aws_elb

Provides an Elastic Load Balancer resource.

~> NOTE on ELB Instances and ELB Attachments: Terraform currently provides both a standalone ELB Attachment resource (describing an instance attached to an ELB), and an ELB resource with instances defined in-line. At this time you cannot use an ELB with in-line instaces in conjunction with a ELB Attachment resources. Doing so will cause a conflict and will overwrite attachments.

Example Usage

# Create a new load balancer
resource "aws_elb" "bar" {
  name = "foobar-terraform-elb"
  availability_zones = ["us-west-2a", "us-west-2b", "us-west-2c"]

  access_logs {
    bucket = "foo"
    bucket_prefix = "bar"
    interval = 60
  }

  listener {
    instance_port = 8000
    instance_protocol = "http"
    lb_port = 80
    lb_protocol = "http"
  }

  listener {
    instance_port = 8000
    instance_protocol = "http"
    lb_port = 443
    lb_protocol = "https"
    ssl_certificate_id = "arn:aws:iam::123456789012:server-certificate/certName"
  }

  health_check {
    healthy_threshold = 2
    unhealthy_threshold = 2
    timeout = 3
    target = "HTTP:8000/"
    interval = 30
  }

  instances = ["${aws_instance.foo.id}"]
  cross_zone_load_balancing = true
  idle_timeout = 400
  connection_draining = true
  connection_draining_timeout = 400

  tags {
    Name = "foobar-terraform-elb"
  }
}

Argument Reference

The following arguments are supported:

Exactly one of availability_zones or subnets must be specified: this determines if the ELB exists in a VPC or in EC2-classic.

Access Logs (access_logs) support the following:

Listeners (listener) support the following:

Health Check (health_check) supports the following:

Note on ECDSA Key Algorithm

If the ARN of the ssl_certificate_id that is pointed to references a certificate that was signed by an ECDSA key, note that ELB only supports the P256 and P384 curves. Using a certificate signed by a key using a different curve could produce the error ERR_SSL_VERSION_OR_CIPHER_MISMATCH in your browser.

Attributes Reference

The following attributes are exported:

Import

ELBs can be imported using the name, e.g.

$ terraform import aws_elb.bar elb-production-12345
