基于Operator方式和二进制方式部署prometheus环境
基于Operator方式和二进制方式部署prometheus环境
Operator部署器是基于已经编写好的yaml文件，可以将prometheus server、alertmanager、grafana、nodeexporter等组件⼀键批量部署在k8s集群当中。
github项目地址：
根据支持的kubernetes版本去选择：
拉取项目代码
| root@master1:~\ git clone -b release-0.11 https://github.com/prometheus-operator/kube-prometheus.git |
替换谷歌仓库镜像为阿里云仓库
| root@master1:~\ cd kube-prometheus/ |
| root@master1:~/kube-prometheus\ grep "k8s.gcr.io" ./manifests/ -R #搜索要替换的谷歌仓库的镜像 |
| ./manifests/kubeStateMetrics-deployment.yaml: image: k8s.gcr.io/kube-state-metrics/kube-state-metrics:v2.5.0 |
| ./manifests/prometheusAdapter-deployment.yaml: image: k8s.gcr.io/prometheus-adapter/prometheus-adapter:v0.9.1 |
替换kube-state-metrics镜像为阿里云仓库镜像
| root@master1:~/kube-prometheus\ sed -i 's#k8s.gcr.io\/kube-state-metrics\/kube-state-metrics:v2.5.0#registry.cn-hangzhou.aliyuncs.com\/liangxiaohui\/kube-state-metrics:v2.5.0#g' ./manifests/kubeStateMetrics-deployment.yaml |
替换prometheus-adapter镜像为阿里云仓库镜像
| root@master1:~/kube-prometheus\ sed -i 's#k8s.gcr.io\/prometheus-adapter\/prometheus-adapter:v0.9.1#registry.cn-hangzhou.aliyuncs.com\/liangxiaohui\/prometheus-adapter:v0.9.1#g' ./manifests/prometheusAdapter-deployment.yaml |
删除prometheus相关组件的networkpolicy
因v0.11.0版本新增加了每个组件的网络策略，使用了目录下直接apply -f创建所有yaml，就需要手动删除
| root@master1:~/kube-prometheus/manifests\ mv *networkPolicy.yaml /tmp |
修改prometheus svc，通过nodeport访问prometheus server
| root@master1:~/kube-prometheus\# vim manifests/prometheus-service.yaml |

| app.kubernetes.io/name: prometheus |

修改grafana svc，通过nodeport访问grafana
| root@master1:~/kube-prometheus/manifests\# cat grafana-service.yaml |
| apiVersion: v1 |
| kind: Service |
| metadata: |
| labels: |
| app.kubernetes.io/component: grafana |

github项目官网部署参考：
使用server-side apply部署或者使用kubectl create -f部署
| root@master1:~/kube-prometheus\ kubectl apply --server-side -f manifests/setup |
server-side 官网参考：
https://kubernetes.io/zh-cn/docs/reference/using-api/server-side-apply/
服务器端应用协助用户、控制器通过声明式配置的方式管理他们的资源。 客户端可以发送完整描述的目标（A fully specified intent）， 声明式地创建和/或修改对象。...服务器端应用既是原有 kubectl apply的替代品， 也是控制器发布自身变化的一个简化机制。
再接着部署manifests目录下的资源应用
| root@master1:~/kube-prometheus\ kubectl apply -f manifests/ |
prometheus都部署在monitoring的ns下，查看pod运行状态
| root@master1:~/kube-prometheus\ kubectl get pods -n monitoring |

安装cadvisor
监控Pod指标数据需要使用cadvisor，cadvisor由谷歌开源，在kubernetes v1.11及之前的版本内置在kubelet中并监听在4194端口(https://github.com/kubernetes/kubernetes/pull/65707)，从v1.12开始kubelet中的cadvisor被移除，因此需要单独通过daemonset等方式部署。
cadvisor（容器顾问）不仅可以搜集⼀台机器上所有运行的容器信息，还提供基础查询界⾯和http接口，方便其他组件如Prometheus进行数据抓取，cAdvisor可以对节点机器上的容器进行实时监控和性能数据采集，包括容器的CPU使用情况、内存使用情况、网络吞吐量及文件系统使用情况。
docker部署cadvisor
cadvisor镜像准备：
