some aws java utils

Primary LanguageJava

AWS S3 util test class

Simple java project, to test uploading a file to S3 with...

  • Setting an ACL (Assuming a cross account Bucket Policy Setup)
  • Assuming a role (Assumes a cross account role setup)

... after, in my case, configuring a cross account bucket policy and/or a cross account role.

Pre-requisites

  • java 1.8
  • maven
  • an existing s3 bucket
  • an existing cross account bucket (or role)

Running

Execute the following:

AWS_PROFILE=sandbox \
    make run \
        BUCKET_NAME="my-bucket-name" \
        ROLE_TO_ASSUME_NAME="my-role-to-assume"

This will:

  • Build the project with mvn
  • Run the java app, to put the file in the target bucket
  • If ROLE_TO_ASSUME is NOT provided, the app will simply push directly to the bucket (assumes a cross account bucket policy has been setup), and use an ACL during the PUT.
  • If ROLE_TO_ASSUME IS provided, credentials for that role will be retrived and used for the subsequent push.
