[Kubernetes] DNS doesn't work - check DNS containers

by 스뎅(thDeng) on March 7, 2017

갑자기 kube-dns가 응답을 안 할 때, container가 모두 실행 중인지 체크해 보자.

Kubernetes DNS Pods and Services 문서에 따르면, Kubernetes의 DNS는 3개의 container로 나뉘어져 있다.:

• kubedns
• dnsmasq
• healthz

The running Kubernetes DNS pod holds 3 containers - kubedns, dnsmasq and a health check called healthz.
