A Packer plugin for provisioning with Terraform (local)

Packer Plugin Terraform

Inspired by Megan Marsh's talk https://www.hashicorp.com/resources/extending-packer I bit the bullet and started making my own ill advised provisioner for Terraform.

Usage

packer {
  required_plugins {
    terraform = {
      version = "= 0.0.7"
      source = "github.com/servian/terraform"
    }
  }
}

source "docker" "test_server" {
  commit = true
  image  = "amazonlinux:2"
}

build {
  sources = ["source.docker.test_server"]

  provisioner "terraform" {
    code_path       = "./tfcode"
    prevent_sudo    = "true"
    variable_string = jsonencode({
        consul_server_node = false
    })
    version = "1.0.0"
  }
}

parameters

• version(string) - the version of Terraform to install
• code_path(string) - (required) the path to the terraform code
• run_command(string) - override the command to run Terraform
• install_command(string) - override the command to run Terraform
• staging_dir(string) - override the remote path to stage the code.
• variables(map(String, String)) - set terraform variables into a terraform.auto.tfvars file

packer-plugin-terraform's Issues

Windows provisioning

Currently this provider makes some assumptions that it is running on linux guests. It should also work on Windows too.
</note to self>

Add this to the packer community providers list.

TODO: create a PR on the Packer repo and add this repo's url to the big json file.

Leverage HC-install for finding and downloading latest Terraform

Still pending on HC-install PR4 we might be able to leverage HC-install for finding and downloading latest Terraform.

Update for HCL based templates

(Note to self?) I think there needs to be a small update to the provisioner interface to support being used with the new Packer 1.5 HCL templates.

Dynamically pull latest TF build if unspecified

Rather than (cough) hardcoding, it should dynamically pull latest TF build if unspecified in the config.
