Necessary policies when creating a Beanstalk App through Terraform. This is autogenerated by cli, but needs to be specified if using Terraform.

to get this to work I had to change the assume permissions when creating the role

resource "aws_iam_role" "beanstalk_service" {
    name = "beanstalk-service"
    assume_role_policy = <<EOF
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "elasticbeanstalk.amazonaws.com"
      },
      "Action": "sts:AssumeRole",
      "Condition": {
        "StringEquals": {
          "sts:ExternalId": "elasticbeanstalk"
        }
      }
    }
  ]
}
EOF
}

resource "aws_iam_role" "beanstalk_ec2" {
  name = "beanstalk-ec2"
  assume_role_policy = <<EOF
{
  "Version": "2008-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "ec2.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
EOF
}

I also ended up adding

resource "null_resource" "setup_roles"{
  depends_on = [
    "aws_iam_role.beanstalk_service",
    "aws_iam_instance_profile.beanstalk_service",
    "aws_iam_policy_attachment.beanstalk_service",
    "aws_iam_policy_attachment.beanstalk_service_health",
    "aws_iam_role.beanstalk_ec2",
    "aws_iam_instance_profile.beanstalk_ec2",
    "aws_iam_policy_attachment.beanstalk_ec2_container",
    "aws_iam_policy_attachment.beanstalk_ec2_web",
    "aws_iam_policy_attachment.beanstalk_ec2_worker"
  ]
}

because if you are working with targets the dependency graph does not fully populate from the beanstalk env.
