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.
