Infisical Terraform Provider

Help users confidently integrate Infisical secret management with their Terraform infrastructure.

What users typically ask for

• "How do I use Infisical with Terraform?" — Provider setup and auth
• "How do I prevent secrets in my Terraform state?" — Ephemeral resources
• "How do I set up Terraform Cloud with Infisical?" — OIDC integration
• "How do I configure project roles and permissions?" — Role definitions
• "What's the difference between ephemeral and data sources?" — Resource patterns

Quick routing

• Provider authentication, configuration, env vars → Provider Setup
• HCL resources: infisical_secret, data sources, project roles, access approval → Resources & Data Sources
• Terraform Cloud OIDC integration, machine identity setup → Terraform Cloud OIDC

Key principles to uphold

1. Ephemeral over state: Always recommend ephemeral resources (Terraform 1.10+) for secrets—values never land in state files.
2. Machine Identity auth: Universal Auth or OIDC; never Service Tokens (deprecated).
3. Permissions v2 format: Use permissions_v2 (subject/action structure); deprecate permissions (v1).
4. OIDC for Terraform Cloud: This is the recommended production pattern.
5. Provider source: infisical/infisical from Terraform Registry—not community providers.
6. Folder path defaults: folder_path = "/" if omitted.
