Run a Linux virtual machine in Podman
|
||
======
|
||
Use Podman Machine to create a basic Fedora CoreOS VM to use with
|
||
containers and containerized workloads.

|
||
|
||
Fedora CoreOS is an automatically updating, minimal [rpm-ostree][2]-based operating system for running containerized workloads securely and at scale.
|
||
|
||
[Podman][3] "is a tool for managing containers and images, volumes mounted into those containers, and pods made from groups of containers. Podman is based on libpod, a library for container lifecycle management."
|
||
|
||
Magical things happen when you use [Podman Machine][4], a feature that helps you create a basic Fedora CoreOS virtual machine (VM) to use with containers and containerized workloads.
|
||
|
||
### Getting started with Podman Machine
|
||
|
||
The first step is to install Podman. If you already have the latest version of Podman installed, you can skip the step. On my Fedora 34 machine, I installed Podman with:
|
||
|
||
|
||
```
|
||
`$ sudo dnf install podman`
|
||
```
|
||
|
||
I'm using podman-3.2.2-1.fc34.x86_64.
|
||
|
||
### Initializing a Fedora CoreOS
|
||
|
||
Once Podman is installed, initialize it with:
|
||
|
||
|
||
```
|
||
❯ podman machine init vm2
|
||
Downloading VM image: fedora-coreos-34.20210626.1.0-qemu.x86_64.qcow2.xz: done
|
||
Extracting compressed file
|
||
```
|
||
|
||
This command creates `vm2` and downloads Fedora CoreOS's qcow2 file in .xz format and extracts it.
|
||
|
||
### Listing your VMs
|
||
|
||
It's always important to know your VMs and their status, and the `list` command helps with that. The following example shows the names of all my VMs, the date they were created, and the last time they were up:
|
||
|
||
|
||
```
|
||
❯ podman machine list
|
||
NAME VM TYPE CREATED LAST UP
|
||
podman-machine-default* qemu 6 days ago Currently running
|
||
vm2 qemu 11 minutes ago 11 minutes ago
|
||
```
|
||
|
||
### Starting a VM
|
||
|
||
To start a VM, run:
|
||
|
||
|
||
```
|
||
❯ podman machine start
|
||
Waiting for VM …
|
||
```
|
||
|
||
### SSHing into the VM
|
||
|
||
You can use secure shell (SSH) to access your VM and use it to run workloads without any setup hassles:
|
||
|
||
|
||
```
|
||
❯ podman machine ssh
|
||
Connecting to vm podman-machine-default. To close connection, use `~.` or `exit`
|
||
Fedora CoreOS 34.20210611.1.0

[core@localhost ~]$ uname -a
|
||
Linux localhost 5.12.9-300.fc34.x86_64 #1 SMP Thu Jun 3 13:51:40 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
|
||
[core@localhost ~]$
|
||
```
|
||
|
||
Currently, Podman only supports running one VM at a time.
|
||
|
||
### Stopping your VM
|
||
|
||
To stop a running VM, use the `stop` command:
|
||
|
||
|
||
```
|
||
❯ podman machine stop
|
||
|
||
[core@localhost ~]$ Connection to localhost closed by remote host.
|
||
Connection to localhost closed.
|
||
Error: exit status 255
|
||
```
|
||
|
||
I hope this helps you get started with Podman Machine. Give it a try, and let us know what you think in the comments.
