k8s部署nginx集群

环境：

两台虚拟机，

10.10.20.203 部署docker、etcd、flannel、kube-apiserver、kube-controller-manager、kube-scheduler

10.10.20.206 部署docker、flannel、kubelet、kube-proxy

1、创建nginx-rc.yaml

apiVersion: v1

kind: ReplicationController

metadata:

  name: nginx-controller

spec:

  replicas:

  selector:

    name: nginx

  template:

    metadata:

      labels:

        name: nginx

    spec:

      containers:

        - name: nginx

          image: nginx

          ports:

            - containerPort:

2、创建nginx-service-nodeport.yaml

apiVersion: v1

kind: Service

metadata:

  name: nginx-service-nodeport

spec:

  ports:

    - port:

      targetPort:

      protocol: TCP

  type: NodePort

  selector:

    name: nginx

3、创建pod

kubectl create -f nginx-rc.yaml

4、创建service

kubectl create -f nginx-service-nodeport.yaml

5、查看pod

[root@k8s-master ~]# kubectl get pods

NAME                     READY     STATUS    RESTARTS   AGE

nginx-controller-v40nj   /       Running             1h

nginx-controller-zxdzh   /       Running             1h

[root@k8s-master ~]# kubectl describe pod nginx-controller-v40nj

Name:        nginx-controller-v40nj

Namespace:    default

Node:        k8s-slave1-/60.19.29.21

Start Time:    Thu,  Aug  :: -

Labels:        name=nginx

Status:        Running

IP:        10.0.83.3

Controllers:    ReplicationController/nginx-controller

Containers:

  nginx:

    Container ID:        docker://269adc9b693aba0356ba18e4253c2b498fc7b7a8ce0af83857fcfd6b70e6ef03

    Image:            nginx

    Image ID:            docker://sha256:0d409d33b27e47423b049f7f863faa08655a8c901749c2b25b93ca67d01a470d

    Port:            /TCP

    State:            Running

      Started:            Thu,  Aug  :: -

    Last State:            Terminated

      Reason:            Completed

      Exit Code:

      Started:            Thu,  Aug  :: -

      Finished:            Thu,  Aug  :: -

    Ready:            True

    Restart Count:

    Environment Variables:    <none>

Conditions:

  Type        Status

  Initialized     True

  Ready     True

  PodScheduled     True

No volumes.

QoS Tier:    BestEffort

Events:

  FirstSeen    LastSeen    Count    From                SubobjectPath        Type        Reason    Message

  ---------    --------    -----    ----                -------------        --------    ------    -------

  5m        5m            {kubelet k8s-slave1-}    spec.containers{nginx}    Normal        Pulling    pulling image "nginx"

  5m        5m            {kubelet k8s-slave1-}                Warning        MissingClusterDNS    kubelet does not have ClusterDNS IP configured and cannot create Pod using "ClusterFirst" policy. Falling back to DNSDefault policy.

  5m        5m            {kubelet k8s-slave1-}    spec.containers{nginx}    Normal        Pulled    Successfully pulled image "nginx"

  5m        5m            {kubelet k8s-slave1-}    spec.containers{nginx}    Normal        Created    Created container with docker id 269adc9b693a

6、查看service

[root@k8s-master ~]# kubectl get service

NAME                     CLUSTER-IP     EXTERNAL-IP   PORT(S)    AGE

kubernetes               10.254.0.1     <none>        /TCP    16h

nginx-service-nodeport   10.254.29.72   <nodes>       /TCP   49m

[root@k8s-master ~]# kubectl describe service nginx-service-nodeport

Name:            nginx-service-nodeport

Namespace:        default

Labels:            <none>

Selector:        name=nginx

Type:            NodePort

IP:            10.254.29.72

Port:            <unset>    /TCP

NodePort:        <unset>    /TCP

Endpoints:        10.0.83.2:,10.0.83.3:

Session Affinity:    None

No events.

7、测试service是否好用

因为service使用的是NodePort方式，所以在任何一个节点访问31152这个端口都可以访问nginx

$ curl 10.10.20.203:

<!DOCTYPE html>

<html>

<head>

<title>Welcome to nginx!</title>

<style>

    body {

        width: 35em;

        margin:  auto;

    }
