0.3.0 (unreleased)
FEATURES:
- Modules: Configuration can now be modularized. Modules can live on GitHub, BitBucket, Git/Hg repos, HTTP URLs, and file paths. Terraform automatically downloads/updates modules for you on request.
- New Command:
init
. This command initializes a Terraform configuration from an existing Terraform module (also new in 0.3). - New Command:
destroy
. This command destroys infrastructure created withapply
. - Terraform will ask for user input to fill in required variables and provider configurations if they aren't set.
terraform apply MODULE
can be used as a shorthand to quickly build infrastructure from a module.- The state file format is now JSON rather than binary. This allows for easier machine and human read/write. Old binary state files will be automatically upgraded.
- You can now specify
create_before_destroy
as an option for replacement so that new resources are created before the old ones are destroyed. - The
count
metaparameter can now contain interpolations (such as variables). - The current index for a resource with a
count
set can be interpolated using${count.index}
. - Various paths can be interpolated with the
path.X
variables. For example, the path to the current module can be interpolated using${path.module}
.
IMPROVEMENTS:
- config: Trailing commas are now allowed for the final elements of lists.
- core: Plugins are loaded from
~/.terraform.d/plugins
(Unix) or%USERDATA%/terraform.d/plugins
(Windows). - helper/schema: Can now have default values. [GH-245]

0.2.0 (August 28, 2014)
BACKWARDS INCOMPATIBILITIES:
- We've replaced the configuration language in use from a C library to
a pure-Go reimplementation. In the process, we removed some features
of the language since it was too flexible:
- Semicolons are no longer valid at the end of lines
- Keys cannot be double-quoted strings:
"foo" = "bar"
is no longer valid. - JSON style maps
{ "foo": "bar" }
are no longer valid outside of JSON. Maps must be in the format of{ foo = "bar" }
(like other objects in the config)
- Heroku apps now require (will not validate without)
region
andname
due to an upstream API change. [GH-239]
FEATURES:
- New Provider:
google
: Manage Google Compute instances, disks, firewalls, and more. - New Provider:

: Manage mailgun domains. - New Function:

: Concatenate multiple strings together. Example:concat(var.region, "-", var.channel)
.
