Debug Output

Panic Output

Expected Behavior

When we add description to ingress/egress blocks we are able to use lookup on their properties.

Actual Behavior

When description is added lookup doesn't find any properties of either ingress or egress objects and produces this error:

Error: Error running plan: 1 error(s) occurred:

* module.rabbitmq.data.template_file.port: 3 error(s) occurred:

* module.rabbitmq.data.template_file.port[2]: lookup: lookup failed to find 'description' in:

${format("%s/%s", lookup(aws_security_group.rabbitmq.ingress[count.index], "description"), lookup(aws_security_group.rabbitmq.ingress[count.index], "protocol"))}
* module.rabbitmq.data.template_file.port[0]: lookup: lookup failed to find 'description' in:

${format("%s/%s", lookup(aws_security_group.rabbitmq.ingress[count.index], "description"), lookup(aws_security_group.rabbitmq.ingress[count.index], "protocol"))}
* module.rabbitmq.data.template_file.port[1]: lookup: lookup failed to find 'description' in:

${format("%s/%s", lookup(aws_security_group.rabbitmq.ingress[count.index], "description"), lookup(aws_security_group.rabbitmq.ingress[count.index], "protocol"))}

Steps to Reproduce

1. Create aws_security_group resource (for example):

resource "aws_security_group" "rabbitmq" {
  name = "rabbitmq"
  description = "RabbitMQ server access rules"
  ingress {
    description = "SSH"
    from_port = 22
    to_port = 22
    protocol = "tcp"
    cidr_blocks = [
      "0.0.0.0/0"
    ]
  }
  ingress {
    description = "RabbitMQ"
    from_port = 5672
    to_port = 5672
    protocol = "tcp"
    cidr_blocks = [
      "0.0.0.0/0"
    ]
  }
  ingress {
    description = "RabbitMQ web administration"
    from_port = 15672
    to_port = 15672
    protocol = "tcp"
    cidr_blocks = [
      "0.0.0.0/0"
    ]
  }
  egress {
    description = "Allow all outbound connections"
    from_port = 0
    to_port = 0
    protocol = "-1"
    cidr_blocks = [
      "0.0.0.0/0"
    ]
  }
  tags {
    Name = "rabbitmq"
  }
}

2. Create data source for formatted template:

data "template_file" "port" {
  count = "${length(aws_security_group.rabbitmq.ingress)}"
  template = "${format("%s/%s", lookup(aws_security_group.rabbitmq.ingress[count.index], "from_port"), lookup(aws_security_group.rabbitmq.ingress[count.index], "protocol"))}"
}

3. terraform apply
