Grafana 连接 Mongo 数据源

Grafana 连接 Mongo 数据源

说明

默认Grafana 连接Mongo 数据源插件为企业版，需要付费。

通过以下方式可以绕过企业版，使用第三方插件连接Mongo

第三方插件地址：https://github.com/JamesOsgood/mongodb-grafana

流程

1. Grafana 插件目录下载第三方插件
2. Grafana 免签第三方插件
3. 将第三方插件打包为镜像
4. 将镜像使用deployment启动，制作代理服务
5. Grafana 中使用mongo 数据源，连接代理url连接至mongo

一、第三方插件下载

• 下载第三方插件，RENAME

bash-5.1$ cd /var/lib/grafana/plugins/
bash-5.1$ wget https://github.com/JamesOsgood/mongodb-grafana/archive/refs/heads/master.zip
bash-5.1$ unzip mongodb-grafana-master.zip && mv mongodb-grafana-master grafana-mongodb-datasource 

二、Grafana 免签第三方插件

• Grafana Deployment 增加变量
• 为什么开启免签：Grafana不信任第三方插件

    spec:
      containers:
      - env:
        - name: GF_PLUGINS_ALLOW_LOADING_UNSIGNED_PLUGINS
          value: grafana-mongodb-datasource

三、第三方插件打包为镜像

1. 下载第三方插件至本地

root@management:/b# wget https://github.com/JamesOsgood/mongodb-grafana/archive/refs/heads/master.zip
root@management:/b# unzip mongodb-grafana-master.zip

2. 制作Dockerfile

root@management:/b# cat Dockerfile 
FROM node:14
COPY mongodb-grafana-master /app
WORKDIR /app
RUN npm install 
ENTRYPOINT ["npm","run","server"]

3. BUILD

docker build -t ppio-harbor-registry.tencentcloudcr.com/developer/grafana-mongodb-plugin:v1 .

四、镜像使用Deployment /SVC启动

1. Deployment

root@management:/opt/k8s-dev-tieta/grafana# cat grafana-mongodb-plugin-proxy-deployment.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: grafana-mongo-plugin
  namespace: monitoring
spec:
  replicas: 1
  selector:
    matchLabels:
      app.kubernetes.io/component: grafana-mongo-plugin
      app.kubernetes.io/name: grafana-mongo-plugin
  template:
    metadata:
      labels:
        app.kubernetes.io/component: grafana-mongo-plugin
        app.kubernetes.io/name: grafana-mongo-plugin
    spec:
      containers:
      - image: ppio-harbor-registry.tencentcloudcr.com/developer/grafana-mongodb-plugin:v1 
        name: grafana-mongo-plugin
        ports:
        - containerPort: 3333
          name: http
        resources:
          limits:
            cpu: 1000m
            memory: 2000Mi
          requests:
            cpu: 50m
            memory: 100Mi               

2. Service

root@management:/opt/k8s-dev-tieta/grafana# cat grafana-mongodb-plugin-proxy-service.yaml 
apiVersion: v1
kind: Service
metadata:
  labels:
    app.kubernetes.io/component: grafana-mongo-plugin
    app.kubernetes.io/name: grafana-mongo-plugin
  name: grafana-mongo-plugin
  namespace: monitoring
spec:
  ports:
  - name: http
    port: 3333
    targetPort: 3333
  selector:
    app.kubernetes.io/component: grafana-mongo-plugin
    app.kubernetes.io/name: grafana-mongo-plugin
