0.4.0 (April 2, 2015)

BACKWARDS INCOMPATIBILITIES:

  • Commands terraform push and terraform pull are now nested under the remote command: terraform remote push and terraform remote pull. The old remote functionality is now at terraform remote config. This consolidates all remote state management under one command.
  • Period-prefixed configuration files are now ignored. This might break existing Terraform configurations if you had period-prefixed files.
  • The block_device attribute of aws_instance has been removed in favor of three more specific attributes to specify block device mappings: root_block_device, ebs_block_device, and ephemeral_block_device. Configurations using the old attribute will generate a validation error indicating that they must be updated to use the new fields [GH-1045].

  • Self-variables can be used to reference the current resource's attributes within a provisioner. Ex. ${self.private_ip_address} [GH-1033]
  • Continuous state saving during terraform apply. The state file is continuously updated as apply is running, meaning that the state is less likely to become corrupt in a catastrophic case: terraform panic or system killing Terraform.
  • Math operations in interpolations. You can now do things like ${count.index+1}. [GH-1068]
  • New AWS SDK: Move to aws-sdk-go (hashicorp/aws-sdk-go), a fork of the official awslabs repo. We forked for stability while awslabs refactored the library, and will move back to the officially supported version in the next release.

IMPROVEMENTS:

  • New config function: format - Format a string using sprintf format. [GH-1096]
  • New config function: replace - Search and replace string values. Search can be a regular expression. See documentation for more info. [GH-1029]

  • providers/aws: Full support for block device mappings on instances and launch configurations [GH-1045, GH-1364]
  • provisioners/remote-exec: SSH agent support. [GH-1208]

BUG FIXES:

  • core: module outputs can be used as inputs to other modules [GH-822]
  • core: Self-referencing splat variables are no longer allowed in provisioners. [GH-795][GH-868]
  • core: Validate that depends_on doesn't contain interpolations. [GH-1015]
