注:
   new-----初始化集群安装时使用该选项；
   existing-----新加入集群时使用该选项。

C.启动 etcd

1 2 3

# systemctl start etcd # systemctl status etcd # systemctl enable etcd

##查看集群成员

1 2	# etcdctl member list b0f5befc15246c67: name=etcd peerURLs=http://192.168.100.104:2380 clientURLs=http://192.168.100.104:2379 isLeader=true

--cluster-dns=10.254.0.2  
--cluster-domain=cluster.local.
                  ##与 KubeDNS Pod 配置的参数一致

H. 查看集群信息

1 2	# kubectl cluster-info Kubernetes master is running at http://localhost:8080

10. 部署 KubeDNS 插件
官方的yaml文件目录：kubernetes/cluster/addons/dns。
https://github.com/kubernetes/ku ... /cluster/addons/dns

1	# mkdir dns && cd dns

##下载 Kube-DNS 相关 yaml 文件

1	# curl -O https://raw.githubusercontent.co ... /kube-dns.yaml.base

##修改后缀

1	# cp kube-dns.yaml.base kube-dns.yaml

### 替换所有的 images

1	# sed -i 's/gcr.io\/google_containers/192.168.100.100\/k8s/g' kube-dns.yaml

####替换如下

1 2	# sed -i "s/__PILLAR__DNS__SERVER__/10.254.0.2/g" kube-dns.yaml # sed -i "s/__PILLAR__DNS__DOMAIN__/cluster.local/g" kube-dns.yaml

######对比

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

注1:这里我用的镜像是自己搭建的镜像仓库来pull，写这篇博文时kube-dns更新到了1.14.6，开会，墙又高了许多，所以拉取困难，我用回了1.14.5的版本，这里自行更改，自己能科学上网拉取最新版当然更好。
注2:看对比，第二个不同，1.14.6版--probe最后是SRV，而1.14.5版最后是A，这儿也要更改，不然会产生 CrashLoopBackOff 错误。
注3:这里我们要使用--kube-master-url命令指定apiserver，不然也会产生 CrashLoopBackOff 错误。
注4: 我将镜像放在了网易蜂巢上，地址:
     hub.c.163.com/zhijiansd/k8s-dns-kube-dns-amd64:1.14.5
          hub.c.163.com/zhijiansd/k8s-dns-dnsmasq-nanny-amd64:1.14.5
          hub.c.163.com/zhijiansd/k8s-dns-sidecar-amd64:1.14.5

### 执行该文件

1 2 3 4 5

# kubectl create -f kube-dns.yaml service "kube-dns" created serviceaccount "kube-dns" created configmap "kube-dns" created deployment "kube-dns" created

### 查看 KubeDNS 服务

11. 部署 Heapster 组件
###下载 heapster

1 2 3 4 5 6 7

# wget https://codeload.github.com/kube ... ar.gz/v1.5.0-beta.0 -O heapster-1.5.0-beta.tar.gz # tar -zxvf heapster-1.5.0-beta.tar.gz # cd heapster-1.5.0-beta.0/deploy/kube-config # cp rbac/heapster-rbac.yaml influxdb/ # cd influxdb/ # ls grafana.yaml  heapster-rbac.yaml  heapster.yaml  influxdb.yaml

###替换所有 images

1	# sed -i 's/gcr.io\/google_containers/192.168.100.100\/k8s/g' *.yaml

注:这里我也将镜像放在了网易蜂巢上，请自行更改:
      hub.c.163.com/zhijiansd/heapster-grafana-amd64:v4.4.3
            hub.c.163.com/zhijiansd/heapster-amd64:v1.4.0
            hub.c.163.com/zhijiansd/heapster-influxdb-amd64:v1.3.3

###更改 heapster.yaml

# grep source heapster.yaml        # - --source=kubernetes:https://kubernetes.default         - --source=kubernetes:http://192.168.100.104:8080?inClusterConfig=false

注: heapster 默认使用 https 连接 apiserver ，这里更改为使用 http 连接。


###执行 influxdb 目录下的所有文件

1 2 3 4 5 6 7 8 9

###查看集群信息

# kubectl cluster-info Kubernetes master is running at http://localhost:8080 Heapster is running at http://localhost:8080/api/v1/namespaces/kube-system/services/heapster/proxy KubeDNS is running at http://localhost:8080/api/v1/namespaces/kube-system/services/kube-dns/proxy monitoring-grafana is running at http://localhost:8080/api/v1/namespaces/kube-system/services/monitoring-grafana/proxy monitoring-influxdb is running at http://localhost:8080/api/v1/namespaces/kube-system/services/monitoring-influxdb/proxy

12. 部署 Kubernetes Dashboard
这里我们使用不需要证书的版本：

1	# curl -O https://raw.githubusercontent.co ... etes-dashboard.yaml

### 替换 images

1	# sed -i 's/gcr.io\/google_containers/192.168.100.100\/k8s/g' kubernetes-dashboard.yaml

注:请自行更改镜像地址:
     hub.c.163.com/zhijiansd/kubernetes-dashboard-amd64:v1.7.1


###添加 apiserver 地址

1 2 3

# grep apiserver kubernetes-dashboard.yaml           # - --apiserver-host=http://my-address:port            - --apiserver-host=http://192.168.100.104:8080

###执行该文件

1 2 3 4 5 6

# kubectl create -f kubernetes-dashboard.yaml serviceaccount "kubernetes-dashboard" configured role "kubernetes-dashboard-minimal" configured rolebinding "kubernetes-dashboard-minimal" configured deployment "kubernetes-dashboard" configured service "kubernetes-dashboard" configured

###检查 kubernetes-dashboard 服务

1 2	# kubectl get pods -n kube-system | grep dash kubernetes-dashboard-7648996855-54x6l   1/1       Running   1          7h

注:1.7版不能使用 kubectl cluster-info 查看到 kubernetes-dashboard 地址，1.6.3版的可以。

1.7.0版需要使用http://localhost:8080/api/v1/namespaces/kube-system/services/http:kubernetes-dashboard:/proxy/ 进行访问。而1.7.1版可以使用http://localhost:8080/api/v1/namespaces/kube-system/services/http:kubernetes-dashboard:/proxy/ 访问，也可以使用http://localhost:8080/ui访问，其会自动跳转。

13.查看 kubernetes dashboard
使用http://localhost:8080/ui访问

查看Pod界面



14. 查看 grafana
使用http://localhost:8080/api/v1/namespaces/kube-system/services/monitoring-grafana/proxy访问
