# Infisical Terraform Provider

The Infisical Terraform Provider enables infrastructure-as-code management of secrets, identities, projects, and integrations within the Infisical secrets management platform. It provides comprehensive resources for creating and managing secrets, machine identities with various authentication methods (Universal Auth, AWS IAM, Azure, GCP, Kubernetes, OIDC), projects with custom environments and roles, secret syncs to external services, dynamic secrets, KMS keys, and certificate management.

The provider supports both Infisical Cloud (app.infisical.com) and self-hosted instances. Authentication is handled through machine identities using Universal Auth, AWS IAM Auth, Kubernetes Auth, OIDC Auth, or Token Auth. Core functionality includes reading and writing secrets, managing access controls through approval policies, syncing secrets to cloud providers (AWS, Azure, GCP) and CI/CD platforms (GitHub, GitLab, CircleCI), rotating credentials automatically, and issuing PKI certificates.

## Provider Configuration

Configure the Infisical provider with authentication credentials. Universal Auth is the most common method using client ID and secret.

```terraform
terraform {
  required_providers {
    infisical = {
      source = "infisical/infisical"
      # version = "<latest version>"
    }
  }
}

provider "infisical" {
  host = "https://app.infisical.com" # Default, only change for self-hosted
  auth = {
    # Optional: scope session to a sub-organization
    # organization_slug = "my-sub-org"
    universal = {
      client_id     = var.infisical_client_id
      client_secret = var.infisical_client_secret
    }
  }
}

# Alternative: Kubernetes Auth (for pods running in Kubernetes)
provider "infisical" {
  host = "https://app.infisical.com"
  auth = {
    kubernetes = {
      identity_id = "your-machine-identity-id"
      # Uses /var/run/secrets/kubernetes.io/serviceaccount/token by default
    }
  }
}

# Alternative: AWS IAM Auth (for AWS workloads)
provider "infisical" {
  host = "https://app.infisical.com"
  auth = {
    aws_iam = {
      identity_id = "your-machine-identity-id"
    }
  }
}
```

## infisical_secrets Data Source

Fetch all secrets from a specific environment and folder path in an Infisical project. Returns a map of secret names to their values and metadata.

```terraform
data "infisical_secrets" "app_secrets" {
  env_slug     = "prod"
  workspace_id = "507f1f77bcf86cd799439011"  # Project ID
  folder_path  = "/backend"
}

# Access individual secret value
output "database_url" {
  value     = data.infisical_secrets.app_secrets.secrets["DATABASE_URL"].value
  sensitive = true
}

# Access secret comment/metadata
output "api_key_comment" {
  value = data.infisical_secrets.app_secrets.secrets["API_KEY"].comment
}

## Summary

The Infisical Terraform Provider is ideal for organizations implementing secrets management as code, enabling GitOps workflows for secret lifecycle management. Common use cases include bootstrapping new projects with standardized secret structures, provisioning machine identities for CI/CD pipelines, automating secret rotation schedules, syncing secrets to cloud providers and deployment targets, and enforcing approval workflows for production secret changes. The provider integrates seamlessly with existing Terraform infrastructure code, allowing secrets to be managed alongside the resources that consume them.

Integration patterns typically involve creating a central secrets project, defining machine identities with appropriate authentication methods (Universal Auth for general use, AWS IAM Auth for AWS workloads, Kubernetes Auth for Kubernetes pods), assigning identities to projects with custom roles, and setting up secret syncs to external systems like AWS Secrets Manager, Azure Key Vault, or GitHub Actions. For sensitive environments, approval policies ensure human review before changes take effect. The ephemeral resources feature (Terraform 1.10+) is particularly valuable for keeping sensitive credentials out of Terraform state entirely, making it safer to use secrets for configuring database providers, cloud APIs, and other sensitive connections.
