1. 部署kube-ui环境
请参考 docker集群管理工具kubernetes初步搭建
2. 下载kube-ui镜像
# 目前好像docker.io上不支持下载。从国内的一个网站上下载
docker pull index.alauda.cn/googlecontainer/kube-ui:v5
# 然后把此image推到你的私有镜像地址
# 启动私有镜像容器
> docker run -d -p 5000:5000 --name siyou -v /data/docker/registry:/tmp/registry docker.io/registry
>docker tag 1270a664f530 1.1.1.100:5000/kube-ui
# 把1.1.1.100:5000/kube-ui推到 siyou
>docker push 1.1.1.100:5000/kube-ui
# 确认下镜像上传成功没，如果没有，后面的kube-ui会失败
> curl -X GET http://1.1.1.100:5000/v2/_catalog
{"repositories":["centos","kube-ui","memcached","mysql","nginx","pause","php"]}
3. 创建kube-ui namespace
# 创建kube-namespace.yaml，内容如下：
apiVersion: v1
kind: Namespace
metadata:
name: kube-system
# 创建namespace
> kubectl create -f kube-namespace.yaml
namespace "kube-system" created
> kubectl get namespace
NAME STATUS AGE
default Active 5d
kube-system Active 6m
4. 创建rc创建kube-ui-rc-src.yaml 文件
# kube-ui-rc
kind: Deployment
apiVersion: extensions/v1beta1
metadata:
labels:
app: kubernetes-dashboard
name: kubernetes-dashboard
namespace: kube-system
spec:
# 建立3个副本
replicas: 3
selector:
matchLabels:
app: kubernetes-dashboard
template:
metadata:
labels:
app: kubernetes-dashboard
spec:
containers:
- name: kubernetes-dashboard
# 填写自己私有镜像地址
image: 1.1.1.100:5000/kube-ui
imagePullPolicy: Always
ports:
- containerPort: 8080
protocol: TCP
args:
# Uncomment the following line to manually specify Kubernetes API server Host
# If not specified, Dashboard will attempt to auto discover the API server and connect
# to it. Uncomment only if the default does not work.
# - --apiserver-host=http://my-address:port
livenessProbe:
httpGet:
path: /
port: 8080
initialDelaySeconds: 30
timeoutSeconds: 30
# kube-ui-srv
---
kind: Service
apiVersion: v1
metadata:
labels:
app: kubernetes-dashboard
name: kubernetes-dashboard
namespace: kube-system
spec:
type: NodePort
ports:
- port: 80
targetPort: 8080
selector:
app: kubernetes-dashboard
- 配置参考：https://rawgit.com/kubernetes/dashboard/master/src/deploy/kubernetes-dashboard.yaml
# 运行一下命令创建rc和service,查看创建完成的pod（因设定了空间，查询时也要加上namespace，否则无法显示）：kubectl get pod --namespace=kube-system
> kubectl create -f kube-ui.yaml
# 运行以下命令创建service，并查看service 和 pods
> kubectl get pod,rc --all-namespaces -o wide
NAMESPACE NAME READY STATUS RESTARTS AGE NODE
kube-system kubernetes-dashboard-3943700943-endp7 1/1 Running 0 2m 1.1.1.101
kube-system kubernetes-dashboard-3943700943-o60eg 0/1 ContainerCreating 0 2m 1.1.1.102
kube-system kubernetes-dashboard-3943700943-rk3yy 1/1 Running 0 2m 1.1.1.101
# 可以看到kube-ui服务正在运行，有两个副本分配到 101上了，一个在102上，但状态为 ContainerCreating，我们分别去101和102上查看下：

NAME ENDPOINTS AGE
kubernetes-dashboard 10.1.37.2:8080,10.1.37.3:8080 19m
5. master配置flannel
# 配置flannel网络，与minion连通master安装flannel，并启动
>yum install flannel -y
>systemctl enable flanneld
>systemctl start flanneld
6. 访问kube-ui
# 访问 http://1.1.1.100:8080/ui/ 会自动跳转 http://1.1.1.100:8080/api/v1/proxy/namespaces/kube-system/services/kube-ui/#/dashboard/ 即可访问kube-ui的dashboard 页面，如下图所示：
kube-ui
可以查看minion的系统信息，pods，RC，services等信息
- 自此，kube-ui搭建成功，后续对其进行一些操作实战。。。
