Errors from basic terraform config

[danprince]

Having a tough time getting Stack deployed. I'm working with the absolute basic terraform config:

module "stack" {
  source      = "github.com/segmentio/stack"
  environment = "prod"
  key_name    = "id_rsa"
  name        = "my-app"
}

I've downloaded the terraform binary (v0.7.13), added my public key to us-west-2, run terraform get and terraform plan all without problems. My AWS credentials are added as environment variables. Then I tried terraform apply.

After 10 minutes of trying to create the autoscaling cluster, it gives up and reports the following errors:

Error applying plan:

2 error(s) occurred:

* aws_s3_bucket.logs: Error creating S3 bucket: BucketAlreadyExists: The requested bucket name is not available. The bucket namespace is shared by all users of the system. Please select a different name and try again.
        status code: 409, request id: 4BB52027C19E648C
* aws_autoscaling_group.main: "my-app": Waiting up to 10m0s: Need at least 3 healthy instances in ASG, have 0

This is running on a completely clean new AWS account, so there are no resources kicking around from old projects that could be conflicting.

I hadn't realised that S3 bucket names need to be completely unique, so I swapped the app name to my-app-testing.

1 error(s) occurred:

* aws_iam_role.default_ecs_role: diffs didn't match during apply. This is a bug with Terraform and should be reported as a GitHub Issue.

Also include as much context as you can about your config, state, and the steps you performed to trigger this error.
