Terraform Configurations As JSON File


Code in the Terraform language is stored in plain text files with the .tf file extension. There is also a JSON-based variant of the language that is named with the .tf.json file extension.


Terraform also supports an alternative syntax that is JSON-compatible. This syntax is useful when generating portions of a configuration programmatically, since existing JSON libraries can be used to prepare the generated configuration files.


let's create our first.tf.json file in the present working directory with the below content

{
  "output" : {
     "hello1": {
        "value": "Hello Gaurav"
     }
  }
}


Run the terraform plan command and see the output.

┌──(gaurav㉿learning-ocean)-[~/youtube-course/hello-world-json]
└─$ terraform plan                           

Changes to Outputs:
  + hello1 = "Hello Gaurav"

You can apply this plan to save these new output values to the Terraform state, without changing any real infrastructure.

Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to take exactly these actions if you run "terraform apply" now.
