# How to manage Prefect resources using Infrastructure as Code

> Declaratively manage Prefect resources with additional tools

export const HELM = ({name, href}) => <p>You can manage {name} with the <a href={href}>Prefect Helm charts</a>.</p>;

export const home = {
  tf: "https://registry.terraform.io/providers/PrefectHQ/prefect/latest/docs/guides/getting-started",
  cli: "https://docs.prefect.io/v3/api-ref/cli/index",
  api: "https://app.prefect.cloud/api/docs",
  helm: "https://github.com/PrefectHQ/prefect-helm/tree/main/charts"
};

export const TF = ({name, href}) => <p>You can manage {name} with the <a href={href}>Terraform provider for Prefect</a>.</p>;

You can manage many Prefect resources with tools like
[Terraform](https://www.terraform.io/) and [Helm](https://helm.sh/).  These
options are a viable alternative to Prefect's CLI and UI.

## Terraform

<TF name="resources" href={home.tf} />

This documentation represents all Prefect resources that are supported by Terraform.
This Terraform provider is maintained by the Prefect team, and is undergoing active development
to reach [parity with the Prefect API](https://github.com/PrefectHQ/terraform-provider-prefect/milestone/1).

The Prefect team welcomes contributions, feature requests, and bug reports
via our [issue tracker](https://github.com/PrefectHQ/terraform-provider-prefect/issues).

### Terraform Modules

Prefect maintains several Terraform modules to help you get started with common infrastructure patterns:

* [Bucket Sensors for AWS, Azure, and GCP](https://github.com/PrefectHQ/terraform-prefect-bucket-sensor)
* [ECS Worker on AWS Fargate](https://github.com/PrefectHQ/terraform-prefect-ecs-worker)
* [ACI Worker on Azure Container Instances](https://github.com/PrefectHQ/terraform-prefect-aci-worker)

## Pulumi

Prefect does not maintain an official Pulumi package.
However, you can use Pulumi’s terraform-provider to automatically generate a Pulumi SDK from the Prefect Terraform provider.
For details, refer to the [Pulumi documentation on Terraform providers](https://www.pulumi.com/registry/packages/terraform-provider/).

<Tip>
  You will need to be using Pulumi version >= 3.147.0.
</Tip>

In this example, we will use Pulumi to deploy a flow to Prefect.

Prefect recommends using the `uv` for managing Python dependencies.
This example will show you how to set up a Pulumi project using the `uv` toolchain.

<AccordionGroup>
  <Accordion title="Creating a new Pulumi project">
    To create a new Python Pulumi project using the `uv` toolchain, run the following command:

    ```bash  theme={null}
    pulumi new python \
    --yes \
    --generate-only \
    --name "my-prefect-pulumi-project" \
    --description "A Pulumi project to manage Prefect resources" \
    --runtime-options toolchain=uv \
    --runtime-options virtualenv=.venv
    ```

    <Warning>
      Don't name your project any of the following, otherwise you will have package name conflicts:

      * `pulumi`
      * `prefect`
      * `pulumi-prefect`
    </Warning>

    <Info>
      An explanation of the [flags](https://www.pulumi.com/docs/iac/cli/commands/pulumi_new/#options) used:

      * The `--yes` flag skips the interactive prompts and accepts the defaults. You can omit this flag,
        or edit the generated `Pulumi.yaml` file later to customize your project settings.
      * The `--generate-only` just creates a new Pulumi project. It does not create a stack, save config,
        or install dependencies.
      * The `--name` and `--description` flags set the name and description of your Pulumi project.
      * The `--runtime-options toolchain=uv` and `--runtime-options virtualenv=.venv` flags configures
        the Pulumi project to use the `uv` toolchain instead of the default, `pip`.
    </Info>

    To finish setting up your new Pulumi project, navigate to the project directory and install the dependencies:

    ```bash  theme={null}
    pulumi install
    ```
  </Accordion>

  <Accordion title="Using an existing Pulumi project">
    If you already have a Pulumi project, you can switch to the `uv` toolchain by updating
    your `pulumi.yaml` file `runtime` settings as shown below:

    ```yaml Pulumi.yaml theme={null}
    # other project settings...
    runtime:
      name: python
      options:
        toolchain: uv
        virtualenv: .venv
    ```

    This configures your Pulumi project to use the `uv` toolchain and the virtual environment located at `.venv`.

    Run the following to update Pulumi to use the `uv` toolchain:

    ```bash  theme={null}
    pulumi install
    ```
  </Accordion>
</AccordionGroup>

### Managing Resources with Pulumi

To manage resources with Pulumi, add the Prefect Terraform provider to your Pulumi project:

```bash  theme={null}
pulumi package add terraform-provider prefecthq/prefect
```

Optionally, you can specify a specific version, e.g.:

```bash  theme={null}
pulumi package add terraform-provider prefecthq/prefect 2.90.0
```

This will auto-generate a `pulumi-prefect` Python package.
The code will be placed in the `sdks/prefect` directory inside the Pulumi project.

### Example: Deploying a Flow with Pulumi

This simple example shows you how to deploy a flow to Prefect.

```python  theme={null}
import json
import pulumi
import pulumi_prefect as prefect
from prefect.utilities.callables import parameter_schema
from typing import Callable, Any

# Import your flow here
from my_flow import test as example_flow


def generate_openapi_schema_for_flow(flow_obj: Callable[..., Any]) -> str:
    """
    Utility function to generate an OpenAPI schema for a flow's parameters.
    This is used to provide type information for deployments created via Pulumi.
    
    See also:
        * `parameter_schema <https://github.com/PrefectHQ/prefect/blob/main/src/prefect/utilities/callables.py#L331>`_
        * `model_dump_for_openapi <https://github.com/PrefectHQ/prefect/blob/main/src/prefect/utilities/callables.py#L247>`_
    """
    return json.dumps(parameter_schema(flow_obj).model_dump_for_openapi())

# Configure the Provider
provider = prefect.Provider(
    "prefect",
    # endpoint="https://api.prefect.cloud/api/account/<account>/workspace/<workspace>",
    # api_key="<your_api_key>",  # or use pulumi.Config to manage secrets
)

# Register the Flow
flow = prefect.Flow(
    "example-flow",
    name="example-flow",
    tags=["example", "pulumi"],
    opts=pulumi.ResourceOptions(provider=provider)
)

# Create a Deployment resource
deployment = prefect.Deployment(
    "example-deployment",
    name="example-deployment",
    flow_id=flow.id,
    work_pool_name="example-work-pool",
    work_queue_name="default",
    parameters=json.dumps({"foo": "bar"}),
    tags=["example", "pulumi"],
    enforce_parameter_schema=True,
    parameter_openapi_schema=generate_openapi_schema_for_flow(example_flow),
    opts=pulumi.ResourceOptions(provider=provider),

    # specify how to get the flow code to the worker
    # the Deployment resource does not have the same support as `prefect.yaml` for automatically packaging flow code
    # see: https://registry.terraform.io/providers/PrefectHQ/prefect/latest/docs/resources/deployment#deployment-actions

    # option 1: clone the repo at runtime
    # pull_steps = [
    #     {
    #         "type": "git_clone",
    #         "repository": "https://github.com/some/repo",
    #         "branch": "main",
    #         "include_submodules": True,
    #     }
    # ],
    # entrypoint="flow.py:hello_flow",

    # option 2: use a pre-built container image
    # note: you will need to build this image yourself and push it to a registry
    # job_variables = json.dumps({
    #     "image": "example.registry.com/example-repo/example-image:v1"
    # })
)

# Add a schedule to the deployment to run every minute
schedule = prefect.DeploymentSchedule(
    "example-schedule",
    deployment_id=deployment.id,
    active=True,
    cron="0 * * * *",
    timezone="UTC",
    opts=pulumi.ResourceOptions(provider=provider),
)
```

Now you can run `pulumi up` to create the resources in your Prefect workspace.

## Helm

<HELM name="resources" href={home.helm} />

Each Helm chart subdirectory contains usage documentation. There are two main charts:

* The `prefect-server` chart is used to a deploy a Prefect server. This is an alternative to using
  [Prefect Cloud](https://app.prefect.cloud/).
* The `prefect-worker` chart is used to deploy a [Prefect worker](/v3/deploy/infrastructure-concepts/workers).

Finally, there is a `prefect-prometheus-exporter` chart that is used to deploy a Prometheus exporter,
exposing Prefect metrics for monitoring and alerting.
