Podman v3.3 now has a podman machine included, different from podman-machine:
https://podman.io/community/meeting/notes/2021-04-06/#podman-on-mac-preview
That is a new feature based on QEMU and CoreOS, unlike the old one (described here)
which is based on Docker Machine and Boot2Docker, as was available in Docker Toolbox...
See also: https://boot2podman.github.io/2020/11/03/boot2podman-project.html
Podman Machine (old) is now deprecated. Users should try using Vagrant instead.
You can create a similar VM, running Fedora (for podman) or Ubuntu (for docker)
Details: https://boot2podman.github.io/2020/07/22/machine-replacement.html
Podman itself is only available for Linux systems, not Mac or Windows.
Machine lets you create Podman hosts on your computer. It creates servers with Podman on them, then configures the Podman client to talk to them.
| ❗ Only works with Podman v1, due to breaking changes in Podman v2 |
|---|
| For details see https://podman.io/blogs/2020/06/29/podman-v2-announce.html |
For Podman version 2, 3 and 4 please see the documentation at https://podman.io/
Binaries can be found in: https://github.com/boot2podman/machine/releases
Get the version for your operating system and architecture, and put it in your path, adding executable permissions if needed.
mv podman-machine.linux-amd64 <your-bin-dir>/podman-machine
chmod +x podman-machinemv podman-machine.darwin-amd64 <your-bin-dir>/podman-machine
chmod +x podman-machinepodman-machine.windows-amd64.exe -> podman-machine.exe
You also need a supported Virtual Machine environment, such as VirtualBox or QEMU.
You will also need an SSH client installed for the varlink bridge on windows, such as SSH for Windows
Additional VM environments are possible too, after installing third party machine drivers.
The default is to use the latest version of boot2podman.iso:
https://github.com/boot2podman/boot2podman/releases/latest/download/boot2podman.iso
108M boot2podman.iso
But it is also possible to use a version based on Fedora instead:
367M boot2podman-fedora.iso
The tool will automatically download, optionally with parameter:
--virtualbox-boot2podman-url
If the above URLs do not work, you can also download the file...
Then you can use a file:// URL to choose the ISO image to use.

tc@box:~$ exitYou can run the podman command over ssh:
$ podman-machine ssh box -- sudo podman versionShow the available commands using the help:
$ podman-machine ssh box -- sudo podman --helpIf you don't have ssh installed, you can run:
podman-machine --native-ssh ssh
Set up the $PODMAN_VARLINK_BRIDGE variable:
$ podman-machine env box --varlink
$ eval $(podman-machine env box --varlink)> podman-machine env box --varlink
> & podman-machine env box --varlink | Invoke-ExpressionThen the commands will run remotely over ssh:
$ podman-remote version
$ podman-remote --helpSee https://github.com/containers/libpod/blob/master/docs/source/markdown/podman-remote.1.md
Binaries can be found in: https://github.com/boot2podman/libpod/releases
Get the version for your operating system and architecture, and put it in your path:
podman-remote-linux -> podman-remote (or maybe just podman)
podman-remote-darwin -> podman
podman-remote-windows.exe -> podman.exe
Or you can use the pypodman tool remotely:
$ eval $(podman-machine env box)
$ pypodman version
$ pypodman --helpThis will use environment variables to connect.
See https://github.com/containers/python-podman/tree/master
Connect directly with varlink over the bridge:
$ eval $(podman-machine env box --varlink)
$ varlink call io.podman.GetVersion
$ varlink help io.podmanYou might need --bridge="$PODMAN_VARLINK_BRIDGE".
See https://github.com/varlink/libvarlink/tree/master/tool
Only files on the virtual machine are seen by containers.
$ ls /tmp/foo
bar
$ podman-machine ssh box -- sudo podman run -v /tmp/foo:/foo busybox ls /foo
error checking path "/tmp/foo": stat /tmp/foo: no such file or directoryThis means that files to be used must be located there.
There is currently no access to any network filesystems.
In order to copy files, you can use the command scp:
podman-machine scp [machine:][path] [machine:][path]To mount files locally using SSHFS, you can use mount:
podman-machine mount [machine:][path] [mountpoint]In order to make files persist, they need to be on a disk.
The default mountpoint (for /dev/sda1) is: /mnt/sda1
Depending on the driver, the machine might get its own IP.
$ podman-machine ip
192.168.99.101If you don't get a machine IP, then you can use SSH tunneling.
$ podman-machine ip
127.0.0.1Then you can forward local ports, over to the virtual machine.
From there, they can access any ports published by containers.
This is done by starting a ssh command, as a background process.
$ podman-machine ssh box -L 8080:localhost:8080 -N &
[1] 4229
$ podman-machine ssh box -- sudo podman run -d -p 8080:80 nginx
18fde6761ea5df5c5170bc5c8d6709401b70957175ab8f6269e6024d9e577110To stop the tunnel, just end the process (4229 above) using kill.
$ kill 4229
[1]+ Terminated podman-machine ssh box -L 8080:localhost:8080 -N
$ podman-machine ssh box -- sudo podman stop 18fde6761ea5
18fde6761ea5df5c5170bc5c8d6709401b70957175ab8f6269e6024d9e577110If you need to install e.g. git, you can download and install it:
$ tce-load -wi git
git.tcz.dep OK
...
git.tcz: OK
$ git --version
git version 2.18.0This was for the default tinycore distro, other ISO might differ...
These core driver plugins are bundled:
- Generic
- VirtualBox
- QEMU (KVM)
It is possible to add standalone drivers.
Cloud drivers are explicitly not supported.
Please use Kubernetes for that, instead.
Podman Machine is inspired by Docker Machine, which is a similar solution but for another popular container runtime.
