kubernetes sticky session 配置

kubernetes中经常需要配置sticky session,此时需要根据你使用的ingress controller来设置了。

1、Nginx Ingress

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginx-test
  annotations:
    nginx.ingress.kubernetes.io/affinity: "cookie"
    nginx.ingress.kubernetes.io/session-cookie-name: "route"
    nginx.ingress.kubernetes.io/session-cookie-expires: "172800"
    nginx.ingress.kubernetes.io/session-cookie-max-age: "172800"

spec:
  rules:
  - host: stickyingress.example.com
    http:
      paths:
      - backend:
          serviceName: http-svc
          servicePort: 80
        path: /

2、Traefik Ingress

---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: traefik
  labels:
    app: test
  name: test
spec:
  rules:
  - host: 192.168.1.2
    http:
      paths:
      - path: /
        backend:
          serviceName: test
          servicePort: 8080
---
apiVersion: v1
kind: Service
metadata:
  name: test
  labels:
    app: test
  annotations:
    traefik.ingress.kubernetes.io/affinity: "true"
    traefik.ingress.kubernetes.io/session-cookie-name: "sticky"
spec:
  type: NodePort
  ports:
  - port: 8080
    targetPort: 8080
    protocol: TCP
    name: http
  selector:
    app: demo

 

然后在外部Nginx的upstream配置ip_hash,即可实现 kubernetes sticky session。
