Configuring the Elastic Load balancer

Firstly, we need to create a security group resource for our ELB by adding this code to main.tf:

    # A security group for the ELB so it is accessible via the web 
     resource "aws_security_group" "elb" { 
     name        = "cna_sg_elb" 
     description = "Security_group_elb" 
     vpc_id      = "${aws_vpc.default.id}" 
  
    # HTTP access from anywhere 
    ingress { 
      from_port   = 5000 
      to_port     = 5000 
      protocol    = "tcp" 
      cidr_blocks = ["0.0.0.0/0"] 
     } 
  
    # outbound internet access 
    egress { 
      from_port   = 0 
      to_port     = 0 
      protocol    = "-1" 
      cidr_blocks = ["0.0.0.0/0"] 
     } 

Now, we need to add the following configuration for creating the ELB resources, and to add the app server into it as well:

 resource "aws_elb" "web" { name = "cna-elb" subnets = ["${aws_subnet.default.id}"] ...
