# Copy this file from https://github.com/cloudposse/terraform-null-label/blob/master/exports/context.tf
# and then place it in your Terraform module to automatically get
# Cloud Posse's standard configuration inputs suitable for passing
# to Cloud Posse modules.
#
# Modules should access the whole context as `module.this.context`
# to get the input variables with nulls for defaults,
# for example `context = module.this.context`,
# and access individual variables as `module.this.<var>`,
# with final values filled in.
#
# For example, when using defaults, `module.this.context.delimiter`
# will be null, and `module.this.delimiter` will be `-` (hyphen).
