+description: "Learn how to fetch secrets from Infisical with Packer using a data source"
+---
+
+This guide demonstrates how to use the Infisical Packer plugin to fetch secret data using a data source. The Packer plugin supports both [Infisical Cloud](https://app.infisical.com) and [self-hosted instances of Infisical](https://infisical.com/docs/self-hosting/overview).
+
+## Prerequisites
+
+Before you begin, make sure you have:
+
+- [Packer](https://developer.hashicorp.com/packer/install) installed
+- An Infisical account with access to a project
+- Basic understanding of Packer
+
+## Project Setup
+
+### Configure Provider
+
+First, specify the Infisical provider in your Packer configuration:
+
+```hcl
+packer {
+  required_plugins {
+    infisical = {
+      source  = "github.com/infisical/infisical"
+      version = ">=0.0.1"
+    }
+  }
+}
+```
+
+### Authentication
+
+Using a Machine Identity, you can authenticate with [Universal Auth](https://infisical.com/docs/documentation/platform/identities/universal-auth).
+
+```hcl
+data "infisical-secrets" "dev-secrets" {
+  folder_path = "/"
+  env_slug    = "dev" # The environment to list secrets from (e.g. dev, staging, prod)
+  project_id  = "00000000-0000-0000-0000-000000000000"
+  host        = "https://app.infisical.com" # Optional for cloud, required for self-hosted
+
+  universal_auth {
+    client_id = "00000000-0000-0000-0000-000000000000"
+    client_secret = "..." # Optional if using INFISICAL_UNIVERSAL_AUTH_CLIENT_SECRET env variable
+  }
+}
+```

+
+## Using Secrets in Packer
+
+You're able to fetch secrets from Infisical using the `infisical-secrets` Data Source:
+
+```hcl
+# Fetch all secrets from a folder
+data "infisical-secrets" "dev-secrets" {
+  folder_path = "/"
+  env_slug    = "dev"
+  project_id  = "00000000-0000-0000-0000-000000000000"
+
+  universal_auth {
+    ...
+  }
+}
+
+locals {
+  secrets = data.infisical-secrets.dev-secrets.secrets
+}
+
+source "null" "basic-example" {
+  communicator = "none"
+}
+
+build {
+  sources = [
+    "source.null.basic-example"
+  ]
+
+  provisioner "shell-local" {
+    inline = [
+      "echo secret_key: ${local.secrets["SECRET_KEY"].secret_value}",
+    ]
+  }
+}
+```
+
+The `local.secrets` object maps secret keys to [secret objects](https://github.com/Infisical/packer-plugin-infisical/blob/main/docs/datasources/secrets.md#secret-object).
