Redirecting away from "www"

[nicholas...@gmail.com]

Hello, I have an ALB set up for "domain.com". I'd like to know how to set up a redirect from "www.domain.com" to "domain.com". This is my current set up, which simply serves up "www.domain.com":

apiVersion: extensions/v1beta1

kind: Ingress

metadata:

name: redacted

namespace: default

annotations:

kubernetes.io/ingress.class: alb

alb.ingress.kubernetes.io/scheme: internet-facing

alb.ingress.kubernetes.io/tags: Environment=foo,Team=bar

alb.ingress.kubernetes.io/certificate-arn: "redacted"

alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}, {"HTTPS":443}]'

alb.ingress.kubernetes.io/actions.ssl-redirect: '{"Type": "redirect", "RedirectConfig": { "Protocol": "HTTPS", "Port": "443", "StatusCode": "HTTP_301"}}'

spec:

rules:

- host: domain.com

http:

paths:

- path: /*

backend:

serviceName: ssl-redirect

servicePort: use-annotation

- path: /*

backend:

serviceName: redacted

servicePort: 80

- host: www.domain.com

http:

paths:

- path: /*

backend:

serviceName: ssl-redirect

servicePort: use-annotation

- path: /*

backend:

serviceName: redacted

servicePort: 80

Thank you.
