Target AWS Services

Terraform Modules from this package were written to manage the following AWS Services with Terraform.

• AWS ELB (Elastic Load Balancing)
  • ALB (Application Load Balancer)
    • Load Balancer
    • Listener
    • Target Group (Instance / IP / Lambda)
  • NLB (Network Load Balancer)
    • Load Balancer
    • Listener
    • Target Group (Instance / IP / ALB)
  • GWLB (Gateway Load Balancer)
    • Load Balancer
    • Listener
    • Target Group (Instance / IP)

Examples

• ALB with Instance Target Group
• ALB with IP Target Group

NLB (Network Load Balancer)

• NLB with Instance Target Group
• NLB with IP Target Group
• NLB with ALB Target Group

GWLB (Gateway Load Balancer)

• GWLB with Instance Target Group
• GWLB with IP Target Group

Support `rules` for `alb-listener`

Support `stickiness` variable of `alb-ip-target-group`

resource/aws_lb_target_group: Add support for target_failover and stickiness attributes for GENEVE protocol target groups

• Release - v4.38.0

Support `health_check` variable of `nlb-alb-target-group`

Support `default_security_group` for `alb`

Support `stickiness` variable of `nlb-ip-target-group`

resource/aws_lb_target_group: Don't force recreation on health_check attribute changes

• https://github.com/hashicorp/terraform-provider-aws/releases/tag/v4.46.0
• hashicorp/terraform-provider-aws#28018

Support `fixed-response` default action type of `alb`

resource/aws_lb_target_group: Allow timeout to be set for TCP health checks

• hashicorp/terraform-provider-aws#28018

Support `auth` for `rules` of `alb-listener`

resource/aws_lb_target_group: Allow healthy_threshold and unhealthy_threshold to be set to different values for TCP health checks.

• https://github.com/hashicorp/terraform-provider-aws/releases/tag/v4.46.0
• hashicorp/terraform-provider-aws#28018

Change `target_group` variable to use `name` instead of `arn` in load balancer listeners

Add example for `alb-with-ip-target-group`

Support `health_check` variable of `alb-lambda-target-group`

Limit only 1 target for `nlb-alb-target-group`

Cannot be determined `for_each` in `rules` variable of `alb-listener` module

 > tf apply
╷
│ Error: Invalid for_each argument
│
│   on ../../modules/alb-listener/main.tf line 148, in resource "aws_lb_listener_rule" "this":
│  148:   for_each = {
│  149:     for rule in var.rules :
│  150:     rule.priority => rule
│  151:   }
│     ├────────────────
│     │ var.rules will be known only after apply
│
│ The "for_each" value depends on resource attributes that cannot be determined until apply, so Terraform cannot predict how many instances will be created. To work around this, use the -target argument to first apply only the resources that the for_each depends on.

Add example for `nlb-with-alb-target-group`

Support `auth` default action type of `alb`

Support `traffic-port` for health check of load balancer listeners
