mounts) will be deleted when container stops, to add caching or presistant data use a named volume

For examples you can take a look at my container with neovim and all LSPs preinstalled

Comparison to Other Tools

Toolbox / Distrobox

Both are great at their job, to provide a seamless integration with the host but not sandboxing

Box provides sandbox by default approach where you choose where to sacrifice sandboxing for convenience
