Can Terraform modules use other modules?
Child Modules A Terraform module (usually the root module of a configuration) can call other modules to include their resources into the configuration. Child modules can be called multiple times within the same configuration, and multiple configurations can use the same child module.
How do I use multiple modules in terraform?
Execute Terraform commands on multiple modules at once
- The run-all command. Passing outputs between modules. Unapplied dependency and mock outputs. Dependencies between modules. Testing multiple modules locally. Limiting the module execution parallelism.
- graph-dependencies.
How do you specify depends on terraform?
Use the depends_on meta-argument to handle hidden resource or module dependencies that Terraform can’t automatically infer. Explicitly specifying a dependency is only necessary when a resource or module relies on some other resource’s behavior but doesn’t access any of that resource’s data in its arguments.
Can a module draw a dependency on another module?
Just wanted to mention that while we don’t yet support whole-module dependencies, there’s nothing stopping you from wiring an output of one module into an input of another, which will effectively draw a dependency between the appropriate resources.
Can you create indirect dependencies on a module?
For the rare situation where automatic dependency detection is insufficient, you can still exploit the fact that module variables and outputs are nodes in the dependency graph to create indirect explicit dependencies, like this:
Why does terraform automatically infer dependency between modules?
If the configuration for one resource refers directly or indirectly to another, Terraform automatically infers the dependency between them without the need for explicit depends_on. This works because module variables and outputs are also nodes in the dependency graph: if a child module resource refers to var.foo then it indirectly depends on
Why do we need a dependson module in PowerShell?
Powershell: DependsOn Module One nice feature of a DSC configuration is that all resources support specifying a DependsOn property that ensures that the resources that it depends on are ran first. Every once in a while, I find myself wanting to use that feature in other scripts. I created a module called DependsOn to do that for me.
