hmtanbir/dragonfly repository overview

⁠Hardened Dragonfly Container Image

A highly secure, hardened, and multi-architecture (amd64 and arm64) Docker image for Dragonfly—a modern, ultra-fast in-memory data store designed as a drop-in replacement for Redis and Memcached.

This image is built using a secure two-stage process. The final runtime image is based on dhi.io/alpine-base:3.24, which is optimized to contain no package managers (such as apk) or extraneous shell utilities (like curl or wget), significantly reducing the container's attack surface.

⁠Features

• Hardened Base: Built on top of a package-manager-less base image.
• Multi-Architecture Support: Built for both linux/amd64 and linux/arm64 (AArch64).
• Lightweight: Contains only the precompiled Dragonfly executable.

⁠Quick Start

Run Dragonfly immediately using Docker:

docker run -d --name dragonfly -p 6379:6379 hmtanbir/dragonfly:latest

To persist data, mount a volume to /data and configure Dragonfly to store snapshots there:

docker run -d \
  --name dragonfly \
  -p 6379:6379 \
  -v dragonfly_data:/data \
  hmtanbir/dragonfly:latest --logtostderr --dir=/data

⁠Using Docker Compose

Create a docker-compose.yml file:

services:
  dragonfly:
    image: hmtanbir/dragonfly:latest
    container_name: dragonfly
    ports:
      - "6379:6379"
    volumes:
      - dragonfly_data:/data
    command: ["--logtostderr", "--dir=/data"]
    restart: unless-stopped

volumes:
  dragonfly_data:

Run with:

docker compose up -d

⁠Configuration Flags

Dragonfly accepts standard Redis-compatible and Dragonfly-specific flags as arguments. For example:

• --dir=/data: Directory to save database snapshots.
• --logtostderr: Route logs to stderr.
• --requirepass=<YOUR_PASSWORD>: Set an authentication password.
