背景：目前worker节点只有一台，deployment起了俩个pod。通过更改其中一个pod中的代码来客观实现session保持。目前ingress-nginx版本为0.30.0

发现客户端并没有生产cookie，服务端也就相应的没有session保持了。

代码如下

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: nginx
  namespace: laravel
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
    nginx.ingress.kubernetes.io/affinity: cookie
    nginx.ingress.kubernetes.io/session-cookie-name: first-cookie
    nginx.ingress.kubernetes.io/session-cookie-expires: 60
spec:
  tls:
    - hosts:
      - nginx.maigengduo.com
      secretName: nginx-tls
  rules:
    - host: nginx.maigengduo.com
      http:
        paths:
          - path: /
            backend:
              serviceName: nginx-php7
              servicePort: 80

我看到官网中annotations中并没有session-cookie-hash。
