ECS Cluster won't launch

[Kgirthofer]

Getting errors across the board - am I missing a crucial file?

Thanks!

Hey Kyle.

Do you have any examples of the error messages?

[Kgirthofer]

Starts with the invalidation of the params

kgirthofer@SR191:~/terraform/tst-cluster$ terraform plan
provider.aws.region
  The region where AWS operations will take place. Examples
  are us-east-1, us-west-2, etc.

  Default: us-east-1
  Enter a value: us-east-1

1 error(s) occurred:

* module root: 
    module container_service_cluster: root_block_device_type is not a valid parameter
    module container_service_cluster: root_block_Device_size is not a valid parameter

and if I remove those to go with standard defaults

kgirthofer@SR191:~/terraform/tst-cluster$ terraform plan 
provider.aws.region
  The region where AWS operations will take place. Examples
  are us-east-1, us-west-2, etc.

  Default: us-east-1
  Enter a value: us-east-1

There are warnings related to your configuration. If no errors occurred,
Terraform will continue despite these warnings. It is a good idea to resolve
these warnings in the near future.

Warnings:

  * module.container_service_cluster.aws_iam_instance_profile.container_instance: "roles": [DEPRECATED] Use `role` instead. Only a single role can be passed to an IAM Instance Profile

It seems like you may have an older version of the module sourced and are trying to supply it parameters added in later versions. For example, root_block_device_type and root_block_device_size were added in version 0.3.0.

Also, the roles -> role deprecation warning was fixed in 0.2.0.

[Kgirthofer]

That's what I thought as well - because your readme references v.1 but I changed it to v.4

Do you have your own base-container-instance.yml.tpl?

The template_cloudinit_config resource inside of the module is defined to be multipart. The one inside of the module is minimal and only tries to connect the compute nodes with an ECS cluster. The module parameter cloud_config is an opportunity for you to supply your own directives (with their own set of template variables).

[Kgirthofer]

Oh man - I feel dumb. I never set the variable ecs_cluster_name in the cloudconfig. Thanks for your help!
