This file holds the declaration of the load balancer we use in front of the GitLab application hosts, in order to distribute network traffic:

resource "aws_elb" "lb" {
    name_prefix = "${var.environment}-"
    subnets = ["${aws_subnet.public-frontend_az-a.id}", "${aws_subnet.public-frontend_az-b.id}"]

        healthy_threshold = 2
        unhealthy_threshold = 2
        timeout = 3
        target = "TCP:80"
        interval = 30
    }
    listener {
        instance_port = 80
        instance_protocol = "http"
        lb_port = 80
        lb_protocol = "http"
    }
