Creates a new toolbox container. You can then use the
toolbox enter command to interact with the container at any point.
A toolbox container is an OCI container created from an OCI image. On Fedora, the default image is known as
fedora-toolbox:N, where N is the release of the host. If the image is not present locally, then it is pulled from a well-known registry like
registry.fedoraproject.org. Other images may be used on other host operating systems. If the host is not recognized, then the Fedora image will be used.
The container is created with
podman create, and its entry point is set to
By default, a toolbox container is named after its corresponding image. If the image had a tag, then the tag is included in the name of the container, but it's separated by a hyphen, not a colon. A different name can be assigned by using the CONTAINER argument.
A toolbox container seamlessly integrates with the rest of the operating system by providing 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..
The user ID and account details from the host is propagated into the toolbox container, SELinux label separation is disabled, and the host file system can be accessed by the container at /run/host. The container has access to the host's Kerberos credentials cache if it's configured to use KCM caches.
A toolbox container can be identified by the
com.github.containers.toolbox label or the
The entry point of a toolbox container is the
toolbox init-container command which plays a role in setting up the container, along with the options passed to
A key feature of toolbox containers is their entry point, the
toolbox init-container command.
OCI containers are inherently immutable. Configuration options passed through
podman create are baked into the definition of the OCI container, and can't be changed later. This means that changes and improvements made in newer versions of Toolbox can't be applied to pre-existing toolbox containers created by older versions of Toolbox. This is avoided by using the entry point to configure the container at runtime.
The entry point of a toolbox container customizes the container to fit the current user by ensuring that it has a user that matches the one on the host, and grants it
Crucial configuration files, such as
/etc/timezone, inside the container are kept synchronized with the host. The entry point also bind mounts various subsets of the host's filesystem hierarchy to their corresponding locations inside the container to provide seamless integration with the host. This includes
/var/log/journal and others.
On some host operating systems, important paths like
/mnt are symbolic links to other locations. The entry point ensures that paths inside the container match those on the host, to avoid needless confusion.
- DISTRO, -d DISTRO
Create a toolbox container for a different operating system DISTRO than the host. Cannot be used with
- NAME, -i NAME
Change the NAME of the image used to create the toolbox container. This is useful for creating containers from custom-built images. Cannot be used with
If NAME does not contain a registry, the local image storage will be consulted, and if it's not present there then it will be pulled from a suitable remote registry.
- RELEASE, -r RELEASE
Create a toolbox container for a different operating system RELEASE than the host. Cannot be used with
Create a toolbox container using the default image matching the host OS
$ toolbox create
Create a toolbox container using the default image for Fedora 36
$ toolbox create --distro fedora --release f36
Create a custom toolbox container from a custom image
$ toolbox create --image bar foo
