How to invoke s3 create object event using sam-local

[shilpa-jindal]

I have written a Lambda function that uploads data from a file to Database when a new file is uploaded to S3.
I have the test file on my local folder.
How do i generate an S3 event which mimics file upload on s3 bucket by pointing to my local folder?
For example, i have "test.txt" file sitting in /usr/local/samlocal-files/ folder on my local.
So, how do i create S3 event in a way that
S3Object object = amazonS3.getObject(new GetObjectRequest(s3Bucket, s3Key)); is able to read file "/usr/local/samlocal-files/test.txt" ?

I can't tell from the docs if:

• this is not possible and we never said it was
• we can simulate a local s3 in this way
• we can proxy an actual s3 in this way

That would be very helpful

I have the same function and use minio to simulate the S3 locally

@danilopopeye Would you please mind providing us an example project with your workaround?

[danilopopeye]

@jkomyno have a look in this doc aws-sdk-for-javascript-with-minio. This is basically what I did.

sam local generate-event s3 is what you need. Give it a try

[suneelthakur1980]

Created event file
sam local generate-event s3 >>event.json using SAM 0.3.0

sam local invoke -e event.json

Resulting timeout error at
s3.getObject(params, (err, data) => {

Error
2018-06-21 16:44:00 Function 's3getobject' timed out after 15 seconds
What could be the issue?

This will generate an S3 object event. What we need is the ability to seed data into the "local S3 bucket resource" so it can be retrieved from the Lambda which is triggered by the event.

I was wondering if it is possible to simulate a S3 resource PUT and lambda-function fetching S3-object on trigger with sam local ?? Please let me know how can I do that ?

@avimehenwal I was looking for the same, Have you find any?
