Terraform 0.14 Introduces a Dependency Lock File for Providers

New dependency lock files in Terraform 0.14 help duplicate previous runs so they use exactly the same provider versions.

Terraform 0.14 introduces a new dependency lock file, focused on providers, to simplify managing Terraform automation. Starting in Terraform 0.13, the possibility to install providers from customer-controlled or third-party remote registries increases the need to be able to replicate Terraform runs in automation. These remote and automated Terraform workflows need to be able to duplicate previous runs exactly.

The dependency lock file launching with Terraform 0.14 is generated automatically when Terraform init is run. The generated lockfile should be committed into version control systems so that Terraform can guarantee to select exactly the same provider versions on future runs.

Upgrading to a new provider (or collection of providers) can be completed via terraform init -upgrade.

Example of a lockfile entry:

  1. provider "registry.terraform.io/hashicorp/azurerm" {
  2. version = "2.30.0"
  3. constraints = "~> 2.12"
  4. hashes = [
  5. "h1:FJwsuowaG5CIdZ0WQyFZH9r6kIJeRKts9+GcRsTz1+Y=",

  18. ]
  19. }

If you don’t want to use this new behavior you can run terraform init -upgrade and discard .terraform.lock immediately after it is created. The lockfile can equally be added to a list of files ignored by version control.
