我在 EKS 集群上运行 AWS 上的 ALB。我正在尝试在路由上应用 Ingress 资源的更改,以便它指向不同的后端。
下面的 Ingresses 的唯一区别是后端规范。
为什么更新不起作用?如何更新 ALB 上的路由?
原始入口:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: my-ingress
namespace: default
annotations:
kubernetes.io/ingress.class: alb
alb.ingress.kubernetes.io/scheme: internet-facing
alb.ingress.kubernetes.io/backend-protocol: HTTP
alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}]'
labels:
app: api
type: ingress
spec:
backend:
serviceName: api-service
servicePort: 80
