第七章完成kubernetes集群部署并验证

在其中一运算个节点上操作就行

创建nginx资源配置清单的yaml文件

[root@hdss7-21 ~]# vim /opt/kubernetes/conf/nginx-ds.yaml

apiVersion: extensions/v1beta1

kind: DaemonSet

metadata:

    name: nginx-ds

spec:

    template:

      metadata:

        labels:

          app: nginx-ds

      spec:

        containers:

        - name: my-nginx

          image: harbor.od.com/public/nginx:v1.7.9

          ports:

          - containerPort: 80

创建nginx资源

[root@hdss7-21 ~]# kubectl create -f  /opt/kubernetes/conf/nginx-ds.yaml

daemonset.extensions/nginx-ds created

查看pod

[root@hdss7-21 ~]# kubectl get pods

NAME             READY   STATUS    RESTARTS   AGE

nginx-ds-4ln28   1/1     Running   0          38s

nginx-ds-spdgm   1/1     Running   0          38s

[root@hdss7-21 ~]#  kubectl get pods -owide

NAME             READY   STATUS    RESTARTS   AGE   IP           NODE                NOMINATED NODE   READINESS GATES

nginx-ds-4ln28   1/1     Running   0          56s   172.7.22.2   hdss7-22.host.com   <none>           <none>

nginx-ds-spdgm   1/1     Running   0          56s   172.7.21.2   hdss7-21.host.com   <none>           <none>

在21主机上和22主机上只能访问自己创建的容器主机

例如，在21上访问172.7.21.2可以正常访问

[root@hdss7-21 ~]# curl 172.7.21.2

<!DOCTYPE html>

<html>

<head>

<title>Welcome to nginx!</title>

<style>

    body {

        width: 35em;

        margin: 0 auto;

        font-family: Tahoma, Verdana, Arial, sans-serif;

    }

</style>

</head>

<body>

<h1>Welcome to nginx!</h1>

<p>If you see this page, the nginx web server is successfully installed and

working. Further configuration is required.</p>

<p>For online documentation and support please refer to

<a href="http://nginx.org/">nginx.org</a>.<br/>

Commercial support is available at

<a href="http://nginx.com/">nginx.com</a>.</p>

<p><em>Thank you for using nginx.</em></p>

</body>

</html>

访问172.7.22.2（宿主机在10.4.7.22上）却无法连接

[root@hdss7-21 ~]# curl 172.7.22.2

^C

原因是我们利用docker跨宿主机还不能通信，后面介绍的flannel可以解决跨主机通信问题
