在上一编文章[部署kubernetes][kubernetes]集群成功之后，接下来就是部署监控系统了，本编博客主要是基于coreos开源的prometheus-operator监控系统，该监控系统比较全面，主要是已经搞定了grafana的监控模版，废话不多说，接下来就进入正题:

下载[v0.16.0.tar.gz][] release版本的prometheus-operator,然后解压(也可以下载源码自行编译)

wget https://github.com/coreos/prometheus-operator/archive/v0.16.0.tar.gz
    tar -zvxf v0.16.0.tar.gz
    
    [root@master-27 prometheus]# ls -l
    total 5968
    drwxrwxr-x 13 root root    4096 Jan 12 21:41 prometheus-operator-0.16.0
    -rw-r--r--  1 root root    2068 Jun 20 19:37 prometheus.yaml
    -rwxr-xr-x  1 root root 6102555 Jun 20 20:03 v0.16.0.tar.gz

部署prometheus-operator的deployment

//用到的镜像是
     - --config-reloader-image=quay.io/coreos/configmap-reload:v0.0.1
            image: quay.io/coreos/prometheus-operator:v0.16.0
    
    kubectl create -f bundle.yaml

部署成功查看

[root@master-27 prometheus-operator-0.16.0]# kubectl get deployment 
    NAME                  DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE
    prometheus-operator   1         1         1            1           13h
    
    [root@master-27 prometheus-operator-0.16.0]# kubectl get pod 
    NAME                                   READY     STATUS    RESTARTS   AGE
    prometheus-operator-1084866340-sfpl3   1/1       Running   0          13h

部署grafana alternanager kube-status-meric

[root@master-27 prometheus-operator-0.16.0]# cd contrib/kube-prometheus/
    [root@master-27 kube-prometheus]# pwd
    /root/prometheus/prometheus-operator-0.16.0/contrib/kube-prometheus
    ./hack/cluster-monitoring/deploy
    
    [root@master-27 kube-prometheus]# ./hack/cluster-monitoring/deploy

用到的镜像好多,这里就不多说了，主要是有个镜像是谷歌的需要翻墙，可以自行翻墙下载，其他镜像都是`quay.io/coreos`，这个特别的镜像是

gcr.io/google_containers/addon-resizer:1.0

访问grafana的页面`master-ip:/30902`,

访问prometheus的页面`master-ip:/30900`  
![111][]

访问alertmanager 告警页面`master-ip:/30903`  
![1al][]  
到此为止，已经成功部署了k8s集群监控prometheus-operator
