自定义域名如何加入到全局k8s环境dns解析

rysinal

尝试在coredns加入了自定义域hosts，但是重启coredns后不生效：

apiVersion: v1
data:
  Corefile: |
    .:53 {
        errors
        health
        ready
        kubernetes cluster.local in-addr.arpa ip6.arpa {
          pods insecure
          upstream /etc/resolv.conf
          fallthrough in-addr.arpa ip6.arpa
        }

        hosts {
          172.23.108.52 ks.env.info
          fallthrough
        }

        prometheus :9153
        forward . /etc/resolv.conf {
          prefer_udp
        }
        cache 30
        loop
        reload
        loadbalance
    }
