Toolboxes
There historically have been a few versions of "toolbox", and we're probably at a point where it's more of a class of software than an individual project. I classify toolboxes as "A terminal front end to container runtimes focusing on transparent ease of use of container images". Someone smarter please make a better definition.
- Toolbx - Tool for containerized command line environments on Linux
- Toolbx Tuner - Toolbx Tuner is a tool to improve the experience with toolbx.
- Toolbx Images - Community maintained container images to use with toolbx (Check these out if you need other distros outside the default Fedora ones)
- toolbox-images - a collection of container images for usage with the toolbox command. This is an attempt at providing more feature parity with regard to toolboxes for distributions other than Fedora.
- Toolbox GUI - A graphical interface for interacting with Toolbox, written with GTK3 and Python
- Distrobox - Tool for containerized command line environments on Linux, distribution agnostic, supports a wide variety of containers , works both with podman and docker - This is a great tool to start with on your existing distro to learn working with day-to-day container workflows.
- BoxBuddy - A GUI manager for your Distroboxes, made with GTK4 and Libadwaita.
- devbox - Devbox is a command-line tool that lets you easily create isolated shells and containers.
- apx - The default package manager for VanillaOS, utilising Distrobox to manage containers for various distros on the user's behalf.
Core Tools
Things that are the building blocks for all the stuff we're talking about here.
- podman - Podman is a daemonless container engine for developing, managing, and running OCI Containers on your Linux System.
- gnome-shell-extension-containers - This neat extension lets you see what containers you have, start/stop/restart, pause, and shell into them right from the notification area.
- Podman Desktop - Manage different container engines from a single UI and tray icon
- Pods - a podman desktop application (formely known as Symfony)
- Flatpak - a utility for software deployment and package management for Linux. It is advertised as offering a sandbox environment in which users can run application software in isolation from the rest of the system.
Lower level tools
Most of us will not use these tools directly, but useful for developers:
- libostree (a.k.a. OSTree) - Operating system and container binary deployment and upgrades
- Upcoming experimental features in rpm-ostree
- flatpak-ostree-dedup-stats.py - script to show you how well the ostree deduplication is working, this one is neat
- apt2ostree - apt2ostree is used for building Debian/Ubuntu based ostree images. It performs the same task as debootstrap/multistrap but the output is an ostree tree rather than a rootfs in a directory.
- Image Builder - osbuild - Build Infrastructure for Operating Systems
- ABRoot - A utility which provides full immutability and atomicity to a Linux system, by transacting between two root filesystems. Updates are performed using OCI images, to ensure that the system is always in a consistent state.
- BootC - Transactional, in-place operating system updates using OCI/Docker container images. (Experimental)
- bootupd - Distribution-independent updates for bootloaders.
- Elemental Toolkit - A toolkit which allows container images to be bootable in VMs, baremetals, embedded devices, and much more. Elemental and derivatives share a common feature set, can be upgraded with a A/B mechanism, and upgrades are delivered with standard container registries.
- GoldBoot - a command-line utility that builds machine images for both servers and workstations alike.
- Arkdep - Toolkit for building, deploying and maintaining immutable, atomic, btrfs-based systems
- frzr - A deployment and automatic update mechanism for operating systems, utilizing pre-built read-only btrfs subvolumes.
