The scenario is like this
I have a microservice which invokes a LAMBDA function whose role will be to delete things from the AWS IOT.
Is there a way I can perform operations in AWS IOT using the lambda function?
Any article, blog regarding this will be a huge help as I'm not able to find any integration document on the web.
I found a way to do several operations in AWS IOT using lambda function by the means of API's.
The above link has description about API's which will help in this case. A sample lambda function script to delete a thing from the IOT is
import json
import boto3
def lambda_handler(event, context):
thing_name = event['thing_name']
delete_thing(thing_name=thing_name)
def delete_thing(thing_name):
c_iot = boto3.client('iot')
print(" DELETING {}".format(thing_name))
try:
r_principals = c_iot.list_thing_principals(thingName=thing_name)
except Exception as e:
print("ERROR listing thing principals: {}".format(e))
r_principals = {'principals': []}
print("r_principals: {}".format(r_principals))
for arn in r_principals['principals']:
cert_id = arn.split('/')[1]
print(" arn: {} cert_id: {}".format(arn, cert_id))
r_detach_thing = c_iot.detach_thing_principal(thingName=thing_name, principal=arn)
print("DETACH THING: {}".format(r_detach_thing))
r_upd_cert = c_iot.update_certificate(certificateId=cert_id, newStatus='INACTIVE')
print("INACTIVE: {}".format(r_upd_cert))
r_del_cert = c_iot.delete_certificate(certificateId=cert_id, forceDelete=True)
print(" DEL CERT: {}".format(r_del_cert))
r_del_thing = c_iot.delete_thing(thingName=thing_name)
print(" DELETE THING: {}\n".format(r_del_thing))
And the input for this lambda function will be
{
"thing_name": "MyIotThing"
}
