Besides, what is the output variable?

A variable is an input variable if its Input property is Yes. Its value can be input from an external source, such as an Architect call flow. A variable whose Output property is Yes is an output variable. When the script runs, any value assigned to the variable is saved for use outside of the script.

Subsequently, question is, what is terraform plan command? The terraform plan command is used to create an execution plan. Terraform performs a refresh, unless explicitly disabled, and then determines what actions are necessary to achieve the desired state specified in the configuration files.

Also, how do you use output variables in terraform?

Start by creating an output variables file called output.tf and open it for edit. Add the following three variable definitions in the file to output the server's IP addresses and hostname after deployment. Replace the server_name with the name of your Terraform host.

What is terraform refresh?

The terraform refresh command is used to reconcile the state Terraform knows about (via its state file) with the real-world infrastructure. This can be used to detect any drift from the last-known state, and to update the state file. This does not modify infrastructure, but does modify the state file.

How do you find the input and output?

The rule for the input-output table below is: add 1.5 to each input number to find its corresponding output number. Use this rule to find the corresponding output numbers. To find each output number, add 1.5 to each input number. Then, write that output number in the table.

Is domain input or output?

The domain is the input, the independent value—it's what goes into a function. The range is the output, the dependent value—it's what comes out. Domain and range may be limited to a few discrete values, or they may include all numbers everywhere, to infinity and beyond.

How do I use modules in terraform?

The . tf files in your working directory when you run terraform plan or terraform apply together form the root module. That module may call other modules and connect them together by passing output values from one to input values of another. To learn how to use modules, see the Modules configuration section.

How do I rollback terraform?

The usual way to represent "rolling back" in Terraform is to put your configuration in version control and commit before each change, and then you can use your version control system's features to revert to an older configuration if needed. Not all changes can be rolled back purely by reverting a VCS change though.
