The output command is used to display the values of output variables defined in the configuration. Review the Create a Credential Variable flag for JSON-formatted One very annoying part of this, is it still needs connection to the state file where the plan was made from. Diff .

Terraform will perform the following actions: Plan: 1 to add, 0 to change, 0 to destroy. Check out the official docs to find alternative ways to share data between configurations. Just as with We can retrieve the root module outputs from another Terraform configuration using this data source. An outputed attributes can not only be used for the user reference but it can also act as an input to other resources being created via Terraform. We will increment the minor version, e.g. why? individual instances and typically ignoring the top-level objects altogether. Time to wrap up everything and execute the plan to provision our demo infrastructure. // of the underlying structures we will build this values representation from. Since the format of plan files isn't suited for use with external tools (and likely never will be), Terraform can output a machine-readable JSON representation of a plan file's changes. This is where the, Following up on our previous example, lets say that we would like to create a new subnet in the vpc of our, module.

GitLab integrates with Terraform through CI/CD templates that use GitLab-managed Terraform state and display Terraform changes on merge requests. In practice, this is a good use case when we would like to pass values to other Terraform modules or automation tools without exposing them to the intermediate users. This makes it hard for testing as I can download the .
