prometheus-operator来安装整套prometheus
官方所推荐的
https://github.com/prometheus-operator/kube-prometheus
开始安装
安装包和离线镜像包下载
https://cloud.189.cn/t/bM7f2aANnMVb (访问码:0nsj)
1. 解压下载的代码包
unzip kube-prometheus-master.zip
rm -f kube-prometheus-master.zip && cd kube-prometheus-master
2. 这里建议先看下有哪些镜像，便于在下载镜像快的节点上先收集好所有需要的离线docker镜像
# find ./ -type f |xargs grep 'image: '|sort|uniq|awk '{print $3}'|grep ^[a-zA-Z]|grep -Evw 'error|kubeRbacProxy'|sort -rn|uniq
quay.io/prometheus/prometheus:v2.22.1
quay.io/prometheus-operator/prometheus-operator:v0.43.2
quay.io/prometheus/node-exporter:v1.0.1
quay.io/prometheus/alertmanager:v0.21.0
quay.io/fabxc/prometheus_demo_service
quay.io/coreos/kube-state-metrics:v1.9.7
quay.io/brancz/kube-rbac-proxy:v0.8.0
grafana/grafana:7.3.4
gcr.io/google_containers/metrics-server-amd64:v0.2.01
directxman12/k8s-prometheus-adapter:v0.8.2
在测试的几个node上把这些离线镜像包都导入 docker load -i xxx.tar
3. 开始创建所有服务
kubectl create -f manifests/setup
kubectl create -f manifests/
过一会查看创建结果：
访问下prometheus的UI
修改下prometheus UI的service模式，便于我们访问
kubectl -n monitoring patch svc prometheus-k8s -p '{"spec":{"type":"NodePort"}}'
service/prometheus-k8s patched
kubectl -n monitoring get svc prometheus-k8s
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
prometheus-k8s NodePort 10.68.23.79 <none> 9090:22129/TCP 7m43s
点击上方菜单栏Status --- Targets ，我们发现kube-controller-manager和kube-scheduler未发现
monitoring/kube-controller-manager/0 (0/0 up)
monitoring/kube-scheduler/0 (0/0 up)
kubectl -n monitoring get all
# 附：清空上面部署的prometheus所有服务：
kubectl delete --ignore-not-found=true -f manifests/ -f manifests/setup
