Migrate virtual machines to Kubernetes with this new tool
|
||||
======
|
||||
Transition your virtualized workloads to Kubernetes with Forklift.
|
||||
![Containers on a ship on the ocean][1]
|
||||
|
||||
In 2017, the [KubeVirt][2] team [launched][3] the project to manage virtual machines (VMs) alongside containers in [Kubernetes][4]. The open source project's intent was to make VMs first-class citizens in this environment.
|
||||
|
||||
Since its introduction at [Open Source Summit 2018][5], KubeVirt has continued maturing and growing. It's reached more than 200 stars on GitHub and even introduced its own event, [KubeVirt Summit][6], in February 2021.
|
||||
|
||||
![KubeVirt architecture][7]

||||

||||

|
||||
|
||||
KubeVirt is the foundation underneath [OpenShift Virtualization][9], which helps developers bring VMs into containerized workflows.
|
||||
|
||||
### Leveraging VMs in Kubernetes
|
||||
|
||||
KubeVirt enables you to use Kubernetes natives on VMs. This means they can connect to pod networks that are accessible using standard Kubernetes methods, including Service, Route, Pipelines, etc. Network policies apply to VM pods the same way they apply to application pods, providing a consistent model to manage VM-to-pod (and vice-versa) communication.
|
||||
|
||||
A real-world example of this is the way an aeronautical company leveraged old simulator software. It injected models with artificial intelligence and machine learning (AI/ML), then automatically deployed and tested them on a VM-based simulator. This allowed it to fully automate obtaining test results and new telemetry training data using Kubernetes and [Kubeflow][10].
|
||||
|
||||
![VM-creation workflow][11]
|
||||
|
||||
(Konveyor, [CC BY-SA 4.0][12])
|
||||
|
||||
[Konveyor.io][13] is an open source project that helps transition existing workloads (development, test, and production) to Kubernetes. Its tools include [Crane][14], to move containers from one Kubernetes platform to another; [Move2Kube][15], to bring workloads from Cloud Foundry to Kubernetes; and [Tackle][16], to analyze Java applications to modernize them by making them more standard and portable for the runtimes available in containerized platforms like Kubernetes.
|
||||
|
||||
These tools are useful in transformation patterns, but many projects want to utilize Kubernetes at earlier stages to become more agile and productive. On the infrastructure side, these benefits can include blue/green load balancing, route management, declarative deployments, or (depending on how you deploy) easier upgrades due to immutable infrastructure. On the development side, they may include integrating continuous integration/continuous development (CI/CD) pipelines with the platform, getting apps to production faster, self-provisioning resources, or integrating health checks and monitoring.
|
||||
|
||||
KubeVirt can help you by running workloads as VMs in a Kubernetes environment. It enables you to onboard your workloads to Kubernetes quickly, enjoy its benefits, and steadily modernize your workloads over time. But, you still have the issue of bringing your VMs from your traditional virtualization platform to the modern Kubernetes platform. This is where Konveyor's [Forklift][17] project comes in.
|
||||
|
||||
### About Forklift
|
||||
|
||||
Forklift migrates virtualized workloads from different sources to Kubernetes using KubeVirt. It is designed to make the task simple so that you can migrate anything from one or two machines to hundreds of them.
|
||||
|
||||
Migration is a simple, three-stage process:
|
||||
|
||||
1. Connect to an existing virtualization platform (known as a "source provider") and to a Kubernetes environment (a "target provider").
|
||||
2. Map network and storage resources from the source provider to the target provider, looking for equivalent resources in both.
|
||||
3. Select virtual machines to migrate and assign the network and storage mappings to formulate a migration plan. Then run it.
|
||||
|
||||
|
||||
|
||||
### How to get started
|
||||
|
||||
To get started with Forklift, first, you need a compatible source provider. You also need a Kubernetes environment with KubeVirt 0.40 or newer and bare-metal nodes (although for testing, you can use nested virtualization). Configure your storage classes with read-write-execute (RWX) capabilities, and use [Multus][18] to configure your networks to match the ones your VMs are using in the source provider. (If you can't do this, no worries; you also have the option to rearrange IP addressing.)
|
||||
|
||||
Finally, [install Forklift][19] on your Kubernetes using the provided operator, and access the user interface to start running your first test migrations.
|
||||
|
||||
Forklift is the upstream version of Red Hat's [Migration Toolkit for Virtualization][20]. Therefore, if you want to use it in a production environment, you may wish to consider using that supported version of the tool.
|
||||
|
||||
Happy migrating!

用这个新工具将虚拟机迁移到 Kubernetes 上
|
||||
======
|
||||
用 Forklift 将你的虚拟化工作负载过渡到 Kubernetes。
|
||||
![Containers on a ship on the ocean][1]
|
||||
|
||||
2017 年，[KubeVirt][2] 团队[发起][3]了一个在 [Kubernetes][4] 中与容器一起管理虚拟机 （VM） 的项目。这个开源项目的意图是让虚拟机成为这个环境中的一等公民。
|
||||
|
||||
自从在 [2018 年开源峰会][5]上推出以来，KubeVirt 一直在不断成熟和发展。它在 GitHub 上已经达到了 200 多颗星，甚至在 2021 年 2 月推出了自己的活动：[KubeVirt 峰会][6]。
|
||||
|
||||
![KubeVirt architecture][7]
|
||||
|
||||
KubeVirt架构（© 2020,[Red Hat OpenShift][8]）
|
||||
|
||||
KubeVirt 是 [OpenShift 虚拟化][9]的基础，它帮助开发者将虚拟机带入容器化工作流程。
|
||||
|
||||
### 在 Kubernetes 中使用虚拟机
|
||||
|
||||
KubeVirt 使你能够在虚拟机上原生使用 Kubernetes。这意味着它们可以连接到使用标准 Kubernetes 方法访问的 pod 网络，包括服务、路由、管道等。应用于虚拟机 pod 的网络策略与应用于应用的 pod 方式相同，它提供一个一致的模型来管理虚拟机到 pod （反之亦然）的通信。
|
||||
|
||||
这方面的一个真实例子是一家航空公司利用旧的模拟器软件的方式。它注入了人工智能和机器学习 （AI/ML） 的模型，然后在基于虚拟机的模拟器上自动部署和测试它们。这使得它能够使用 Kubernetes 和 [Kubeflow][10] 完全自动化地获得测试结果和新的遥测训练数据。
|
||||
|
||||
![VM-creation workflow][11]
|
||||
|
||||
（Konveyor, [CC BY-SA 4.0][12]）
|
||||
|
||||
[Konveyor.io][13] 是一个开源项目，帮助现有工作负载（开发、测试和生产）过渡到 Kubernetes。其工具包括 [Crane][14]，将容器从一个 Kubernetes 平台转移到另一个平台、[Move2Kube][15]，将工作负载从 Cloud Foundry 带到 Kubernetes，以及 [Tackle][16]，分析 Java 应用，使其对 Kubernetes 等容器化平台中的运行时更加标准和便携，从而使其现代化。
|
||||
|
||||
这些工具在转化模式中很有用，但许多项目希望在早期阶段利用 Kubernetes，以变得更加敏捷和富有成效。在基础设施方面，这些好处可能包括蓝/绿负载均衡、路由管理、声明式部署，或（取决于你的部署方式）由于不可变的基础设施而更容易升级。在开发方面，它们可能包括将持续集成/持续开发 （CI/CD） 管道与平台整合，使应用更快地投入生产，自我提供资源，或整合健康检查和监控。
|
||||
|
||||
KubeVirt 可以通过在 Kubernetes 环境中作为虚拟机运行工作负载来帮助你。它能让你的工作负载迅速使用 Kubernetes，享受它的好处，并随着时间的推移稳步实现工作负载的现代化。但是，你仍然有一个问题，就是把你的虚拟机从传统的虚拟化平台带到现代的 Kubernetes 平台。这就是 Konveyor 的 [Forklift][17] 项目的意义所在。
|
||||
|
||||
### 关于 Forklift
|
||||
|
||||
Forklift 使用 KubeVirt 将不同来源的虚拟化工作负载迁移到 Kubernetes。它被设计成使任务变得简单，以便你可以从一两台机器到数百台机器迁移任何东西。
|
||||
|
||||
迁移是一个简单的、三阶段的过程：
|
||||
|
||||
1. 连接到一个现有的虚拟化平台（称为“源提供者”）和一个 Kubernetes 环境（“目标提供者”）。
|
||||
2. 将网络和存储资源从源提供者映射到目标提供者，在两者中寻找相同的资源。
|
||||
3. 选择要迁移的虚拟机，分配网络和存储映射，制定迁移计划。然后运行它。
|
||||
|
||||
|
||||
|
||||
### 如何开始
|
||||
|
||||
要开始使用 Forklift，首先，你需要一个兼容的源提供商。你还需要一个带有 KubeVirt 0.40 或更新版本的 Kubernetes 环境和裸机节点（尽管为了测试，你可以使用嵌套虚拟化）。用读-写-执行 （RWX） 功能配置你的存储类，并使用 [Multus][18] 配置你的网络，以匹配你的虚拟机在源提供者中使用的网络。（如果你不能这样做，也不用担心。你也可以选择重新分配 IP 地址。）
|
||||
|
||||
最后，使用提供的操作者在你的 Kubernetes 上[安装 Forklift][19]，并进入用户界面，开始运行你的第一次测试迁移。
|
||||
|
||||
Forklift 是 Red Hat 的[虚拟化迁移工具套件][20]的上游版本。因此，如果你想在生产环境中使用它，你可以考虑使用该工具的支持版本。
|
||||
|
||||
迁移愉快！
