#----------------------------
#1. Create custom vpc
#----------------------------

resource "aws_vpc" "production_environment" {
  cidr_block = "10.0.0.0/16"
}

#----------------------------
#2. Create Internet gateway
#----------------------------

  vpc_id = aws_vpc.production_environment.id

}

#----------------------------
#3. Create custom route table
#----------------------------

#4. Create subnet
#-------------------

#------------------------------------
#5. Associate subnet with route table
#------------------------------------
