terraform module source variable

Perhaps a similar thing could happen in Terraform. Typically, when you create a plan like: resource "kind" "name" {key = "value"}in Terraform, you can access attributes to be printed at the end of the application using the output block:. Terraform module to create AWS Lambda resources with configurable event sources, IAM configuration (following the principal of least privilege), VPC as well as SSM and log streaming support.. Hence, the source field is given a path to the module folder as shown below: module "local-module" { source = "../local-module" } share | improve this question | follow ... Is it possible to to “variableize” the source path for a module in Terraform? thanks for the help! Previously, when writing your Terraform module, you would need to create a variable for each setting you want to pass to your resource. Deploying WVD02. variable "variable_name" {} terraform apply -var variable_name="value" A Terraform module is very simple: any set of Terraform configuration files in a folder is a module. WVD-as-a-Module [This Post] In this third post in my Learning Terraform series I'll explore the concept of Modules. Variables can be predetermined in a file or included in the command-line options. On the Terraform registry page for the AWS VPC module, you will see an Inputs tab that describes all of the input variables that module supports. When Terraform retrieves module source code from a Git repository, it runs the git command directly with the intent that it will then be able to pick up the credentials you have in your surrounding environment, which would normally allow you to run git directly without explicitly providing credentials. Module { source = "..." region = "${var.region}" } Allow the module to access variables globally with an alternative syntax. Terraform can deduct the type of the variable from the default or input value. AWS Lambda Terraform module. Terraform should generally not be handling your Git credentials directly. Aside from source and version, most of the arguments to a module block will set variable values. Perhaps ${global.region} instead of ${var.region}. In the post Terraform Plans, Modules, and Remote State, I use local modules in the root configuration. The caller of this module can then use vm_depends_on in the same way as the first-class depends_on meta-argument: module "example" { source = "..." vm_depends_on = [module.fw_core01.firewall] } 6. In that case you must define values as outputs from module A then pass them in to module B. Variables are not shared globally across modules so values must be defined as outputs or variables for each module. When using the object type, we can actually combine these settings in a complex structure. Every module declared in a Terraform configuration must come from a source. Sure, you would have maps and lists, but a map could only contain values of the same type, limiting the use of it greatly. Remote State03. i want my source code to get deployed across these regions and want to pass the environment variables to the module. What is a Module? "With Terraform, you can put your code inside of a Terraform module and reuse that module in multiple places throughout your code. However, due to the interpretation of module configuration blocks, the names source, version and providers are reserved for Terraform's own use and are thus not recommended for any module intended to be used as a child module. ... You can access module output variables the same way as resource output attributes. As such, the simplest variable is just a name while the type and value are selected based on the input. The variable block configures a single input variable for a Terraform module. how this can be done? Learning Terraform Series01. Since this variable is being used only for its dependencies and not for its value, I defined it as having type any to get the most flexibility.
