Prepare

kind needs to pull the image from the Docker Hub. If there is a firewall accessing it through your network, you need to configure a proxy for your bash your-ip requires the use of an internal network address, cannot use localhost or 127.0.0.1

# export http_proxy="http://your-ip:port"
# export https_proxy="http://your-ip:port"
# export all_proxy="socks5://your-ip:port"
# export no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"

install kind and create cluster

go install sigs.k8s.io/kind@v0.22.0
kind create cluster

load all images to docker 🪞

make buildx-build-driver-image
make kind-load-images

Install TDEngine

run tdengine docker container 🏃‍♂️

docker run -d -p 6030:6030 -p 6041:6041 -p 6043-6049:6043-6049 -p 6043-6049:6043-6049/udp --name tdengine tdengine/tdengine:3.0.1.4

make sure it is running:

docker ps| grep tdengine

8dc20c5ea43b   tdengine/tdengine:3.0.1.4                        "/tini -- /usr/bin/e…"   About a minute ago   Up About a minute   0.0.0.0:6030->6030/tcp, 0.0.0.0:6041->6041/tcp, 0.0.0.0:6043-6049->6043-6049/tcp, 0.0.0.0:6043-6049->6043-6049/udp   tdengine

go into tedngine and init table 🚪

docker exec -it tdengine taos

Init TDEngine and Insert a default Data 🕹

Create database shifu;
Use shifu;
Create TABLE Temperature (ts TIMESTAMP, v FLOAT);
Create TABLE Humidity (ts TIMESTAMP, v FLOAT);
SHOW TABLES;
exit

🎉🎉 Congratulations on your successful installation of TDEngine! 👁️

Install Shifu

you just need to use one command to install Shifu 😋

kubectl apply -f shifu_install.yml

Run Shifu TelemetryService

First, you need to modify devicedeploy/http-deviceshifu-telemetryservice.yaml, and change the value of spec/serviceSettings/SQLSetting/serverAddress.

--- #telemetry_service.yaml
apiVersion: shifu.edgenesis.io/v1alpha1
kind: TelemetryService
metadata:
  name: push-endpoint-1
  namespace: devices
spec:
  telemetrySeriveEndpoint: http://telemetryservice.shifu-service.svc.cluster.local
  serviceSettings:
    SQLSetting:
      serverAddress: [YOUR_IP]:6041 # edit it to your your IP
      username: root
      secret: taosdata
      dbName: shifu
      dbTable: Temperature
      dbtype: TDengine
---
apiVersion: shifu.edgenesis.io/v1alpha1
kind: TelemetryService
metadata:
  name: push-endpoint-2
  namespace: devices
spec:
  telemetrySeriveEndpoint: http://telemetryservice.shifu-service.svc.cluster.local
  serviceSettings:
    SQLSetting:
      serverAddress: [YOUR_IP]:6041 # edit it to your your IP
      username: root
      secret: taosdata
      dbName: shifu
      dbTable: Humidity
      dbtype: TDengine

You can also change the dbTable to your table name in your TDEngine database, and of course you can change everything to what you want under SQLSetting. 🤗

Then, you can use the following command to install the telemetry service into your Kind cluster.

kubectl apply -f telemetryservicedeploy

🚀 Congratulations on your successful installation of Shifu's Telemetry Service! Following is the last step you need to do. 👍

Run deviceShifu to Connect to Temperature and humidity meter

🐎 One-liner:

kubectl apply -f devicedeploy

By default, the tdengine's secret which store the username and password in the file http-deviceshifu-secret.yaml If you want to create secret by yourself, you can use following command to create

kubectl create secret  generic taosdata --from-literal=username="root" --from-literal=password="taosdata" -n devices

Enjoy the results of your work🕹

You can use the following command to access the TDEngine docker container.

docker exec -it tdengine taos

Use the following SQL command to display the data you have collected.

use shifu;
Select * From Temperature;
Select * From Humidity;

You should see something like this:

t is the current temperature reading, and h is the current humidity reading.

😘 Thank you for experimenting all the demos. Have fun today!

Clean up

kubectl delete -f devicedeploy && kubectl delete -f telemetryservicedeploy
docker stop tdengine
