排查了一下，比较奇怪。应该是apisix-ingress-controller不能解析DNS的问题导致的。但是其他非APISIX的pod是可以解析NDS的。
因为apisix-ingress-controller 没有拉起来，所以我用了apisix pod 检测
kubectl exec apisix-ccdc7d58d-rvgnt -n ingress-apisix nslookup
apisix-admin.ingress-apisix.svc.cluster.local
kubectl exec [POD] [COMMAND] is DEPRECATED and will be removed in a future
version. Use kubectl exec [POD] -- [COMMAND] instead.
Server: 169.254.20.10
Address: 169.254.20.10:53
** server can't find apisix-admin.ingress-apisix.svc.cluster.local: SERVFAIL
** server can't find apisix-admin.ingress-apisix.svc.cluster.local: SERVFAIL
我自己启了一个busybox做以下测试，可以得到apisix-gateway 的IIP地址
kubectl exec busybox nslookup apisix-admin.ingress-apisix.svc.cluster.local
kubectl exec [POD] [COMMAND] is DEPRECATED and will be removed in a future
version. Use kubectl exec [POD] -- [COMMAND] instead.
Server: 169.254.20.10
