Chainguard Container for terraform

Terraform is an infrastructure as code tool.

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/terraform:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Compatibility Notes

This image is compatible with upstream terraform image with few exceptions:

• Chainguard's terraform root image is totally compatible with upstream image.
• Chainguard's terraform nonroot image includes a /work directory specifically for the nonroot user, which allows you to mount your Terraform project in that location.

We'll create a simple main.tf file for using chainguard terraform image.

terraform {
  required_providers {
    random = {
      source = "hashicorp/random"
    }
  }
}

provider "random" {}
resource "random_string" "random" {
  length = 16
}

output "random" {
  value = random_string.random.result
}

Save this file as main.tf in your current working directory.

We'll now use chainguard terraform image to initialize the plugins and create the resource.

$ docker run --rm -v $(pwd):/test -w /test cgr.dev/chainguard/terraform:latest init
Initializing the backend...
Initializing provider plugins...
- Finding latest version of hashicorp/random...
- Installing hashicorp/random v3.6.3...
- Installed hashicorp/random v3.6.3 (signed by HashiCorp)
Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

Once our plugins are initialized, we'll go ahead and create the resource.

$ docker run --rm -v $(pwd):/test -w /test cgr.dev/chainguard/terraform:latest apply -auto-approve

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # random_string.random will be created
  + resource "random_string" "random" {
      + id          = (known after apply)
      + length      = 16
      + lower       = true
      + min_lower   = 0
      + min_numeric = 0
      + min_special = 0
      + min_upper   = 0
      + number      = true
      + numeric     = true
      + result      = (known after apply)
      + special     = true
      + upper       = true
    }

Plan: 1 to add, 0 to change, 0 to destroy.

Changes to Outputs:
  + random = (known after apply)
random_string.random: Creating...
random_string.random: Creation complete after 0s [id=PbPn(n:POB5tuPLn]

Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

Outputs:

random = "PbPn(n:POB5tuPLn"

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a development, or -dev, variant.

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
