A user reported that it was a surprise to receive an unsupported os error when trying to use `podman machine os apply` with WSL machines. This is intentional however the documentation needed to be updated to explicitly state why (it is not based on FCOS). Fixes: #25435 Signed-off-by: Brent Baude <bbaude@redhat.com>

## NAME
|
|
podman\-machine\-os\-apply - Apply an OCI image to a Podman Machine's OS
|
|
|
|
## SYNOPSIS
|
|
**podman machine os apply** [*options*] *image* [vm]
|
|
|
|
## DESCRIPTION
|
|
|
|
Apply machine OS changes from an OCI image.
|
|
|
|
VM's that use OS's that use rpm-ostreee have the capability to rebase itself from the content of an OCI image.
|
|
`podman machine image apply` takes an OCI image with container native ostree functionality and rebases itself on that image.
|
|
|
|
By default, Podman machines on Mac, Linux, and Windows Hyper-V use a customized rpm-ostree based distribution (Fedora CoreOS). Machines based on Microsoft WSL use a
|
|
customized Fedora distribution and cannot be updated with this command.
|
|
|
|
Note: WSL-based machines are upgradable by using the `podman machine ssh <machine_name>` command followed by `sudo dnf update`. This can, however, result in unexpected results in
|
|
Podman client and server version differences.
|
|
|
|
Podman machine images are stored as OCI images at `quay.io/podman/machine-os`. When applying an image using this
|
|
command, the fully qualified OCI reference name must be used including tag where the tag is the
|
|
version of Podman that is inside the VM. By default, Podman will attempt to pull only the statement
|
|
version as itself.
|
|
|
|
For more information, see the [rpm-ostree documentation](https://coreos.github.io/rpm-ostree/container/).
|
|
|
|
The default machine name is `podman-machine-default`. If a machine name is not specified as an argument,
|
|
then the OS changes will be applied to `podman-machine-default`.
|
|
|
|
## OPTIONS
|
|
|
|
#### **--help**
|
|
|
|
Print usage statement.
|
|
|
|
#### **--restart**
|
|
|
|
Restart VM after applying changes.
|
|
|
|
## EXAMPLES
|
|
|
|
Update the default Podman machine to the latest development version of the
|
|
bootable OCI image.
|
|
|
|
Note: This may result in having a newer Podman version inside the machine
|
|
than the client. Unexpected results may occur.
|
|
|
|
Update the default Podman machine to the most recent Podman 5.4 bootable
|
|
OCI image.
|
|
```
|
|
$ podman machine os apply quay.io/podman/machine-os:5.4
|
|
```
|
|
|
|
Update the specified Podman machine to latest Podman 5.3 bootable OCI image.
|
|
```
|
|
$ podman machine os apply quay.io/podman/machine-os:5.3 mymachine
|
|
```
