Terraform provider for various utilities (deep merging, Atmos stack configuration management), and to add additional missing functionality to Terraform

[!TIP]

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform. Works with Github Actions, Atlantis, or Spacelift.

Usage

Here is how to use this provider in your own Terraform code:

terraform {
  required_providers {
    utils = {
      source = "cloudposse/utils"
      version = ">= 1.17.0"
    }
  }
}

See the Docs for additional information.

[!IMPORTANT] In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.

Examples

Here is an example of using this provider:

terraform {
  required_providers {
    utils = {
      source = "cloudposse/utils"
    }
  }
}

locals {
  yaml_data_1 = file("${path.module}/data1.yaml")
  yaml_data_2 = file("${path.module}/data2.yaml")
}

data "utils_deep_merge_yaml" "example" {
  input = [
    local.yaml_data_1,
    local.yaml_data_2
  ]
}

output "deep_merge_output" {
  value = data.utils_deep_merge_yaml.example.output
}

Here are some additional examples:

Developing the Provider

If you wish to work on the provider, you'll first need Go installed on your machine (see Requirements above).

To compile the provider, run go install. This will build the provider and put the provider binary in the $GOPATH/bin directory.

To generate or update documentation, run go generate.

In order to run the full suite of Acceptance tests, run make testacc.

Note: Acceptance tests create real resources, and often cost money to run.

$ make testacc

Testing Locally

You can test the provider locally by using the provider_installation functionality.

For testing this provider, you can edit your ~/.terraformrc file with the following:

provider_installation {
  dev_overrides  {
    "cloudposse/utils" = "/path/to/your/code/github.com/cloudposse/terraform-provider-utils/"
  }

  # For all other providers, install them directly from their origin provider
  # registries as normal. If you omit this, Terraform will _only_ use
  # the dev_overrides block, and so no other providers will be available.
  direct {}
}

With that in place, you can build the provider (see above) and add a provider block:

required_providers {
    utils = {
      source = "cloudposse/utils"
    }
  }

Then run terraform init, terraform plan and terraform apply as normal.

$ terraform init

Warning: Provider development overrides are in effect

The following provider development overrides are set in the CLI configuration:
 - cloudposse/utils in /path/to/your/code/github.com/cloudposse/terraform-provider-utils

The behavior may therefore not match any released version of the provider and
applying changes may cause the state to become incompatible with published
releases.

Terraform Plugins - Terraform is logically split into two main parts: Terraform Core and Terraform Plugins. Each plugin exposes an implementation for a specific service, such as the AWS provider or the cloud-init provider.
