部署到 Istio（使用 Kubernetes）的 Jhipster 无法正确加载

Question

我正在将 Jhipster 应用程序部署到 Kubernetes 环境，并使用 Istio 进行网络连接。

下面是我的虚拟服务。请注意，当 prefix 设置为 / 时，一切正常。但是我在这个集群上有几个应用运行，所以我需要将它映射到 /mywebsite。

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
 name: ingress
spec:
 hosts:
 - "*"
 gateways:
 - mywebsite-gateway
 http:
 - match:
   - uri:
       prefix: /mywebsite
   route:
   - destination:
       host: mywebsite
       port:
         number: 80
   websocketUpgrade: true

当我访问该应用程序时，出现以下一组错误：

mywebsite:3 GET http://mywebsite.com:31380/app/vendor.bundle.js net::ERR_ABORTED 404 (Not Found)

mywebsite:1 Unchecked runtime.lastError: The message port closed before a response was received.

我不确定它为什么要尝试 /app/vendor.bundle.js。我认为它应该转到 /mywebsite/app/vendor.bundle.js。虽然当我手动转到此页面时，我得到了 Your request cannot be processed

同样在我的 index.html 中，我有 <base href="./" />，它一直存在，因为我读到它是一个可能的解决方案。

正如您在评论中提到的那样

I set new HtmlWebpackPlugin({ baseUrl: '/myapp/' }) in the webpack ... and in the index.html. I get some new errors (ie. can't find favicon), but still the site doesn't load as doesn't seem to find the javascript or soemthing – Mike K

它应该是这样工作的。它不会加载 javascript 并且可能 css/img 因为你没有为此显示 istio uri。

所以这里的解决方案是

制作新的baseUrl和basehref，例如/myapp
使用 /myapp 前缀或任何前缀创建虚拟服务并重写 /myapp
为您的 javascript/css/img 文件夹路径创建额外的 uri

看看这个example

Let’s break down the requests that should be routed to Frontend:

Exact path / should be routed to Frontend to get the Index.html

Prefix path /static/* should be routed to Frontend to get any static files needed by the frontend, like Cascading Style Sheets and JavaScript files.

Paths matching the regex ^.*.(ico|png|jpg)$ should be routed to Frontend as it is an image, that the page needs to show.

http:
  - match:
    - uri:
        exact: /
    - uri:
        exact: /callback
    - uri:
        prefix: /static
    - uri:
        regex: '^.*\.(ico|png|jpg)$'
    route:
    - destination:
        host: frontend             
        port:
          number: 80
