Terraform syntax

Terraform files use the extension *.tf.
It is based on the HCF language.
Files must be UTF-8 encoded, and the convention is to use unix line endings.

Overview

• blocks contain configuration for an object using a key/value format
• labels can optionally be assigned a block (as many as you'd like)
• arguments are how the key-value assignments within a block are referred to.

# ${BLOCK_TYPE} [${LABEL}..] {
#   ${IDENTIFIER} = ${EXPRESSION}  # argument
# }

resource "aws_vpc" "main" {
  cidr_block = var.base_cidr_block
}
