安装Prometheus-Opeartor

一、下载
git clone clone https://github.com/coreos/prometheus-operator.git
或：
wget https://github.com/coreos/prometheus-operator/archive/v0.23.0.tar.gz并解压 （我用的是这种）

二、部署
1、官方推荐新建一个namespace，所有需要新建一个namespace

[^_^] linux02 ~# kubectl create namespace monitoring

[^_^] linux02 ~# kubectl get namespaces
NAME STATUS AGE
default Active 22d
kube-public Active 22d
kube-system Active 22d
monitoring Terminating 1h

2、修改配置文件：
进入文件 cd prometheus-operator-0.23.0

[^_^] linux02 prometheus-operator-0.23.0# vim bundle.yaml

#总共有三处namespace需要修改
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: prometheus-operator
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: prometheus-operator
subjects:
- kind: ServiceAccount
name: prometheus-operator
namespace: monitoring #第一处

---
apiVersion: apps/v1beta2
kind: Deployment
metadata:
labels:
k8s-app: prometheus-operator
name: prometheus-operator
namespace: monitoring #第二处

---
apiVersion: v1
kind: ServiceAccount
metadata:
name: prometheus-operator
namespace: monitoring #第三处

3、执行创建：
kubectl apply -f bundle.yaml

4、部署kube-prometheus
kubectl apply -f contrib/kube-prometheus/manifests/

5、查看
kubectl get all -n monitoring

6、为了方便访问 ，修改访问方式，供外部访问
修改service的访问方式为NodePort ,使用kubectl edit svc [svcname] -n monitoring方式修改
总共修改三个
alertmanager-main
grafana
prometheus-k8s

7、访问：https://47.94.3.211:31162
