How do I use boto3 to simulate the Add Event Source
action on the AWS GUI Console in the Event Sources
tab.
I want to programatically create a trigger such that if an object is created in MyBucket
, it will call MyLambda
function(qualified with an alias).
The relevant api call that I see in the Boto3 documentation is create_event_source_mapping
but it states explicitly that it is only for AWS Pull Model while I think that S3 belongs to the Push Model. Anyways, I tried using it but it didn't work.
Scenarios:
I was looking at the wrong side. This is configured on S3
s3 = boto3.resource('s3')
bucket_name = 'mybucket'
bucket_notification = s3.BucketNotification(bucket_name)
response = bucket_notification.put(
NotificationConfiguration={'LambdaFunctionConfigurations': [
{
'LambdaFunctionArn': 'arn:aws:lambda:us-east-1:033333333:function:mylambda:staging',
'Events': [
's3:ObjectCreated:*'
],
},
]})
