Boot2Podman Fedora ISO

The regular boot2podman.iso is based on Tiny Core Linux:

https://github.com/boot2podman/boot2podman

There is now an alternative version, based on Fedora Linux:

https://github.com/boot2podman/boot2podman-fedora-iso

Both versions will do the same thing, in that they will both offer the Podman varlink socket.

The Podman Machine can set up virtual machines for either, by using the “url” parameters.

Tiny Core

This is a minimal system, that runs entirely from RAM and uses init(1).

The package manager uses TCZ packages, handled by the tce-load program.

The currently used version is CorePure64 (9.x)

See: https://en.wikipedia.org/wiki/Tiny_Core_Linux

Fedora

This is a full system, that boots a regular image and uses systemd(1).

The package manager uses RPM packages, handled by the dnf program.

The currently used version is Fedora (28)

See: https://en.wikipedia.org/wiki/Fedora_(operating_system)

Others

There are some other similar projects, not yet supported by podman-machine.

Most are intended for clusters and Kubernetes, rather than just running Podman.

Minikube

This is a Linux distribution made with BuildRoot, and offers machine compatibility.

It replaces the original boot2docker.iso, adding software and moving to systemd.

See: https://kubernetes.io/docs/setup/minikube/

Minishift

Similar to minikube, but intended for running OpenShift rather than Kubernetes.

It uses a different image based on CentOS, to replace the one made with BuildRoot.

See: https://docs.okd.io/latest/minishift/getting-started/

CoreOS

One alternative to these, is Container Linux, from CoreOS.

See: https://en.wikipedia.org/wiki/Container_Linux_by_CoreOS

Atomic

Another alternative is Atomic Host, from Project Atomic.

See: http://www.projectatomic.io/docs/introduction/ (Fedora)

Fedora CoreOS

Fedora CoreOS is an automatically updating, minimal, monolithic, container-focused operating system, designed for clusters but also operable standalone, optimized for Kubernetes but also great without it.

It aims to combine the best of both CoreOS Container Linux and Fedora Atomic Host

Eventually it will appear at https://coreos.fedoraproject.org/
