原因分析:
一开始怀疑coredns原因
data:
Corefile: |
.:53 {
errors
health
kubernetes cluster.local in-addr.arpa ip6.arpa {
pods insecure
upstream
fallthrough in-addr.arpa ip6.arpa
}
prometheus :9153
proxy . 10.221.8.67
cache 30
loop
reload
loadbalance
}
ume.choerodon:53 {
errors
cache 30
proxy . 10.221.8.67
}
但是在此基础上创建了一个pod发现在pod中可以ping通域名
