如何为Django提供EKS集群中的静态文件？

Question

我是库伯内特斯的新手。通过阅读一些博客和文档，我成功地创建了EKS集群。我使用ALB(第7层负载平衡)作为我的Django应用程序。用于控制我使用的ALB入口控制器的路由/路径。但我无法为Django管理员提供静态内容。我知道我需要一个need服务器(Nginx)来服务我的静态文件。我不知道如何配置来提供静态文件。注意事项：(我不想使用whitenoise)

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: "backend-ingress"
  annotations:
    kubernetes.io/ingress.class: alb
    alb.ingress.kubernetes.io/scheme: internet-facing
    alb.ingress.kubernetes.io/subnets: subnet-1, subnet-2, subnet-3
    alb.ingress.kubernetes.io/certificate-arn: arn:aws:acm:ap-southeast-1:***:certificate/*
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}, {"HTTPS":443}]'
    alb.ingress.kubernetes.io/actions.ssl-redirect: '{"Type": "redirect", "RedirectConfig": { "Protocol": "HTTPS", "Port": "443", "StatusCode": "HTTP_301"}}'
  labels:
    app: stage
spec:
  rules:
    - host: *.somedomain.com
      http:
        paths:
          - path: /*
            backend:
              serviceName: backend-service
              servicePort: 8000

这是我用的入口yaml。但是，每当我试图访问Django管理员时，它都不会加载css和js文件。

部署文件：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: server-dashboard-backend
  labels:
    app: backend
spec:
  replicas: 2
  selector:
    matchLabels:
      app: backend
  template:
    metadata:
      labels:
        app: backend
    spec:
      volumes:
        - name: staticfiles
          emptyDir: {}
      containers:
       - name: server-dashboard 
         image: *.dkr.ecr.ap-southeast-1.amazonaws.com/*:4
      volumeMounts:
            - name: staticfiles
              mountPath: /data  
         lifecycle:
            postStart:
              exec:
                command: ["/bin/sh", "-c" , "cp -r /static /data/"]

       - name: nginx
         image: nginx:stable
         ports:
            - containerPort: 80
         volumeMounts:
            - name: staticfiles
              mountPath: /data

我已经解决了这个问题。我删除了命令["/bin/sh", "-c", "cp -r /path/to/staticfiles /data/"]

我走错路了。因此，新的部署文件是：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: server-dashboard-backend
  labels:
    app: backend
spec:
  replicas: 2
  selector:
    matchLabels:
      app: backend
  template:
    metadata:
      labels:
        app: backend
    spec:
      volumes:
        - name: staticfiles
          emptyDir: {}

      containers:
       - name: server-dashboard 
         image: *.dkr.ecr.ap-southeast-1.amazonaws.com/*:4
         volumeMounts:
            - name: staticfiles
              mountPath: /usr/src/code/static
          

       - name: nginx
         image: nginx:stable
         ports:
            - containerPort: 80
         volumeMounts:
            - name: staticfiles
              mountPath: /usr/share/nginx/html/static/

我解决了使用Django BE和Nginx反向代理创建一个pod的问题，共享静态文件卷：

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp
  labels:
    app: myapp
spec:
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
    spec:
      volumes:
        - name: staticfiles
          emptyDir: {}
      containers:
        - name: nginx
          image: ...
          ports:
            - containerPort: 80
          volumeMounts:
            - name: staticfiles
              mountPath: /data

        - name: django
          image: ...
          ports:
            - containerPort: 8000
          volumeMounts:
            - name: staticfiles
              mountPath: /data
          lifecycle:
            postStart:
              exec:
                command: ["/bin/sh", "-c", "cp -r /path/to/staticfiles /data/"]

然后，在“服务”(和“进位”)中，指向Nginx 80端口。
