Terraform module to generate well-formed JSON documents that are passed to the aws_ecs_task_definition Terraform resource as container definitions.
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.
This module is meant to be used as output only, meaning it will be used to create outputs which are consumed as a parameter by Terraform resources or other modules.
Caution: This module, unlike nearly all other Cloud Posse Terraform modules, does not use terraform-null-label.
Furthermore, it has an input named environment which has a completely different meaning than the one in terraform-null-label.
Do not call this module with the conventional context = module.this.context. See the documentation below for the usage of environment.

For a complete example with automated tests, see examples/complete with bats and Terratest for the example test.
