我有兴趣在我的ISTIO网关后面放置在AWS EC2实例中提供的应用程序。听起来，理想的情况是使用WorkloadEntry来定义端点，并使我可以轻松地将其放入群集等，等等。
在我阅读的文档中，提到在VM中使用Sidecar为此启用。我找不到的是如何在VM中使用边锋。吊舱中有很多关于边车的好东西，但是我不确定在VM上实施什么以及我将如何实现。也许边车所需的集成是要在第三方应用程序中实施复杂？也许没有边车，我可以做得更好？
我如何找到有关VM Sidecars的详细信息并将它们集成到网格中？
您什么时候决定将其作为WorkLoadEntry与仅仅是MESH_EXTERNAL SERVICENTRY？
I'm interested in putting a vendor provided application running in an AWS EC2 Instance behind my Istio gateway. It sounds like the ideal scenario is to use a WorkloadEntry to define the endpoint and make it easy to flex should I ever get this into the cluster, etc.
In the documentation I've read, there is mention of using a sidecar in the VM to enable this. What I've failed to find is how to use a sidecar in a VM. There's lots of good stuff about sidecars in a pod, but I'm not sure what it takes to implement on the VM and how I would even go about doing that. Maybe the integration needed for the sidecar would be to complex to implement in a 3rd party app? Maybe I can do this better without a Sidecar?
How do I find details on VM Sidecars and getting them integrated into the mesh?
When do you decide between implementing this as a WorkloadEntry vs simply a MESH_EXTERNAL ServiceEntry?

如果要将VM集成到K8S ISTIO环境中，则需要在VM上设置ISTIO：
If you want to integrate a VM into your k8s Istio environment, you need to setup Istio on your VM :
