Overview

Start using HSF by understanding and executing workflows in IDP.

Workflows are the primary way teams interact with HSF. Each workflow is a self-service form in IDP that, when submitted, provisions and manages Harness resources on your behalf using IaCM workspaces under the hood.

What happens when you run a workflow

When a workflow is submitted, HSF:

1. Creates an IaCM workspace mapped to a single Terraform state file to manage the lifecycle of the requested resources.

2. Routes the request through two approval gates before any changes are applied (see Approvals below).

3. Provisions the resources defined by the workflow.

4. Pushes the outputs directly into the IDP catalog entry for that workspace, so the resource is immediately visible and discoverable.

Workspaces for platform-level resources (creating orgs, projects, connectors) live inside the Solutions Factory project. Workspaces for other resources live inside the project they were provisioned into.

Create and Manage IaCM Workspaces Pipeline

Every workflow triggers the Create and Manage IaCM Workspaces pipeline which creates and manages an IaCM workspace. Think of a workspace as the ongoing record of a resource: it holds the Terraform state, the input variables, and the history of every change made to that resource.

Because workspaces maintain ongoing state, you can go back into a workspace at any time, change an input variable, and re-execute to apply the update. You do not need to re-run the workflow from IDP to make changes to an existing resource.

Ephemeral workspaces

If you do not want to maintain ongoing state for a resource, for example for short-lived environments, you can choose to create an ephemeral workspace when submitting the workflow. Ephemeral workspaces are torn down automatically after execution completes. This can be done by going into the YAML of the workflow and setting the variable is_ephemeral to true.

Go to Ephemeral vs Managed Workspaces to decide which setting fits a workflow.

Approvals

Via the Create and Manage IaCM pipeline, every workflow goes through two approval gates before resources are created or modified:

Gate	When it occurs	What the approver sees
Entity creation approval	Before any resources are created	Approval or rejection screen to notify that you have eyes on the changes that are coming
Terraform plan approval	Before the IaCM plan is applied	The full resource diff: exactly what will change

By default, approval notifications are sent by email to members of the HSF Admins group. If your team uses Microsoft Teams or Slack, this can be reconfigured in the notification settings on the HSF Admins user group.

If you want to add an approval to a workflow you can do so by going into the YAML of the workflow and setting the variable requires_approval to true.

The Terraform plan approval shows the full resource diff. Approvers should review this carefully before confirming: this is the last checkpoint before changes are applied to your account.

Default workflows

HSF deploys the following workflows into your account automatically. They are defined in the harness-template-library repository and registered into IDP via the Register Custom IDP Templates pipeline.

Workflow	What it provisions	Persona
Harness Organization Setup	A Harness organization	Platform Engineering / Developer
Harness Project Setup	A project with environments, user groups, and roles	Platform Engineering / Developer
Harness Central Build Farm Setup	CI connectors, secrets, and build infrastructure	Platform Engineering
Deploy Harness SAST & SCA Templates	Security scanning templates and config manager	Platform Engineering
Harness CI Image Factory	A pipeline to mirror and manage CI module images	Developers
Deploy Harness CI Golden Standard Templates	A best-practice CI pipeline template	Platform Engineering
Harness Delegate Image Factory	A custom delegate build pipeline and repository	Platform Engineering

Additional workflows are available in the harness-template-library repository but are not loaded into IDP by default.

Add workflows

The seven default workflows above are deployed regardless of which Harness modules your account has licensed. Additional workflows are available in the harness-template-library repository for specific use cases and modules.

To load additional workflows into IDP:

1. Run the Mirror Harness Official Solutions Factory Repository pipeline to pull the latest version of harness-template-library.

2. Run Register Custom IDP Templates. To load only specific workflows, add the workflow ID to the filter_template input.

For details on what each additional workflow does, check the README files in the harness-template-library repository.
