Yes. Terraform will check for (and read) TF_DATADIR/system.terraformrc and then $HOME/.terraformrc where TF_DATADIR is a variable set at compile time. To find out the resource file settings terrafrom was compiled with, you can say
| terraform --helprc |
and it will tell you what it's resource file locations are. To install a terraform resource file, you can use the builtin method of
| terraform --installrc |
to have terraform write the configuration file .terraformrc with the default settings to your home directory. Finally you can say
| terraform --helprc |
to see the resource file settings terrafrom was compiled with and get a list of supported resource file options.
The format of the resource file is very simple. The first 2-letter prefix of the option name refers to the option's type and thus specifies what kind of paramter it expects:
Terraform resource file parameter types
| Resource Prefix | Data Type | Sample Data |
|---|---|---|
| b_ | boolean | 0(FALSE), 1(TRUE) |
| i_ | integer | 1, 2, 3, 4, ... |
| f_ | float | 0.1234, 987.321, Pi, ... |
| s_ | string | any string, typically a file name/path |
