Foreman Terraform Provider:

Terraform provider to interact with Foreman.

This project is a component of Project Argo.

Project Info

This project is developed, owned, and maintained by the SRE - Orchestration pod at Wayfair.

This repository uses mkdocs for documentation and dep for dependency management. Dependencies are tracked as part of the repository.

Foreman Requirements:

Foreman Smart proxies will need to be provisioned with the Foreman BMC plugin and have the ipmitool installed.


Follow the setup instructions provided on the install sections of their respective websites. Windows environments should have a *nix-style terminal emulator installed such as Cygwin to be compatible with the makefile.

Provider / Repository Setup

After installing and configuring the toolchain listed in the Requirements section:

  1. Clone the repository with ssh:

    $ mkdir -p "${GOPATH}/src/"
    $ cd "${GOPATH}/src/"
    $ git clone
  2. Enter the root directory of the project and install the provider:

    $ cd "${GOPATH}/src/"
    $ make install

    The install target will run a codebase vet and lint check, compile the binary, and then move the binary to the Terraform plugins directory.

    NOTE: See the Third-party Plugins section on Terraform's website over here

  3. Initialize Terraform and verify the provider is recognized by terraform:

    $ cd ./examples/verify_provider
    $ terraform init
    $ terraform --version

    You should see the foreman provider in the output like in the listing below. Other providers may be listed if you have already configured Terraform. Your version info may be different depending on the version of Terraform you installed as part of the Requirements.

    Terraform v0.11.3
    + provider.foreman (unversioned)

    NOTE: Some builds of Terraform will require subdirectories underneath terraform.d/plugins organized by operating system and architecture. If this is the case, create the directory (if it doesn't exist) and then place the plugin within that directory. If your terraform init failed with the following message Provider "foreman" not available for installation, then this is likely the case. Read the error message and create the correct subdirectory. For 64 bit Windows, this will be terraform.d/plugins/windows_amd64. So in step 2, confirm the provider binary is located at terraform.d/plugins/windows_amd64/terraform-provider-foreman.exe and then try step 3 again.


This repository uses mkdocs for documentation. Repository documentation can be found in the doc directory. Follow the installation instructions on mkdocs to get started.

The Makefile exposes a godoc target which can be used to generate and save the project's Godoc to the local filesystem in docs/godoc. These pages are used by mkdocs to generate the full project documentation. The godoc target only saves the necessary package documentation for this repository and does save the entire webroot.

The mkdocs configuration and associated markdown is auto-generated for the provider using the autodoc package from the utility repository. The autodoc tool uses text templates defined in templates and the schema definitions in the provider to generate all the necessary mkdocs files and resources. The autodoc command is located in cmd/autodoc/main.go.

To generate and view the entire repository and in-depth provider documentation:

The documentation can then be viewed by accessing localhost in your favorite browser or viewport.

Cleaning up the generated godoc and mkdocs can be done with the clean-godoc and clean-mkdoc targets.

NOTE: When developing, it may be useful to setup terraform logging. A full list of Terraform environment variables can be found here. At minimum, it is advised to set the log level to DEBUG like so:

MacOS / Linux

$ export TF_LOG=DEBUG


> $env:TF_LOG = "DEBUG"

The provider is set to log to the file terraform-provider-foreman.log with all Foreman provider specific log messages sent to this file. When the provider is executed, it will create the provider log file in the current working directory (if it does not exist). If the log file already exists, then the logs are appended to the existing file. In the case the provider cannot create/open the desired log file, the provider defaults to sending log messages to stderr.

The provider uses a level-based logging module that extends the golang stdlib log package. When the log level is set to a verbosity threshold, only log messages of that verbosity and higher are sent to the output file.

From most verbose to least verbose:

Log Level Description
DEBUG Intermediate calculations, values. Useful when debugging.
TRACE Function enter/exit notifications
INFO Notifications - not related to suspicious behavior or errors
WARNING Suspcious or error behavior, but the system was able to recover or default/degrade gracefully
ERROR Behavior that causes the program execution to stop
NONE Do not log any output

The provider's log level defaults to INFO, meaning INFO, WARNING, and ERROR messages are committed to the log file, DEBUG and TRACE are ignored. The log level can be overridden by either setting the provider_loglevel attribute in the provider block of the Terraform module, or by setting the environment variable FOREMAN_PROVIDER_LOGLEVEL. If both values are set, provider_loglevel takes precedence. You can also override the Foreman provider's log file using the FOREMAN_PROVIDER_LOGFILE environment variable. A value of - preserves the stdlib log behavior and outputs to the stdlog stream.


Terraform module

provider "foreman" {
  provider_loglevel = "DEBUG"
  provider_logfile  = "terraform-provider-foreman.log"

MacOS / Linux

$> export FOREMAN_PROVIDER_LOGFILE="terraform-provider-foreman.log"


> $env:FOREMAN_PROVIDER_LOGFILE = "terraform-provider-foreman.log"

Using the Provider:

An example of of usage of this provider is included in this repository under ./examples. See the examples for more information.
