官方文档： https://kuboard.cn/learning/k8s-intermediate/service/network.html#%E6%95%B0%E6%8D%AE%E5%8C%85%E7%9A%84%E4%BC%A0%E9%80%92-pod-to-pod-%E8%B7%A8%E8%8A%82%E7%82%B9

获取yaml文件

kubectl apply -f https://kuboard.cn/install-script/kuboard.yaml
kubectl apply -f https://addons.kuboard.cn/metrics-server/0.3.7/metrics-server.yaml

获取Token

echo $(kubectl -n kube-system get secret $(kubectl -n kube-system get secret | grep kuboard-user | awk '{print $1}') -o go-template='{{.data.token}}' | base64 -d)

查看 Kuboard 运行状态

kubectl get pods -l k8s.kuboard.cn/name=kuboard -n kube-system -o wide
[root@test3 data]# kubectl get pods -l k8s.kuboard.cn/name=kuboard -n kube-system -o wide

搭建部署一个nginx服务

点击保存创建nginx的Deployments

NFS部署搭建

  [root@k8s-master01 ~]#  yum install -y nfs-utils
  [root@k8s-master01 ~]# vim /etc/exports

    /data/k8snfs  192.168.31.10(rw,sync,no_root_squash)
    /data/k8snfs  192.168.31.243(rw,sync,no_root_squash)
    /data/k8snfs  192.168.31.5(rw,sync,no_root_squash)
 [root@k8s-master01 ~]# systemctl  start nfs 
     [root@k8s-master01 ~]#   showmount  -e 192.168.31.10

 Export list for 192.168.31.10:
 /data/k8snfs 192.168.31.5,192.168.31.243,192.168.31.10

部署的nginx服务会自动生成一个NFS的pod

进入NFS查看目录生成

访问nginx服务

[root@k8s-master01 nginx]# kubectl get pod -n default -o wide #查看pod所在node和非配的Ip地址
[root@k8s-master01 nginx]# kubectl get service -n default -o wide #查看pod对应service的Ip地址和对应宿主机的端口

查看各个pod节点和service节点互通情况(calico)

[root@test3 ~]#  kubectl run curl --image=radial/busyboxplus:curl -i --tty
  [root@test1 ~]# kubectl  get service -n default
