terraform-provider-compose2ecs

A terraform plugin containing a datasource that can transform a docker compose file into an ecs task definition.

usage

data "compose2ecs" "compose" {}

resource "aws_ecs_task_definition" "app" {
  family                = "${var.app}"
  container_definitions = "${data.compose2ecs.compose.container_definitions}"
}

You can optionally specify compose_file if you want to override the default compose file name (defaults to docker-compose.yml). You can also optionally specify which subset of services from the compose file you want to include (defaults to all).

data "compose2ecs" "compose" {
  compose_file = "my-compose.yml"
  services     = ["web", "worker"]
}

where docker-compose.yml might look like...

version: "2"
services:  
  web:
    container_name: web
    image: 618440173123.dkr.ecr.us-east-1.amazonaws.com/web:$VERSION
    ports:
      - 80:80
    labels: 
      compose2ecs.hostPort: "0"
      compose2ecs.memoryReservation: "1000"

and the outputted container_definitions would be...

[
  {
    "Name": "web",    
    "Image": "618440173123.dkr.ecr.us-east-1.amazonaws.com/web:1.0",
    "MemoryReservation": 1000,
    "PortMappings": [
      {
        "ContainerPort": 80,
        "HostPort": 0
      }
    ]
  }
]
