針對 K8s 環境內定義類似 /etc/hosts 方式

Resources → Config → Namespace: kube-system → coredns → Edit

Corefile 的內容改成類似以下:

.:53 {
    errors
    health {
      lameduck 5s
    }
    ready
    kubernetes cluster.local in-addr.arpa ip6.arpa {
      pods insecure
      fallthrough in-addr.arpa ip6.arpa
    }
    prometheus :9153
    forward . "/etc/resolv.conf"
    cache 30
    loop
    reload
    loadbalance
    hosts iiidevops.tw {
      192.168.7.101 www.iiidevops.tw
      192.168.7.101 gitlab.iiidevops.tw
      192.168.7.101 redmine.iiidevops.tw
      192.168.7.101 harbor.iiidevops.tw
      192.168.7.101 sonarqube.iiidevops.tw
      fallthrough
    }
}
