部署prometheus 监控k8s集群

目录

1、主机清单

2、拉取镜像

3、服务安装

4、安装prometheus-operator

5、查看custom metrics api

 6、获取prometheus端口

7、将 alertmanager-main 、grafana、prometheus-k8s的端口暴露出来

8、再次查看prometheus端口

9、浏览器访问IP：31940

部署k8集群参考使用kubeadm方式部署集群-CSDN博客

1、主机清单

2、拉取镜像

在k8s中部署prometheus所需的镜像已打包上传

prometheus-operator下载地址

prometheus-镜像下载地址

prometheus-包下载

docker pull quay.io/prometheus/alertmanager:v0.21.0
docker pull quay.io/prometheus/blackbox-exporter:v0.18.0
docker pull jimmidyson/configmap-reload:v0.5.0
docker pull quay.io/brancz/kube-rbac-proxy:v0.9.0
docker pull grafana/grafana:7.5.4
docker pull k8s.gcr.io/kube-state-metrics/kube-state-metrics:v2.1.1
docker pull quay.io/prometheus/node-exporter:v1.1.2
docker pull k8s.gcr.io/prometheus-adapter/prometheus-adapter:v0.9.0
docker pull quay.io/prometheus/prometheus:v2.26.0
docker pull quay.io/prometheus-operator/prometheus-operator:v0.47.0

3、服务安装

[root@k8s-master ~]# wget https://codeload.github.com/prometheus-operator/kube-prometheus/tar.gz/refs/tags/v0.9.0
[root@k8s-master ~]# tar xf v0.9.0
[root@k8s-master ~]# cd kube-prometheus-0.9.0/manifests

4、安装prometheus-operator

[root@k8s-master ~]# kubectl apply -f setup/
[root@k8s-master ~]# kubectl get pods -n monitoring # 查看pod全部RUNNING之后再执行后面指令
[root@k8s-master ~]# kubectl apply -f . 
[root@k8s-master ~]# kubectl get pods -n monitoring # 等待podRUNNING

5、查看custom metrics api

[root@k8s-master ~]# kubectl get apiservices -n monitoring | grep metrics
v1beta1.metrics.k8s.io                 monitoring/prometheus-adapter   True        3h52m

 6、获取prometheus端口

7、将 alertmanager-main 、grafana、prometheus-k8s的端口暴露出来

[root@kube-master manifests]# kubectl edit svc -n monitoring alertmanager-main

 同样的方法将grafana、prometheus-k8s也修改

8、再次查看prometheus端口

端口已暴露

9、浏览器访问IP：31940

 导入监控模板
