组件阐明

Component description

MetricServer：是kubernetes集群资源应用状况的聚合器，收集数据给kubernetes集群内应用，如 kubectl,hpa,scheduler等。

PrometheusOperator：是一个零碎监测和警报工具箱，用来存储监控数据。

NodeExporter：用于各node的要害度量指标状态数据。

KubeStateMetrics：收集kubernetes集群内资源对象数 据，制订告警规定。

Prometheus：采纳pull形式收集apiserver，scheduler，controller-manager，kubelet组件数 据，通过http协定传输。

Grafana：是可视化数据统计和监控平台。

MetricServer: It is an aggregator of the resource usage of the kubernetes cluster, collecting data for use in the kubernetes cluster, such as kubectl, hpa, scheduler, etc.

PrometheusOperator: is a system monitoring and alerting toolbox used to store monitoring data.

NodeExporter: Used for the key metric status data of each node.

KubeStateMetrics: Collect resource object data in the kubernetes cluster and formulate alarm rules.

Prometheus: collect data from apiserver, scheduler, controller-manager, and kubelet components in a pull mode, and transmit it through the http protocol.

Grafana: It is a platform for visual data statistics and monitoring.

配置Google上网环境下的docker，docker会去外网进行下载局部镜像

Configure docker in Google's Internet environment, docker will go to the external network to download part of the image

sudo mkdir -p /etc/systemd/system/docker.service.dsudo touch /etc/systemd/system/docker.service.d/proxy.conf

[root@k8s-master-node1 ~]# cat /etc/systemd/system/docker.service.d/proxy.conf[Service]Environment="HTTP_PROXY=http://192.168.1.6:7890/" Environment="HTTPS_PROXY=http://192.168.1.6:7890/" Environment="NO_PROXY=localhost,127.0.0.1,.example.com"

dockerd代理的批改比拟非凡，它实际上是改systemd的配置，因而须要重载systemd并重启dockerd能力失效。

The modification of the dockerd agent is quite special. It actually changes the configuration of systemd, so systemd needs to be reloaded and dockerd restarted to take effect.

sudo systemctl daemon-reloadsudo systemctl restart docker

批改 grafana-service.yaml 文件，应用 nodepode 形式拜访 grafana：

Modify the grafana-service.yaml file and use nodepode to access grafana:

[root@k8s-master-node1 ~/kube-prometheus/manifests]# cat grafana-service.yamlapiVersion: v1kind: Servicemetadata:  labels:    app.kubernetes.io/component: grafana    app.kubernetes.io/name: grafana    app.kubernetes.io/part-of: kube-prometheus    app.kubernetes.io/version: 8.1.3  name: grafana  namespace: monitoringspec:  type: NodePort  ports:  - name: http    port: 3000    targetPort: http    nodePort: 31100  selector:    app.kubernetes.io/component: grafana    app.kubernetes.io/name: grafana    app.kubernetes.io/part-of: kube-prometheus

批改 prometheus-service.yaml，改为 nodepode：

Modify prometheus-service.yaml to nodepode:

[root@k8s-master-node1 ~/kube-prometheus/manifests]# cat prometheus-service.yamlapiVersion: v1kind: Servicemetadata:  labels:    app.kubernetes.io/component: prometheus    app.kubernetes.io/name: prometheus    app.kubernetes.io/part-of: kube-prometheus    app.kubernetes.io/version: 2.30.0    prometheus: k8s  name: prometheus-k8s  namespace: monitoringspec:  type: NodePort  ports:  - name: web    port: 9090    targetPort: web    nodePort: 31200  - name: reloader-web    port: 8080    targetPort: reloader-web    nodePort: 31300  selector:    app: prometheus    app.kubernetes.io/component: prometheus    app.kubernetes.io/name: prometheus    app.kubernetes.io/part-of: kube-prometheus    prometheus: k8s  sessionAffinity: ClientIP

批改 alertmanager-service.yaml，改为 nodepode

Modify alertmanager-service.yaml to nodepode

[root@k8s-master-node1 ~/kube-prometheus/manifests]# cat alertmanager-service.yaml apiVersion: v1kind: Servicemetadata:  labels:    alertmanager: main    app.kubernetes.io/component: alert-router    app.kubernetes.io/name: alertmanager    app.kubernetes.io/part-of: kube-prometheus    app.kubernetes.io/version: 0.23.0  name: alertmanager-main  namespace: monitoringspec:  type: NodePort  ports:  - name: web    port: 9093    targetPort: web    nodePort: 31400  - name: reloader-web    port: 8080    targetPort: reloader-web    nodePort: 31500  selector:    alertmanager: main    app: alertmanager    app.kubernetes.io/component: alert-router    app.kubernetes.io/name: alertmanager    app.kubernetes.io/part-of: kube-prometheus  sessionAffinity: ClientIP[root@k8s-master-node1 ~/kube-prometheus/manifests]# 

创立名称空间和CRD

Create namespace and CRD

[root@k8s-master-node1 ~/kube-prometheus]# kubectl create -f /root/kube-prometheus/manifests/setupnamespace/monitoring createdcustomresourcedefinition.apiextensions.k8s.io/alertmanagerconfigs.monitoring.coreos.com createdcustomresourcedefinition.apiextensions.k8s.io/alertmanagers.monitoring.coreos.com createdcustomresourcedefinition.apiextensions.k8s.io/podmonitors.monitoring.coreos.com createdcustomresourcedefinition.apiextensions.k8s.io/probes.monitoring.coreos.com createdcustomresourcedefinition.apiextensions.k8s.io/prometheuses.monitoring.coreos.com createdcustomresourcedefinition.apiextensions.k8s.io/prometheusrules.monitoring.coreos.com createdcustomresourcedefinition.apiextensions.k8s.io/servicemonitors.monitoring.coreos.com createdcustomresourcedefinition.apiextensions.k8s.io/thanosrulers.monitoring.coreos.com createdclusterrole.rbac.authorization.k8s.io/prometheus-operator createdclusterrolebinding.rbac.authorization.k8s.io/prometheus-operator createddeployment.apps/prometheus-operator createdservice/prometheus-operator createdserviceaccount/prometheus-operator created

期待资源可用后，装置

After waiting for resources to be available, install

[root@k8s-master-node1 ~/kube-prometheus]# [root@k8s-master-node1 ~/kube-prometheus]# [root@k8s-master-node1 ~/kube-prometheus]# kubectl create -f /root/kube-prometheus/manifests/---略---[root@k8s-master-node1 ~/kube-prometheus]#
