Coredns自定义域名解析

修改coredns configmap

$ kubectl edit cm -n kube-system coredns

apiVersion: v1 data: Corefile: | .:53 { errors health { lameduck 5s } hosts { 192.168.99.181 k8s.lvzhenjiang.com fallthrough } ready kubernetes cluster.local in-addr.arpa ip6.arpa { pods insecure fallthrough in-addr.arpa ip6.arpa ttl 30 } prometheus :9153 forward . /etc/resolv.conf cache 30 loop reload loadbalance } kind: ConfigMap metadata: name: coredns namespace: kube-system

重启coredns服务后，进行测试！

$ k exec busybox-86dbf5b9d8-tx8j8 -- ping k8s.lvzhenjiang.com PING k8s.lvzhenjiang.com (192.168.99.181): 56 data bytes 64 bytes from 192.168.99.181: seq=0 ttl=63 time=0.536 ms 64 bytes from 192.168.99.181: seq=1 ttl=63 time=0.690 ms 64 bytes from 192.168.99.181: seq=2 ttl=63 time=2.023 ms 64 bytes from 192.168.99.181: seq=3 ttl=63 time=1.240 ms
