Description

We deployed Hue on AWS EKS with IPv6 configurations in three Public subnets of VPC. Also, deployed AWS ALB controller and mapped the ingress associated with ALB to Route 53 record name. However, when we try to access huev6.data-core-dev.aws.idealo.cloud from browser, it shows 502 Bad Gateway and the target groups shows the health status as unhealthy. We also allowed traffic from ALB to EKS nodes security groups.

Below is ingress.yaml file:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-hue
  annotations:
    alb.ingress.kubernetes.io/scheme: internet-facing
    alb.ingress.kubernetes.io/ip-address-type: dualstack
    alb.ingress.kubernetes.io/target-type: ip
    alb.ingress.kubernetes.io/healthcheck-port: '8888'
    alb.ingress.kubernetes.io/healthcheck-protocol: HTTP
    alb.ingress.kubernetes.io/healthcheck-path: /hue/editor
    alb.ingress.kubernetes.io/load-balancer-attributes: idle_timeout.timeout_seconds=600
    external-dns.alpha.kubernetes.io/hostname: huev6.data-core-dev.aws.idealo.cloud
spec:
  ingressClassName: alb
  rules:
    - http:
        paths:
        - path: /
          pathType: Prefix
          backend:
            service:
              name: hue
              port:
                number: 8888

Versions:
AWS EKS v1.22
aws-load-balancer-controller:v2.6.1
Hue v4.11

Steps To Reproduce

1-Create EKS cluster using IPv6 family using eksctl create cluster -f cluster-config.yaml command
2-Install AWS ALB ingress controller
3-Apply all manifest files of Hue on EKS
4-Establish a linkage between the ingress linked with ALB and the Route53 record name
5-Attempting to access huev6.data-core-dev.aws.idealo.cloud from a browser results in a "502 Bad Gateway" error. Additionally, in the AWS Console, the target groups display an unhealthy health status.

IPV6 issue should be solved by setting following property in hue.ini.

[desktop]
http_host=[::]

By default, hue takes ipv4 value 0.0.0.0 and its equivalent in ipv6 is [::].

We have tested it by adding this property and we are able to access Hue fine.
