Kubernetes部署Prometheus+Grafana监控简录

• 部署步骤较为简单，如下：

# 在k8s的master节点进行部署
cd /opt
git clone https://github.com/coreos/kube-prometheus.git
cd kube-prometheus/

# 需要搂出来所有的镜像信息，使用阿里云镜像服务做中转加速，镜像信息简单搂取脚本如下：
find . -name "*.yaml" -exec grep 'image: ' {} \;|awk '{print $NF}'|sort|uniq
find . -name "*.yaml" -exec grep 'quay.io' {} \;|awk '{print $NF}'|sort|uniq

# 替换镜像
find . -name "*.yaml" -exec sed -i 's|gcr.io/google_containers/metrics-server-amd64:v0.2.0|registry.cn-hangzhou.aliyuncs.com/vinc-auto/metrics-server-amd64:v0.2.0|g' {} \;

# 安装 prometheus-operator
kubectl apply -f manifests/setup

# 安装 promethes metric adapter
kubectl apply -f manifests/

# 查看运行状态
kubectl get pods -n monitoring
kubectl top pods -n monitoring

# 修改 ClusterIP 为 NodePort，固定 nodePort 为 32100
# 浏览器访问测试 http://192.168.199.101:32100/graph
kubectl edit svc prometheus-k8s -n monitoring

# 修改 ClusterIP 为 NodePort，固定 nodePort 为 32200
# 浏览器访问 http://192.168.199.101:32200，用户名密码均为 admin
kubectl edit svc grafana -n monitoring
