- Update version constraints of Terraform core, providers, and modules
- Update dependency lock files (.terraform.lock.hcl) without Terraform CLI
- Update all your Terraform configurations and lock files recursively under a given directory
- Get the latest release version from the GitHub, GitLab, or Terraform Registry
- Terraform v0.12+ support
If you integrate tfupdate with your favorite CI or job scheduler, you can check the latest release daily and create a Pull Request automatically.
It is a best practice to break your Terraform configuration and state into small pieces to minimize the impact of an accident. It is also recommended to lock versions of Terraform core, providers and modules to avoid unexpected breaking changes. If you decided to lock version constraints, you probably want to keep them up-to-date frequently to reduce the risk of version upgrade failures. It's easy to update a single directory, but what if they are scattered across multiple directories?
That is why I wrote a tool which parses Terraform configurations and updates all version constraints at once.
If you are a macOS user, you can install tfupdate via either Homebrew or MacPorts:
$ brew install minamijoyo/tfupdate/tfupdate$ sudo port install tfupdateDownload the latest compiled binaries and put it anywhere in your executable path.
https://github.com/minamijoyo/tfupdate/releases
If you have Go 1.22+ development environment:
$ go install github.com/minamijoyo/tfupdate@latest
$ tfupdate --version
You can also run it with Docker:
$ docker run -it --rm minamijoyo/tfupdate --version
$ tfupdate --help
Usage: tfupdate [--version] [--help] <command> [<args>]
Available commands are:
lock Update dependency lock files
module Update version constraints for module
provider Update version constraints for provider
release Get release version information
terraform Update version constraints for terraform
$ tfupdate terraform --help
Usage: tfupdate terraform [options] <PATH>
Arguments
PATH A path of file or directory to update
Options:
-v --version A new version constraint (default: latest)
If the version is omitted, the latest version is automatically checked and set.
-r --recursive Check a directory recursively (default: false)
-i --ignore-path A regular expression for path to ignore
If you want to ignore multiple directories, set the flag multiple times.
If you have main.tf like the following:
$ cat main.tf
terraform {
required_version = "0.12.15"
}
Execute the following command:
$ tfupdate terraform -v 0.12.16 main.tf
$ cat main.tf
terraform {
required_version = "0.12.16"
}
A value of version flag accepts any string literal. You can also pass a version constraint:
$ tfupdate terraform -v "~> 1.0" main.tf
$ cat main.tf
terraform {
required_version = "~> 1.0"
}
If you want to update all your Terraform configurations under the current directory recursively,
use -r (--recursive) option:
$ tfupdate terraform -v 0.12.16 -r ./
You can also ignore some path patterns with -i (--ignore-path) option:
$ tfupdate terraform -v 0.12.16 -i modules/ -r ./
If the version is omitted, the latest version is automatically checked and set.
$ tfupdate terraform -r ./
$ tfupdate provider --help
Usage: tfupdate provider [options] <PROVIDER_NAME> <PATH>
Arguments
PROVIDER_NAME A name of provider (e.g. aws or integrations/github)
PATH A path of file or directory to update
Options:
-v --version A new version constraint (default: latest)
If the version is omitted, the latest version is automatically checked and set.
-r --recursive Check a directory recursively (default: false)
-i --ignore-path A regular expression for path to ignore
If you want to ignore multiple directories, set the flag multiple times.
$ cat main.tf
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "3.70.0"
}
}
}
$ tfupdate provider aws -v 3.74.0 main.tf
$ cat main.tf
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "3.74.0"
}
}
}
A value of version flag accepts any string literal. You can also pass a version constraint:
$ tfupdate provider aws -v "~> 3.0" main.tf
$ cat main.tf
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "~> 3.0"
}
}
}
For updating the dependency lock file (.terraform.lock.hcl), use the tfupdate lock command.
$ tfupdate module --help

If you want to ignore multiple directories, set the flag multiple times.
--source-match-type Define how to match MODULE_NAME to the module source URLs. Valid values are "full" or "regex". (default: full)
$ cat main.tf
module "s3_bucket" {
source = "terraform-aws-modules/s3-bucket/aws"

The tfupdate lock command updates the dependency lock file (.terraform.lock.hcl). For more information on the dependency lock file, see the official Terraform documentation: https://developer.hashicorp.com/terraform/language/files/dependency-lock
$ tfupdate lock --help
Usage: tfupdate lock [options] <PATH>
Arguments
PATH A relative path of directory to update
Options:
--platform Specify a platform to update dependency lock files.
At least one or more --platform flags must be specified.
Use this option multiple times to include checksums for multiple target systems.
Target platform names consist of an operating system and a CPU architecture.
(e.g. linux_amd64, darwin_amd64, darwin_arm64)
-r --recursive Check a directory recursively (default: false)
-i --ignore-path A regular expression for path to ignore
If you want to ignore multiple directories, set the flag multiple times.
Given the following configuration:
$ cat test-fixtures/lock/simple/main.tf
terraform {
required_providers {
null = {
source = "hashicorp/null"
version = "3.1.1"
}
}
}
As you know, you can generate the dependency lock file by the terraform providers lock command:
$ terraform -chdir=test-fixtures/lock/simple providers lock -platform=linux_amd64 -platform=darwin_amd64 -platform=darwin_arm64
$ cat test-fixtures/lock/simple/.terraform.lock.hcl
# This file is maintained automatically by "terraform init".
# Manual edits may be lost in future updates.
provider "registry.terraform.io/hashicorp/null" {
version = "3.1.1"
constraints = "3.1.1"
hashes = [
"h1:71sNUDvmiJcijsvfXpiLCz0lXIBSsEJjMxljt7hxMhw=",
"h1:Pctug/s/2Hg5FJqjYcTM0kPyx3AoYK1MpRWO0T9V2ns=",

]
}
When updating provider version, the lock file must also be updated:
$ tfupdate provider null -v 3.2.1 ./test-fixtures/lock/simple/
$ cat test-fixtures/lock/simple/main.tf
terraform {
required_providers {
null = {
source = "hashicorp/null"
version = "3.2.1"
}
}
}
You can update the lock file by the tfupdate lock command without Terraform CLI:
$ tfupdate lock --platform=linux_amd64 --platform=darwin_amd64 --platform=darwin_arm64 ./test-fixtures/lock/simple/
Note that unlike the terraform providers lock command, the --platform flag requires two hyphens.
$ cat test-fixtures/lock/simple/.terraform.lock.hcl
# This file is maintained automatically by "terraform init".
# Manual edits may be lost in future updates.
provider "registry.terraform.io/hashicorp/null" {
version = "3.2.1"
constraints = "3.2.1"
hashes = [
"h1:FbGfc+muBsC17Ohy5g806iuI1hQc4SIexpYCrQHQd8w=",

The tfupdate lock command parses the required_providers block in your configuration, downloads provider packages and calculates hash values under the hood. The most important point is that it caches calculated hash values in memory, which gives us a huge performance advantage when updating multiple directories at once using the -r (--recursive) option.
To skip terraform init, we assume that all dependencies are pinned to a specific version in the required_providers block of the root module. Note that version constraint expressions or indirect dependencies via modules are not supported and ignored.
If you integrate tfupdate with your favorite CI or job scheduler, you can check the latest release daily and create a Pull Request automatically.
An example for tfupdate with CircleCI is available:
