subnets

Define subnets using the following schema:

subnets:

  human-readable-custom-name:

      size: cidr_integer
      route_table: name-of-the-route-table
      description: human readable description (optional)
      availability_zone: char of az (optional)

Example code snippet from subnets.yaml:

# This is an example of a 4 subnet schema.
# Each subnet has a size of 27 which is a /27 CIDR (32 addresses).
# Two are attached to the private route_table, and two to the public.
# We round robin AZ letters if availability_zone is not defined.
# Instances will launch into subnet with public IPs, if public is True.
