How to serve static contents in a kubernetes application

Question

I have a small java webapp comprising of three microservices - api-service,book-service and db-service all of which are deployed on a kubernetes cluster locally using minikube.

I am planning to keep separate UIs for api-service and book-service , with the common static files served from a separate pod, probably an nginx:alpine image.

I was able to create a front end that serves the static files from nginx:alpine referring to this tutorial.

I would like to use ingress-nginx controller for routing requests to the two services.

The below diagram crudely shows where I am now.

I am confused as to where I should place the pod that serves the static content, and how to connect it to the ingress resource.I guess that keeping a front end pod before ingress defeats the purpose of ingress-nginx controller. What is the best practice to serve static files. Appreciate any help. Thanks.

Answer 1

您似乎对以下事实感到困惑：在线浏览的用户会触发标准请求，以“下载”您的静态内容，和使用您的2个API（book和api）。访问您的API的不是提供静态内容的NGINX服务，而是用户的浏览器/应用程序，它们对静态内容和API完全相同（前者具有更多/特定的标头和数据，例如auth ... ）。

在图表上，您希望将新的static-service与book-service和api-service放置在完全相同的级别，即在后面。但是您的static-service将不会像其他db-service那样与apiVersion: extensions/v1beta1 kind: Ingress metadata: name: your-global-ingress annotations: nginx.ingress.kubernetes.io/rewrite-target: / spec: rules: - host: foo.bar.com http: paths: - path: /book-service backend: serviceName: book-service servicePort: 80 - path: /api-service backend: serviceName: api-service servicePort: 80 - path: / backend: serviceName: static-service servicePort: 80 链接。然后只需完成您的入口规则，并在本例中最后添加static-service：

foo.bar.com/book-service

在上面的示例中，您必须调整服务名称和端口，并选择希望用户访问API的路径：

• foo.bar.com/api-service用于您的图书服务
• foo.bar.com/用于api服务
• frame = camera.get_frame() frame_data = unicode(frame, "utf-8") ，即其他所有要用于静态服务的内容

Answer 2

您应该拥有3个不同的豆荚： - 静态的 -图书服务 -API服务

静态吊舱极有可能无法以彼此相同的速度缩放。

为每个部署创建服务。然后使用ingres在正确的端点上路由流量。

是您想要实现的目标吗？
