然后,使用现有图像的配置可以假设它存在,而无需关心它是否由其他 Terraform 配置创建。 在Terraform 文档部分Module Composition 中对这种情况有更详细的概述,特别是子部分Conditional Creation of Objects。该指南侧重于单个配置中模块之间的交互,但相同的基本原则也适用于配置之间的依赖关系(通过数据源)。
而Terraform conditional if是一种条件语句,用于根据特定条件执行不同的操作。 在使用Terraform时,可以结合for_each和条件语句if来实现更灵活的资源管理和配置。 使用for_each时,可以传入一个集合或映射作为参数。Terraform会根据集合或映射中的每个元素创建对应的资源实例。例如,可以使用for_each来创建多个虚拟机实例,每个...
You can now make use of this module in the stage environment.The syntax for using a module is: module"NAME"{source="SOURCE"[CONFIG...]} Within the module definition, thesourceparameter specifies the folder where the module’s code can be found.For example, you can create a new file in...
HashiCorp Terraform has an inline If/Else conditional expression that enables you to set parameters and variables programmatically based on the condition
The main configuration utilizes this module to perform the merge and outputs the final result. The expansion symbol (...) in Terraform is a versatile tool for dynamically managing and merging lists of maps or objects. By understanding and leveraging this feature, you can create more flexible, ...
Conditional creation有时您需要有条件地创建EKS资源,但是Terraform不允许在module块内使用count,所以解决方案是指定参数create_eks。使用此特性并拥有manage_aws_auth=true(默认值)需要以允许数据源不存在的方式设置kubernetes提供程序。data "aws_eks_cluster" "cluster" { count = var.create_eks ? 1 : 0 name =...
Thecountmeta-argument lets you create multiple instances of a resource from a single resource block. Refer to thecount meta-argument documentationfor examples. A common practice to conditionally create resources is to use thecountmeta-argument with aconditional expression. In the following example, T...
The next step in the workflow is initialising Terraform within the runner. The Terraform init command prepares the working directory for use with Terraform. It initializes the backend, child module installation and plugin installation. You can see in the code here we’re configuring the backend an...
