podman-machine-init - Initialize a new virtual machine


podman machine init [options] [name]


Initialize a new virtual machine for Podman.

Podman on macOS requires a virtual machine. This is because containers are Linux - containers do not run on any other OS because containers’ core functionality are tied to the Linux kernel.

podman machine init initializes a new Linux virtual machine where containers are run. SSH keys are automatically generated to access the VM, and system connections to the root account and a user account inside the VM are added.

By default, the VM distribution is Fedora CoreOS. Fedora CoreOS upgrades come out every 14 days and are detected and installed automatically. The VM will be rebooted during the upgrade. For more information on updates and advanced configuration, please see the FCOS update docs here and here.



Number of CPUs.


Size of the disk for the guest VM in GB.


Fully qualified path of the ignition file.

If an ignition file is provided, the file will be copied into the user’s CONF_DIR and renamed. Additionally, no SSH keys will be generated nor will a system connection be made. It is assumed that the user will do these things manually or handle otherwise.


Fully qualified path or URL to the VM image. Can also be set to testing, next, or stable to pull down default image. Defaults to testing.

--memory, -m=number

Memory (in MB).
