Terraform module to provision AWS Elastic Beanstalk environment
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!
Security scanning is graciously provided by Bridgecrew. Bridgecrew is the leading fully hosted, cloud-native solution providing continuous Terraform security and compliance.
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.
