Self-Managed Platform (SMP)

beta status

IaCM is available on the Self-Managed Platform (SMP) as an early Beta feature. While generally available for certain use cases, IaCM on SMP has a few important caveats:

  • Cost estimation is not currently supported.
  • Airgapped environments may require additional configuration to access providers and modules.

Before You Begin​

Make sure your SMP deployment is installed with the latest version of the Helm chart. Follow the SMP installation instructions.

You’ll also need:

  • A valid IaCM Enterprise or Trial license.
  • Access to your Harness deployment values.
  • Ability to set feature flags and override container images.

Go to SMP basic configuration or contact Harness Support for help retrieving your prerequisites.

Enable IaCM in values.yaml​

In your values.yaml, add the following to enable the IaCM module:

global:
  iacm:
    enabled: true

Update Your License​

Replace your existing license with one that includes IaCM (Enterprise or Trial). Update this block in your values.yaml:

global:
  ng: <insert your new license string>

You can request a new license from your Harness support representative.

Add Required Feature Flags​

Include the following feature flags to enable IaCM capabilities. These may become default in future releases.

platform:
  harness-manager:
    featureFlags:
      ADDITIONAL: "IACM_CLONE_SUBMODULES,IACM_WORKSPACE_SHA_CLONE,IACM_ENABLE_SSH_MODULE_REGISTRY,IACM_ENABLE_DEFAULT_PIPELINES,IACM_ENABLE_MODULE_REGISTRY"

Use a Custom Image for IaCM Steps (Airgapped workaround)​

If your environment blocks external network access, the default pipeline step images may fail when trying to download your OpenTofu or Terraform binary.

To resolve this:

  1. Build a custom version of the plugins/harness_terraform image with the required terraform binary embedded.
  2. Follow the steps in custom images to configure the iacm-manager to use your image.

Next Steps​

Once your SMP deployment is configured, return to the IaCM Get Started guide to connect a repo, create a workspace, and build your first pipelines.
