How can I run the jar without AWS_ACCESS_KEY and AWS_SECRET_KEY ?

[zachgk]

This repo is a demo described in the blog post at https://aws.amazon.com/blogs/opensource/adopting-machine-learning-in-your-microservices-with-djl-deep-java-library-and-spring-boot/ "that demonstrates a RESTful API implementation that can take images from an Amazon Simple Storage Service (Amazon S3) bucket and stores the object detection results back in S3."

So, this demo in particular won't run if it doesn't have the S3 bucket. You can also just use the DJL Spring Boot Starter directly or work using an earlier part of the original blog post, delete the S3 parts of the demo you don't need, or maybe look into a different blog post like https://examples.javacodegeeks.com/djl-spring-boot-example/

Alternatively, you can also sign up for a free AWS account. Then, you get the access key and secret key as credentials for that account. They charge you for resources that you use above the free tier, but I don't think that this demo should charge anything since you get 5GB of free S3 space which is more than enough.
