boto3 start/stop RDS instance with AWS Lambda

Question

While trying to start and stop RDS instances with boto3 on AWS Lambda, I am getting an interesting error - 'RDS' object has no attribute 'stop_db_instance': AttributeError

Even the simplest code throws this error, e.g.

import boto3

def lambda_handler(event, context):    
    boto3.client('rds').stop_db_instance(DBInstanceIdentifier='myInstanceID')

I am using python3.6 runtime, so as per information available on this page, boto3 1.4.4 should be available (which I assume already has proper methods - https://boto3.readthedocs.io/en/latest/reference/services/rds.html#RDS.Client.stop_db_instance)

Any suggestions are appreciates!

Answer 1

I was using boto3==1.4.1 and botocore==1.4.64 and receving same error as yours both locally and on lambda.

AWS Lambda must be using old botocore library. I tried using boto3==1.4.4 and botocore==1.5.75and it worked.

Therefore, decided to upload my own zip containing latest boto3 and botocore(mentioned above) and it works.

Creating a Deployment Package

UPDATE

Here is my aws lambda code snippet -

 import botocore
 import boto3

 def lambda_handler(event, context):
    print("Version is {}".format(botocore.__version__))
    boto3.client('rds').stop_db_instance(DBInstanceIdentifier='myInstanceID')

output: Version is 1.5.52

and 1.5.52 is responsible for not having stop_db_instance attribute in rds module. So, manually creating zip having the latest version will do the trick .

Thanks
