Why do I get the error "Container.name should not be null or empty"?

Question

We are using terraform to import a ECS solution and for some reason, I can not get pass this error.

aws_ecs_task_definition.clustername: ClientException: Container.name should not be null or empty. 09-Feb-2017 23:35:1 status code: 400

I believe this is coming form this json file, service-prod-server.json

#aws_ecs_task_definition
resource "aws_ecs_task_definition" "cluster-name" {
  family = "cluster-name"
  container_definitions = "${file("task-definitions/service-prod-server.json")}"
}

Here is the top portion of the service-prod-server.json config. I have the name there.

[
  {
    "name": "containername",
    "memory": 7000,
    "image": "imagename",
    "disableNetworking": false,
    "readonlyRootFilesystem": false,

I also have this config defined as well.

#aws_ecs_container_definition
data "aws_ecs_container_definition" "cluster-name" {
  task_definition = "${aws_ecs_task_definition.cluster-name.id}"
  container_name = "containername"
}

Let me know what you guys think

Answer 1

For me, I labeled the environment variable key incorrectly:

{ "key": "myvariable", "value": "myvalue" }

instead of

{ "name": "myvariable", "value": "myvalue" }

The difference is that I wrote key instead of name and that broke the whole container definition, which gave me this error.
