Automation Scenarios

This section aims to provide the community with example automation scripts using the CLI IoT extension in order to jump start Azure IoT scenario ideas.

Delete IoT Edge deployments based on criteria

# List all deployments on target hub and filter on a target condition, then select the ID.
$deployments = az iot edge deployment list -n YourIoTHub --query "[?targetCondition=='tags.building=9'].id" | ConvertFrom-Json
 
# After getting the filtered deployments, iterate and delete
$deployments | ForEach-Object -process {az iot edge deployment delete -n YourIoTHub -d $_}
