镜像地址

qiuyin/raspberrypi-gas-sensor:dind
注意：镜像使用的架构为ARMv7,并且只能在raspberrypi上使用

使用

云端

1. 安装k8s

2. 安装kubeedge，参考资料kubeedge

3. 为边缘节点命名

   kubectl label nodes raspberrypi name=raspberrypi
   

4. 创建资源

   kubectl apply -f crds/model.yaml
   kubectl apply -f crds/instance.yaml
   kubectl create -f deployment.yaml
   

边缘端

1. 安装kubeedge，参考资料kubeedge

2. 安装mosquitto

   apt install mosquitto
   

云端查询数据

1. 使用命令行查询

   kubectl get device concentration -oyaml -w
   

2. 效果如下

    apiVersion: devices.kubeedge.io/v1alpha2
   
    kind: Device
    metadata:
    annotations:
        kubectl.kubernetes.io/last-applied-configuration: |
