解决coredns的health插件占用8080端口的问题(kubeasz)

[Valdanitooooo]

问题

本来端口就不够用，k8s还占了8080，导致有三台机器无法使用8080端口

解决办法

sudo su
cd /etc/kubeasz/clusters/default/yml/
kubectl delete -f nodelocaldns.yaml
vim nodelocaldns.yaml
搜索health，把相关内容注释
#health 169.254.20.10:8080
          #livenessProbe:
          #  httpGet:
          #    host: 169.254.20.10
          #    path: /health
          #    port: 8080
          #  initialDelaySeconds: 60
          #  timeoutSeconds: 5
kubectl apply -f nodelocaldns.yaml
lsof -i:8080
