1. 准备工作
参看CentOS7配置Kubernetes（K8S）集群 这里使用k8s版本为1.5.2
2. 准备yaml

Uncomment only if the default does not work. - --apiserver-host=192.168.0.51:8080 livenessProbe: httpGet: path: / port: 9090 initialDelaySeconds: 30 timeoutSeconds: 30 --- kind: Service apiVersion: v1 metadata: labels: app: kubernetes-dashboard name: kubernetes-dashboard namespace: kube-system spec: type: NodePort ports: - port: 80 targetPort: 9090 selector: app: kubernetes-dashboard
3. 启动
kubectl apply -f k8s-dashboard.yaml
4. 注意事项
4.1 kubelet
### # kubernetes kubelet (minion) config # The address for the info server to serve on (set to 0.0.0.0 or "" for all interfaces) KUBELET_ADDRESS="--address=0.0.0.0" # The port for the info server to serve on # KUBELET_PORT="--port=10250" # You may leave this blank to use the actual hostname KUBELET_HOSTNAME="--hostname-override=192.168.0.51" # location of the api-server KUBELET_API_SERVER="--api-servers=http://192.168.0.51:8080" # pod infrastructure container KUBELET_POD_INFRA_CONTAINER="--pod-infra-container-image=docker.io/openshift/origin-pod:latest" # Add your own! KUBELET_ARGS=""
将这里的ip地址修改为0.0.0.0和192.168.0.51(master地址)，这里将pod-infra指向本地镜像pod-infra-container-image=docker.io/openshift/origin-pod:latest，需要在master和slave端都配置一遍
4.2 apiserver
### # kubernetes system config # # The following values are used to configure the kube-apiserver # # The address on the local server to listen to. KUBE_API_ADDRESS="--insecure-bind-address=0.0.0.0" # The port on the local server to listen on. # KUBE_API_PORT="--port=8080" # Port minions listen on # KUBELET_PORT="--kubelet-port=10250" # Comma separated list of nodes in the etcd cluster KUBE_ETCD_SERVERS="--etcd-servers=http://192.168.0.51:2379" # Address range to use for services KUBE_SERVICE_ADDRESSES="--service-cluster-ip-range=10.254.0.0/16" # default admission control policies #KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ServiceAccount,ResourceQuota" KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ResourceQuota" # Add your own! KUBE_API_ARGS=""
这里去除账号验证
4.3 pod-infrastructure
安装Pod时需要用到这个镜像，提前准备，不然会因为GW的原因下不到

下载一个镜像
[root@k8s-master elk]# docker pull docker.io/openshift/origin-pod
同样的原因，提前准备dashboard的镜像

这里我选择第一个镜像
docker pull docker.io/mritd/kubernetes-dashboard-amd64
镜像准备，在master和slave端都进行准备
5. 进入界面
通过http://192.168.0.51:8080/ui进入页面，即主机ip和apiserver端口
