Terraform uses text files to describe infrastructure and to set variables.
|
|
|
|
|
These text files are called Terraform _configurations_ and end in `.tf`. This

|

section talks about the format of these files as well as how they're loaded.

Terraform uses text files to describe infrastructure and to set variables.
|
|
|
|
|
These text files are called Terraform _configurations_ and end in
|
|
|
|
|
`.tf`. This section talks about the format of these files as well as
|
|
|
|
|
how they're loaded.
|
|
|
|
|
|
|
|
|
|
The format of the configuration files are able to be in two formats:
|
|
|
|
|
Terraform format and JSON. The Terraform format is more human-readable,
|
|
|
|
|
supports comments, and is the generally recommended format for most
|
|
|
|
|
Terraform files. The JSON format is meant for machines to create,
|
|
|
|
|
modify, and update, but can also be done by Terraform operators if
|
|
|
|
|
you prefer. Terraform format ends in `.tf` and JSON format ends in
|
|
|
|
|
`.tf.json`.
