lb-fargate-service

Terraform module for a load balanced ECS Service using the Fargate launch type.

It will create the following:

• Application Load Balancer in the subnets you specify:
  • alb_subnets_private if alb_internal = true
  • alb_subnets_public if alb_internal = false
• ECS service
  • Belongs of the cluster specified by ecs_cluster_id
  • Creates tasks in the subnets specified in alb_subnets_private
  • According to the task definition & count that you specify
• IAM roles & policies
• Security groups

Note: The provisioning of the ECS task definition and ECR repository was extracted with version 3.*. Use the web-fargate-app module for similar functionality as previous versions
