如何从 EKS 集群为 Django 提供静态文件？

Question

我是 Kubernetes 新手。通过阅读一些博客和文档，我成功地创建了 EKS 集群。我正在为我的 Django 应用程序使用 ALB（第 7 层负载平衡）。为了控制 routes/paths，我使用了 ALB 入口控制器。但是我无法为 Django 管理员提供我的静态内容。我知道我需要一个网络服务器（Nginx）来为我的静态文件提供服务。我不确定如何配置以提供静态文件。注意：（我不想使用白噪声）

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

这是我正在使用的入口 yaml。但是每当我尝试访问我的 Django 管理员时，它都没有加载 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

我解决了使用 Django BE 和 Nginx 反向代理创建 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Service（和Ingress）中，指向Nginx 80端口。

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

我安装的路径错误。所以新的部署文件是：

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/
