是否可以通过 environment_name 变量打开和关闭 access_logs 块? [英] Is it possible to turn the access_logs block on and off via the environment_name variable?

问题描述

我正在考虑在 新条件>Terraform v0.11 基本上根据环境打开或关闭配置块.

I'm looking at using the new conditionals in Terraform v0.11 to basically turn a config block on or off depending on the evnironment.

这里是我想变成条件的块，例如，如果我有一个变量要为生产打开.

Here's the block that I'd like to make into a conditional, if, for example I have a variable to turn on for production.

access_logs {
    bucket = "my-bucket"
    prefix = "${var.environment_name}-alb"
}

我认为我有条件检查环境的逻辑，但我不知道如何将上述配置粘贴到逻辑中.

I think I have the logic for checking the environment conditional, but I don't know how to stick the above configuration into the logic.

"${var.environment_name == "production" ? 1 : 0 }"

是否可以通过 environment_name 变量打开和关闭 access_logs 块?如果这不可能，是否有解决方法?

Is it possible to turn the access_logs block on and off via the environment_name variable? If this is not possible, is there a workaround?

推荐答案

在当前的terraform中，if语句只是一个值，不能用于block.

In the current terraform, the if statement is only a value and can not be used for the block.

在这种情况下有一个解决方法.您可以将 access_log 块的 enabled 属性设置为 false.请注意，这不是通用解决方案，只能与 access_log 块一起使用.

There is a workaround in this case. You can set the enabled attribute of the access_log block to false. Note that this is not a general solution but can only be used with the access_log block.

access_logs {
    bucket  = "my-bucket"
    prefix  = "${var.environment_name}-alb"
    enabled = "${var.environment_name == "production" ? true : false }"
}
