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

spec:
    rules:
        - host: "www.sejoung.com"
          http:
              paths:
                  - pathType: ImplementationSpecific
                    path: /*
                    backend:
                        service:
                            name: ssl-redirect
                            port:
                                name: use-annotation
                  - pathType: ImplementationSpecific
                    path: /*
                    backend:
                        service:
                            name: "sejoung-develop"
                            port:
                                number: 8080

alb.ingress.kubernetes.io/listen-ports 설정에 [{"HTTP": 80}, {"HTTPS": 443}] 2개 포트를 열어야 됨

alb.ingress.kubernetes.io/certificate-arn 설정이 되어 있어야 됨

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

최종적으로 제일 처음위치에 아래의 설정이 필요하다

- pathType: ImplementationSpecific
  path: /*
  backend:
      service:
          name: ssl-redirect
          port:
              name: use-annotation
