Clarification on TaskDefinition Launch Type

[carpiediem]

I'm getting an error on one of the last lines of your .circleci/config.yml file and I think it's because I set up my AWS infrastructure incorrectly. Here's the error that CircleCI is reporting for the aws ecs update-service command:
An error occurred (InvalidParameterException) when calling the UpdateService operation: Task definition does not support launch_type FARGATE.

I'm new to ECS and couldn't figure out the setup based on your bullet points alone. I followed CircleCI's suggestion of using terraform to create an AWS stack.

It looks like CircleCI's terrafrom configuration uses AWS Fargate, but your task definition is meant for EC2-type clusters. Is that correct?

Is there any guidance you can add (or a tutorial you can recommend) on how a cluster should be configured for use here? Thanks, in advance, for any pointers.

FYI, I was hoping that I might get this working by just tweaking register-task-definition command, but a new error is complaining about the option I've added. I'm not sure why, since it seems to work this way in AWS' docs.

The change:

# Register task definition
json=$(aws ecs register-task-definition --container-definitions "$task_def" --family "$FAMILY" --requires-compatibilities FARGATE)

The error:

usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:

  aws help
  aws <command> help
  aws <command> <subcommand> help

Unknown options: --requires-compatibilities, FARGATE
