Run a Linux virtual machine in Podman
|
||||
======
|
||||
Use Podman Machine to create a basic Fedora CoreOS VM to use with
|
||||
containers and containerized workloads.
|
||||
![woman on laptop sitting at the window][1]
|
||||
|
||||
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`
|
||||

|
||||
[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.

在 Podman 中运行一个 Linux 虚拟机
|
||||
======
|
||||
使用 Podman Machine 创建一个基本的 Fedora CoreOS 虚拟机来使用容器和容器化工作负载。
|
||||
![woman on laptop sitting at the window][1]
|
||||
|
||||
Fedora CoreOS 是一个自动更新、基于最小 [rpm-ostree][2]的 操作系统，用于安全地、大规模地运行容器化工作负载。
|
||||
|
||||
[Podman][3] “是一个用于管理容器和镜像、挂载到这些容器中的卷，以及由这些容器组组成的 pod 的工具。Podman 基于 libpod，它是一个容器生命周期管理库”。
|
||||
|
||||
当你使用 [Podman Machine][4] 时，神奇的事情发生了，它可以帮助你创建一个基本的 Fedora CoreOS 虚拟机（VM）来使用容器和容器化工作负载。
|
||||
|
||||
### 开始使用 Podman Machine
|
||||
|
||||
第一步是安装 Podman。如果你已经安装了最新版本的 Podman，你可以跳过这个步骤。在我的 Fedora 34 机器上，我用以下方式安装 Podman：
|
||||
|
||||
|
||||
```
|
||||
`$ sudo dnf install podman`
|
||||
```
|
||||
|
||||
我使用的是 podman-3.2.2-1.fc34.x86_64。
|
||||
|
||||
### 初始化 Fedora CoreOS
|
||||
|
||||
Podman 安装完成后，用以下方法初始化它：
|
||||
|
||||
|
||||
```
|
||||
❯ podman machine init vm2
|
||||
Downloading VM image: fedora-coreos-34.20210626.1.0-qemu.x86_64.qcow2.xz: done
|
||||
Extracting compressed file
|
||||
```
|
||||
|
||||
这个命令创建了 `vm2`，并下载了 .xz 格式的 Fedora CoreOS 的 qcow2 文件并将其解压。
|
||||
|
||||
### 列出你的虚拟机
|
||||
|
||||
了解你的虚拟机和它们的状态是很重要的，`list` 命令可以帮助你做到这一点。下面的例子显示了我所有的虚拟机的名称，它们被创建的日期，以及它们最后一次启动的时间：
|
||||
|
||||
|
||||
```
|
||||
❯ 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
|
||||
```
|
||||
|
||||
### 启动一个虚拟机
|
||||
|
||||
要启动一个虚拟机，请运行：
|
||||
|
||||
|
||||
```
|
||||
❯ podman machine start
|
||||
Waiting for VM …
|
||||
```
|
||||
|
||||
### SSH 到虚拟机
|
||||
|
||||
你可以使用 SSH 来访问你的虚拟机，并使用它来运行工作负载，而没有任何麻烦的设置：
|
||||
|
||||
|
||||
```
|
||||
❯ podman machine ssh
|
||||
Connecting to vm podman-machine-default. To close connection, use `~.` or `exit`

|
||||
[core@localhost ~]$
|
||||
```
|
||||
|
||||
目前，Podman 只支持一次运行一个虚拟机。
|
||||
|
||||
### 停止你的虚拟机
|
||||
|
||||
要停止运行中的虚拟机，请使用 `stop` 命令：
|
||||
|
||||
|
||||
```
|
||||
❯ podman machine stop
|
||||
|
||||
[core@localhost ~]$ Connection to localhost closed by remote host.
|
||||
Connection to localhost closed.
|
||||
Error: exit status 255
|
||||
```
|
||||
|
||||
我希望这能帮助你开始使用 Podman Machine。请试一试，并在评论中告诉我们你的想法。
