Command: output

The terraform output command is used to extract the value of an output variable from the state file.

Usage

Usage: terraform output [options] NAME

By default, output requires only a variable name and looks in the current directory for the state file to query.

The command-line flags are all optional. The list of available flags are:

• -json - If specified, the outputs are formatted as a JSON object, with a key per output. This can be piped into tools such as jq for further processing.
• -state=path - Path to the state file. Defaults to "terraform.tfstate".
• -module=module_name - The module path which has needed output. By default this is the root path. Other modules can be specified by a period-separated list. Example: "foo" would reference the module "foo" but "foo.bar" would reference the "bar" module in the "foo" module.
