From ccd039c97c5b74669db73a834f89ea6ffa479b61 Mon Sep 17 00:00:00 2001 From: Thomas Hager Date: Wed, 15 Oct 2025 10:00:07 +0200 Subject: [PATCH] Update load_balancing_cross_zone_enabled variable to accept string instead of bool As described in #414, in addition to true and false, the resource aws_lb_target_group accepts the value "use_load_balancer_configuration" for the parameter load_balancing_cross_zone_enabled. This commit updates variables.tf to accept string instead of bool for load_balancing_cross_zone_enabled. --- README.md | 2 +- examples/complete-alb/main.tf | 2 +- variables.tf | 2 +- 3 files changed, 3 insertions(+), 3 deletions(-) diff --git a/README.md b/README.md index 0ee9c52..9371c4d 100644 --- a/README.md +++ b/README.md @@ -436,7 +436,7 @@ No modules. | [subnet\_mapping](#input\_subnet\_mapping) | A list of subnet mapping blocks describing subnets to attach to load balancer |
