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

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
