npm packages are not found - SyntaxError: Unexpected token '<'

Question

我是运行 Kubernetes env (AKS) 中的反应容器 istio gateway

在本地环境中，使用 docker build && docker run

一切正常

在 Kubernetes 中，对于每个 npm 包，我得到的响应是 status code: 200, response content-type: text/html，响应内容是 index.html，这就是为什么我假设找不到包？

当检查 docker dist 内容时，我可以断言包在那里（例如 /dist/npm.babel.4fca54....chunk.js 存在
docker 图像是使用基础上下文构建的：docker build -t imagename --build-arg PUBLIC_URL=/base-app .
index.html 有效且包含有效的脚本声明。例如 <script type="text/javascript" src="/base-app/npm.babel.743f....chunk.js"></script>

默认情况下，Istio 将从 https://dev.myDomain.com/base-app/npm.babel.4fca5....chunk.js 代理到 http://pod_ip:8000/base-app/npm.babel.4fca5....chunk.js，据我所知，您的图像直接从 /dist 提供文件，因此 Istio 实际上应该代理到http://pod_ip:8000/npm.babel.4fca5....chunk.js;注意缺失的 /base-app/。为此，请尝试将 Istio 虚拟服务更新为：

- match:
  - uri:
      prefix: /base-app
  rewrite:
    uri: /
  route:
  - destination:
      host: svc-app
      port:
        number: 8000
