Multiple variable files

[Ron Pantofaro]

Ok, so I started working with 0.3. Until now I had my variables separated logically between a few files and they also have hierarchy to them.

Now I saw that unless I specify their values in terraform.tfvars (or some other file) it asks me for all the variable values (or keep defaults).

Is there a way to tell terraform to read from multiple var files? perhaps it's solvable with modules?

Let's say I have two sets of variables. Global vars (for example AWS keys) and infrastructure vars (like dns_name of a web server). I want to be able to hold one "global" var file and "use" it (even if it's linking it like i'm doing today) to all my infrastructures (in each one i have the infrastructure specific variables).

Is this possible? (notice that I don't want the root module to pass parameters to child modules, I want the child modules to be able to read from another file completely , or just have terraform be able to read from more than one file).

Hope it was clear.

Ron,

You can specify `-var-file` to the command-line, but there is no way
to otherwise get multiple var files to work.

Mitchell

would i be able to specify more than one var-file?

and to the module question - is the var files global, or will each module also read a var file in its module folder?

[Mitchell Hashimoto]

Ron,

Yes, you can specify multiple.

Module parameters must be passed in from the module using it (up to
the root module). For example:

module "consul" {
servers = "${var.servers}"
}

You have to explicitly forward/string along variables through modules.
Without it, modules will not ask for input.

Best,
Mitchell

Is there a way to force terraform to be "silent" if a var isn't in terraform.tfvars but it does have a default?
