好的，目前似乎不支持=〉https://github.com/kubernetes-sigs/aws-alb-ingress-controller/issues/835

添加操作注解：
alb.ingress.kubernetes.io/actions.redirect-home: {“类型”：“重定向”，“重定向配置”：{“主机”：“abc.example.com“，“路径”：“/我的上下文/其他路径”，“端口”：“443”，“协议”：“HTTPS”，“查询”：“#{查询}"，“状态代码”：“HTTP_301”}}'
向操作添加路由：

- backend:
          service:
            name: redirect-home
            port:
              name: use-annotation
        path: /some-path
        pathType: ImplementationSpecific

这会将/some-path重定向到abc.example.com/mycontext/other-path
谢谢

曾经我的需求是重定向从coffee.xyz.com到coffee.abc.com的流量，所以为此，我使用alb重定向注解。

alb.ingress.kubernetes.io/actions.coffee-redirection: '{"Type":"redirect","RedirectConfig":{"Host":"coffee.xyz.com","Port":"443","Protocol":"HTTPS","Query":"#{query}","StatusCode":"HTTP_301"}}'

以下是同一问题的完整代码块。
