Configuring HTTPS Backend Services for a LoadBalancer Ingress

Notes and Constraints

• This function is available only in clusters of v1.23.8, v1.25.3, or later.
• Ingresses can interconnect with HTTPS backend services only when dedicated load balancers are used.
• When an ingress interconnects with an HTTPS backend service, the ingress protocol must be HTTPS.

Configuration Example

An ingress configuration example is as follows:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-test
  namespace: default
  annotations:
    kubernetes.io/elb.port: '443'
    kubernetes.io/elb.id: <your_elb_id>    # In this example, an existing dedicated load balancer is used. Replace its ID with the ID of your dedicated load balancer.
    kubernetes.io/elb.class: performance
    kubernetes.io/elb.pool-protocol: https  # Interconnected HTTPS backend service
    kubernetes.io/elb.tls-ciphers-policy: tls-1-2
spec:
  tls: 
    - secretName: ingress-test-secret
  rules:
    - host: ''
      http:
        paths:
          - path: '/'
            backend:
              service:
                name: <your_service_name>  # Replace it with the name of your target Service.
                port:
                  number: 80
            property:
              ingress.beta.kubernetes.io/url-match-mode: STARTS_WITH
            pathType: ImplementationSpecific
  ingressClassName: cce
