Authelia API

A Go-based REST API and management layer that sits alongside an Authelia LXC on Proxmox. Provides a "Source of Truth" in SQLite, handles bulk user onboarding via JSON, and automates synchronization of the Authelia users_database.yml file.

Features

• Sovereign Bootstrap: Automatically imports existing Authelia users on first run
• Bulk User Management: Create multiple users via JSON API with automatic password generation
• Real-time Sync: SQLite changes automatically sync to Authelia's YAML configuration
• SMTP Onboarding: Send welcome emails using Authelia's SMTP configuration
• Secure API: Bearer token authentication with bcrypt hashing
• Drop-in Deployment: Runs alongside existing Authelia installation

Installation

Docker Deployment (Recommended)

A combined container with both Authelia and Authelia-API is available on Docker Hub:

# Create config directory with your Authelia configuration
mkdir -p config data certs
# Copy and edit the example config:
#   docker/configuration.yml.example → config/configuration.yml
#   Set secrets, domains, and other settings.

# Pull and start
docker compose up -d

Port	Service
9091	Authelia web portal
8080	Authelia-API (user management API)

First-time authentication: The container creates an admin user automatically on startup by reading the session.secret from your Authelia config. Whatever value you set for session.secret in configuration.yml becomes your initial bearer token — there is nothing to fetch. For example:

curl -H "Authorization: Bearer your-session-secret-value" http://localhost:8080/api/health

Authelia configuration reference: The example file at docker/configuration.yml.example covers the essentials, but Authelia has many more options. See the official Authelia configuration docs for details on secrets, domains, authentication backends, and access control rules.

Bare Metal (Quick Installation)

Runs the install script directly on the host alongside an existing Authelia installation:

curl -fsSL https://git.lohmar.co.uk/cclohmar/autehlia-api/raw/branch/main/install-authelia-api.sh | sudo bash

Manual Installation

1. Download the binary:

   curl -fsSL -o authelia-api https://git.lohmar.co.uk/cclohmar/autehlia-api/raw/branch/main/authelia-api
   chmod +x authelia-api
   

2. Run the installer:

   sudo ./install-authelia-api.sh
   

Development Installation

For building from source, see the src/README.md file.

Note for local development: When installing from a cloned repository, set the environment variable to use the local binary:

AUTHELIA_API_DEVELOPMENT_MODE=true sudo ./install-authelia-api.sh

Quick Start

Get your bearer token:

• Docker: The token is whatever you set as session.secret in your configuration.yml

  curl -H "Authorization: Bearer your-session-secret-value" http://localhost:8080/api/health
  

• Bare metal: Read it from your existing Authelia configuration

  grep -A2 "session:" /opt/authelia/configuration.yml | grep "secret:" | awk '{print $2}'
  curl -H "Authorization: Bearer THAT_VALUE" http://127.0.0.1:8080/api/health
