Kubernetes部署Prometheus+Grafana監控簡錄

• 部署步驟較爲簡單，如下：

# 在k8s的master節點進行部署
cd /opt
git clone https://github.com/coreos/kube-prometheus.git
cd kube-prometheus/

# 需要摟出來所有的鏡像信息，使用阿里雲鏡像服務做中轉加速，鏡像信息簡單摟取腳本如下：
find . -name "*.yaml" -exec grep 'image: ' {} \;|awk '{print $NF}'|sort|uniq
find . -name "*.yaml" -exec grep 'quay.io' {} \;|awk '{print $NF}'|sort|uniq

# 替換鏡像
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' {} \;

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

# 安裝 promethes metric adapter
kubectl apply -f manifests/

# 查看運行狀態
kubectl get pods -n monitoring
kubectl top pods -n monitoring

# 修改 ClusterIP 爲 NodePort，固定 nodePort 爲 32100
# 瀏覽器訪問測試 http://192.168.199.101:32100/graph
kubectl edit svc prometheus-k8s -n monitoring

# 修改 ClusterIP 爲 NodePort，固定 nodePort 爲 32200
# 瀏覽器訪問 http://192.168.199.101:32200，用戶名密碼均爲 admin
kubectl edit svc grafana -n monitoring
