Terraform module for creating and managing AWS Elastic Container Service (ECS) clusters and services with Fargate or EC2 capacity providers.
terraform-aws-ecs is a Terraform module that automates the provisioning of AWS Elastic Container Service infrastructure. It creates and manages ECS clusters, services, task definitions, and associated AWS resources like IAM roles, security groups, and capacity providers. The module solves the problem of manually configuring complex ECS deployments by providing a standardized, repeatable infrastructure-as-code solution.
DevOps engineers, infrastructure teams, and cloud architects who manage containerized applications on AWS ECS using Terraform for infrastructure provisioning.
Developers choose this module because it provides production-ready ECS configurations with sensible defaults, reduces boilerplate Terraform code, and follows AWS best practices. It's maintained by the Terraform AWS Modules community with regular updates for new AWS features.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Deploys ECS clusters with integrated service definitions in a single module, reducing boilerplate code and ensuring consistency, as shown in the usage example with multiple services.
Supports Fargate, Fargate Spot, EC2 Auto Scaling, and managed instances capacity providers, offering flexibility in scaling and cost optimization, detailed in the cluster_capacity_providers input.
Automatically creates infrastructure, task execution, and task IAM roles with customizable policies, including permissions for secrets and SSM parameters, reducing manual configuration errors.
Built-in configuration for AWS ECS Service Connect namespace and service discovery, simplifying microservices communication, as demonstrated in the service_connect_configuration example.
Provides sensible defaults like enabled container insights and configurable security groups, while allowing full overrides for enterprise-grade deployments.
With over 100 input variables and deeply nested objects, the module has a steep learning curve, making it difficult to debug or customize without extensive Terraform and AWS ECS expertise.
Deprecation warnings such as 'disable_v7_default_name_description' indicate future breaking changes in v8.0, requiring teams to actively manage version updates and migrations.
Deeply integrated with AWS-specific APIs and services, making it challenging to migrate to other cloud providers or container orchestration platforms like Kubernetes.
The lengthy README and design doc, while comprehensive, can overwhelm new users, necessitating additional trial-and-error or community support for effective use.
