clj-aws-s3-localstack-demo

A trivial AWS S3 bucket access demo

You'll need Leiningen to run this.

Access a real AWS S3 bucket in the cloud

Prerequisites:

• a real AWS S3 bucket in the cloud, obviously
• AWS credentials for accessing the bucket

For example, given a bucket called my-bucket in AWS region eu-west-1:

$ lein run eu-west-1 https://s3.eu-west-1.amazonaws.com my-bucket
Success! Bucket my-bucket exists and is accessible in region eu-west-1

Create and access a local S3 bucket on LocalStack

Prerequisites:

• Docker
• Eg. AWS CLI for creating your bucket

# Start LocalStack S3 service in Docker, exposing it to host on port 4572
$ CONTAINER_ID=$(docker run -d -e "SERVICES=s3" -p 4572:4572 --rm localstack/localstack)

# Create my-bucket
$ aws --endpoint-url="http://localhost:4572" s3 mb "s3://my-bucket"
make_bucket: my-bucket

# See if it works
$ lein run region-does-not-matter http://localhost:4572 my-bucket
Success! Bucket my-bucket exists and is accessible in region nil

# Stop the Docker container
$ docker stop $CONTAINER_ID
