Terraform module to provision AWS Elastic Beanstalk environment

Searching for Maintainer!

The Cloud Posse team no longer utilizes Beanstalk all that much, but this module is still fairly popular. In an effort to give it the attention it deserves, we're searching for a volunteer maintainer to manage this specific repository's issues and pull requests (of which a number are already stacked up). This is a great opportunity for anyone who is looking to solidify and strengthen their Terraform skillset while also giving back to the SweetOps open source community!

You can learn more about being a SweetOps contributor on our docs site here.

If you're interested, reach out to us via the #terraform channel in the SweetOps Slack or directly via email @ hello@cloudposse.com

This project is part of our comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Usage

IMPORTANT: We do not pin modules to versions in our examples because of the difficulty of keeping the versions in the documentation in sync with the latest released versions. We highly recommend that in your code you pin the version to the exact version you are using so that your infrastructure remains stable, and update versions in a systematic way so that they do not catch you by surprise.

Also, because of a bug in the Terraform registry (hashicorp/terraform#21417), the registry shows many of our inputs as required when in fact they are optional. The table below correctly indicates which inputs are required.

Developing

In general, PRs are welcome. We follow the typical "fork-and-pull" Git workflow.

1. Fork the repo on GitHub
2. Clone the project to your own machine
3. Commit changes to your own branch
4. Push your work back up to your fork
5. Submit a Pull Request so that we can review your changes

NOTE: Be sure to merge the latest changes from "upstream" before making a pull request!
