How do you output a variable in Terraform?
Output values are like the return values of a Terraform module, and have several uses:
- A child module can use outputs to expose a subset of its resource attributes to a parent module.
- A root module can use outputs to print certain values in the CLI output after running terraform apply .
What are Terraform outputs?
Terraform output values allow you to export structured data about your resources. You can use this data to configure other parts of your infrastructure with automation tools, or as a data source for another Terraform workspace. Outputs are also necessary to share data from a child module to your root module.
How are output values declared in a module?
Each output value exported by a module must be declared using an output block: The label immediately after the output keyword is the name, which must be a valid identifier. In a root module, this name is displayed to the user; in a child module, it can be used to access the output’s value.
Is there a way to import a module in Python?
There are various ways to import modules. They are listed below.. We can import a module using the import statement and access the definitions inside it using the dot operator as described above. Here is an example.
Can a child module print a parent module’s output?
A child module can use outputs to expose a subset of its resource attributes to a parent module. A root module can use outputs to print certain values in the CLI output after running terraform apply .
How does the root module print its values?
A root module can use outputs to print certain values in the CLI output after running terraform apply. When using remote state, root module outputs can be accessed by other configurations via a terraform_remote_state data source. Resource instances managed by Terraform each export attributes whose values can be used elsewhere in configuration.
