This is the full definition of the UBI-based toolbox image published for RHEL 8 >= 8.5 [1] at registry.access.redhat.com/ubi8/toolbox:8.7 and such. Note that the Dockerfile used to build this image was already available to the public [2], but didn't include all the files necessary to build it. The FROM line has been changed to registry.access.redhat.com/ubi8:8.7 and such so that it can be built outside Red Hat's build system and always points to the desired RHEL version.

[Toolbox](https://containertoolbx.org/) is a tool for Linux, which allows the
|
|
use of interactive command line environments for development and
|
|
troubleshooting the host operating system, without having to install software
|
|
on the host. It is built on top of [Podman](https://podman.io/) and other
|
|
standard container technologies from [OCI](https://opencontainers.org/).
|
|
|
|
Toolbox environments have seamless access to the user's home directory,
|
|
the Wayland and X11 sockets, networking (including Avahi), removable devices
|
|
(like USB sticks), systemd journal, SSH agent, D-Bus, ulimits, /dev and the
|
|
udev database, etc..
|
|
|
|
This is particularly useful on
|
|
[OSTree](https://ostree.readthedocs.io/en/latest/) based operating systems like
|
|
[Fedora CoreOS](https://coreos.fedoraproject.org/) and
|
|
[Silverblue](https://silverblue.fedoraproject.org/). The intention of these
|
|
systems is to discourage installation of software on the host, and instead
|
|
install software as (or in) containers — they mostly don't even have package
|
|
managers like DNF or YUM. This makes it difficult to set up a development
|
|
environment or troubleshoot the operating system in the usual way.
|
|
|
|
Toolbox solves this problem by providing a fully mutable container within
|
|
which one can install their favourite development and troubleshooting tools,
|
|
editors and SDKs. For example, it's possible to do `yum install ansible`
|
|
without affecting the base operating system.
|
|
|
|
However, this tool doesn't *require* using an OSTree based system. It works
|
|
equally well on Fedora Workstation and Server, and that's a useful way to
|
|
incrementally adopt containerization.
|
|
|
|
The toolbox environment is based on an [OCI](https://www.opencontainers.org/)
|
|
image. On Fedora this is the `fedora-toolbox` image. This image is used to
|
|
create a toolbox container that offers the interactive command line
|
|
environment.
|
|
|
|
Note that Toolbox makes no promise about security beyond what's already
|
|
available in the usual command line environment on the host that everybody is
|
|
familiar with.
