apply target condition to an edge device

[soheilade]

after deploying sample-deployment.yaml, kubectl get pods returns

NAME                                       READY   STATUS    RESTARTS   AGE
tempsensor-5bc6db6876-bw7sg                0/1     Running   0          15m

i wonder why the READY is 0/1?

here is the outcome of kubectl describe pod tempsensor

Also my IOTedge deployments are not applied to any of my IoTedge devices.

is my IoTEdgedevice missing the target condition? how to set this target condition on the device?

@soheilade That is correct. See step 2 in this lab for an example on how to set this from the az CLI: https://github.com/veyalla/el1#add-an-iot-edge-device-in-iot-hub

 az iot hub device-twin update --device-id replace-with-deviceid --hub-name replace-with-hubname --set tags='{"building":"b43"}'

It can be done from the IoT Hub portal as well:

This lab has a more detailed walkthru, but I've not updated it for a while: https://github.com/veyalla/iot-edge-custom-vision-kubernetes-lab

@veyalla , thanks, indeed useful.
