Some services publish these events to Lambda by invoking the cloud function directly (for example, Amazon S3). Lambda can also poll resources in other services that do not publish events to Lambda.
The solution can be hosted on an EC2 instance or in a lambda function. To read a file from a S3 bucket, the bucket name, object name needs to be known and the role associated with EC2 or lambda needs to have read permission to the bucket. A role needs to be setup using lambda and then adding S3 for the role. Welcome to the AWS Lambda tutorial with Python P6. In this tutorial, I have shown, how to get file name and content of the file from the S3 bucket, when AWS Lambda gets triggered on file drop in S3. Since AWS Lambda is meant to be a series of functions, I’m going to create one function at a time, starting with downloading. In future posts, I’ll work on aspects like processing. IAM Policy for Download Job. By design, I’m creating a policy that only has access to a few operations against one bucket. Download image from S3 bucket to Lambda temp folder (Node.js) I have a simple question: How do I download an image from a S3 bucket to Lambda function temp folder for processing? Basically, I need to attach it to an email (this I can do when testing locally). I have tried: s3.download_file(bucket, key, '/tmp/image.png') I have written a AWS Lambda Function, Its objective is that on invocation - it read the contents of a file say x.db, get a specific value out of it and return to the caller.But this x.db file changes time to time. So I would like to upload this x.db file to S3 and read it from AWS Lambda function as like reading a file. Usually to unzip a zip file that’s in AWS S3 via Lambda, the lambda function should 1. Read it from S3 (by doing a GET from S3 library) 2. Open it via ZIP library (via [code ]ZipInputStream[/code] class in Java, [code ]zipfile[/code] module in Pyt
