篇幅五. prometheus-operator安装
1. 下载包
1.1.1.1(可连公网服务器)
git clone -b v0.10.0 https://github.com/prometheus-operator/kube-prometheus.git
scp -r kube-prometheus root@1.1.1.5:/home/kubernetes/k8s/app
2. 配置修改
ll kube-prometheus| awk -F' ' '{print $9}'

我们需要修改的是 manifests 下所有 .yaml 里的 image 字段
把公网地址换成内网 私有仓库地址
./alertmanager-alertmanager.yaml: image: 1.1.1.1:5000/alertmanager:v0.23.0
./blackboxExporter-deployment.yaml: image: 1.1.1.1:5000/blackbox-exporter:v0.19.0

./kubeStateMetrics-deployment.yaml: image: 1.1.1.1:5000/kube-state-metrics:2.3.0

./prometheusOperator-deployment.yaml: - --prometheus-config-reloader=1.1.1.1:5000/prometheus-config-reloader:v0.53.1

./prometheus-prometheus.yaml: image: 1.1.1.1:5000/prometheus:v2.32.1
3. 安装
cd kube-prometheus
kubectl apply --server-side -f manifests/setup
kubectl create -f manifests/
此步骤执行完 大概率有部分pod 启动不了，原因是 manifests 下多了一些脚本生成的 yaml文件，
此些yaml文件里image 默认还是公网地址，根据 未启动pod 找到 对应yaml文件修改正确即可
修改正确后再次 apply
kubectl apply -f manifests/
4. 修改prometheus以及alertmanage的Service为NodePort
4. 1 cat manifests/prometheus-service.yaml
apiVersion: v1
kind: Service
metadata:
labels:
app.kubernetes.io/component: prometheus
app.kubernetes.io/instance: k8s
app.kubernetes.io/name: prometheus
app.kubernetes.io/part-of: kube-prometheus
app.kubernetes.io/version: 2.32.1
name: prometheus-k8s
namespace: monitoring
spec:
type: NodePort
ports:
- name: web
port: 9090
targetPort: web
nodePort: 9090
- name: reloader-web
port: 8080
targetPort: reloader-web
selector:
app.kubernetes.io/component: prometheus
app.kubernetes.io/instance: k8s
app.kubernetes.io/name: prometheus
app.kubernetes.io/part-of: kube-prometheus
sessionAffinity: ClientIP
4. 2 cat manifests/alertmanager-service.yaml
apiVersion: v1
kind: Service
metadata:
labels:
app.kubernetes.io/component: alert-router
app.kubernetes.io/instance: main
app.kubernetes.io/name: alertmanager
app.kubernetes.io/part-of: kube-prometheus
app.kubernetes.io/version: 0.23.0
name: alertmanager-main
namespace: monitoring
spec:
type: NodePort
ports:
- name: web
port: 9093
targetPort: web
nodePort: 9093
- name: reloader-web
port: 8080
targetPort: reloader-web
selector:
app.kubernetes.io/component: alert-router
app.kubernetes.io/instance: main
app.kubernetes.io/name: alertmanager
app.kubernetes.io/part-of: kube-prometheus
sessionAffinity: ClientIP
4. 3 再次apply
kubectl apply -f manifests/prometheus-service.yaml
kubectl apply -f manifests/alertmanager-service.yaml
这样web端即可访问 prometheus 以及 alertmanager
注: 此处 映射 9090 9093端口也是需要开启的，k8s默认好像只能用30000以上端口
修改配置文件/etc/kubernetes/manifests/kube-apiserver.yaml
#添加 - --service-node-port-range=1-65535 此行
- --service-cluster-ip-range=10.96.0.0/12
- --service-node-port-range=1-65535
- --tls-cert-file=/etc/kubernetes/pki/apiserver.crt
重启 kubectl
systemctl daemon-reload
systemctl restart kubelet
