Doppler secret adapter for Fujin

Fujin Secrets - Doppler

Doppler secret adapter for Fujin deployment tool.

Installation

pip install fujin-secrets-doppler

Or with uv:

uv pip install fujin-secrets-doppler

Prerequisites

Download and install the Doppler CLI and sign in to your account.

Move to your project root directory and run doppler setup to configure your project.

Configuration

Add the following to your fujin.toml file:

[secrets]
adapter = "doppler"

Usage

In your environment file (.env or configured via envfile in fujin.toml), prefix secret values with $:

DEBUG=False
AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY

The $ sign indicates to Fujin that it is a secret that should be resolved using the configured adapter.

How it Works

The adapter:

1. Uses the Doppler CLI configuration from your project setup
2. Resolves all secrets concurrently using doppler run --command "echo $<name>"
3. Returns the resolved environment variables
