Terraform module which creates ECS (Elastic Container Service) resources on AWS.
- ECS cluster w/ Fargate or EC2 Auto Scaling capacity providers
- ECS Service w/ task definition, task set, and container definition support
- Separate sub-modules or integrated module for ECS cluster and service
For more details see the design doc
This project supports creating resources through individual sub-modules, or through a single module that creates both the cluster and service resources. See the respective sub-module directory for more details and example usage.
