LibreChat can be deployed using Docker with a single container that includes both the backend API and frontend client. This is the simplest deployment method for getting started quickly.

​
Prerequisites

Before deploying LibreChat with Docker, ensure you have:
  • Docker Engine 20.10 or later
  • Docker Compose (optional, for multi-container setup)
  • At least 2GB of available RAM
  • 10GB of free disk space

​
Dockerfile Overview

LibreChat uses a multi-stage Dockerfile optimized for production deployment. The build process includes: 
# Base node image
FROM node:20-alpine AS node

# Install jemalloc for memory optimization
RUN apk add --no-cache jemalloc
RUN apk add --no-cache python3 py3-pip uv

# Set environment variable to use jemalloc
ENV LD_PRELOAD=/usr/lib/libjemalloc.so.2

# Add uv for extended MCP support
COPY --from=ghcr.io/astral-sh/uv:0.9.5-python3.12-alpine /usr/local/bin/uv /usr/local/bin/uvx /bin/

# Set configurable max-old-space-size with default
ARG NODE_MAX_OLD_SPACE_SIZE=6144

WORKDIR /app

# Copy package files
COPY package.json package-lock.json ./
COPY api/package.json ./api/package.json
COPY client/package.json ./client/package.json
COPY packages/data-provider/package.json ./packages/data-provider/package.json
COPY packages/data-schemas/package.json ./packages/data-schemas/package.json
COPY packages/api/package.json ./packages/api/package.json

# Install dependencies
RUN npm ci --no-audit

# Copy application code
COPY . .

# Build frontend with configurable memory
RUN NODE_OPTIONS="--max-old-space-size=${NODE_MAX_OLD_SPACE_SIZE}" npm run frontend

# Node API setup
EXPOSE 3080
ENV HOST=0.0.0.0
CMD ["npm", "run", "backend"]

​
Building the Image

1

Clone the Repository

First, clone the LibreChat repository:
git clone https://github.com/danny-avila/LibreChat.git
cd LibreChat
2

Build the Docker Image

Build the Docker image with default settings:
docker build -t librechat .
To customize the Node.js memory allocation:
docker build --build-arg NODE_MAX_OLD_SPACE_SIZE=8192 -t librechat .
3

Configure Environment Variables

Create a .env file with your configuration:
cp .env.example .env
Edit the .env file with your API keys and configuration:
# MongoDB Connection
MONGO_URI=mongodb://mongodb:27017/LibreChat

# Server Configuration
HOST=0.0.0.0
PORT=3080

# Authentication
JWT_SECRET=your-secret-key
JWT_REFRESH_SECRET=your-refresh-secret
CREDS_KEY=your-creds-key
CREDS_IV=your-creds-iv

# Meilisearch
MEILI_HOST=http://meilisearch:7700
MEILI_MASTER_KEY=your-meili-key

# API Keys
OPENAI_API_KEY=your-openai-key
ANTHROPIC_API_KEY=your-anthropic-key
4

Run the Container

Run LibreChat with required dependencies:
docker run -d \
  --name librechat \
  -p 3080:3080 \
  --env-file .env \
  -v ./images:/app/client/public/images \
  -v ./uploads:/app/uploads \
  -v ./logs:/app/logs \
  librechat

​
Port Configuration

LibreChat exposes the following port:
PortProtocolDescription
3080HTTPMain application server (API + Frontend)
The default port is 3080. You can change this by setting the PORT environment variable and adjusting the EXPOSE directive in the Dockerfile.

​
Volume Mounts

The following directories should be mounted as volumes for persistent data:
Host PathContainer PathPurpose
./images/app/client/public/imagesUser-uploaded images
./uploads/app/uploadsFile uploads
./logs/app/logsApplication logs
Always mount these directories to persist data across container restarts. Without volume mounts, all uploaded files and logs will be lost when the container stops.

​
Environment Variables

Key environment variables for Docker deployment:

​
Required Variables

# Application Host
HOST=0.0.0.0

# MongoDB Connection
MONGO_URI=mongodb://mongodb:27017/LibreChat

# Authentication Secrets
JWT_SECRET=your-jwt-secret
JWT_REFRESH_SECRET=your-refresh-secret
CREDS_KEY=your-creds-key
CREDS_IV=your-creds-iv

​
Optional Variables

# Meilisearch Configuration
MEILI_HOST=http://meilisearch:7700
MEILI_MASTER_KEY=your-master-key

# RAG API Configuration
RAG_PORT=8000
RAG_API_URL=http://rag_api:8000

# Node.js Memory
NODE_OPTIONS=--max-old-space-size=6144

​
Using Pre-built Images

Instead of building locally, you can use official pre-built images: 
docker pull registry.librechat.ai/danny-avila/librechat-dev:latest

docker run -d \
  --name librechat \
  -p 3080:3080 \
  --env-file .env \
  -v ./images:/app/client/public/images \
  -v ./uploads:/app/uploads \
  -v ./logs:/app/logs \
  registry.librechat.ai/danny-avila/librechat-dev:latest

​
Health Checks

LibreChat provides a health check endpoint at /health (port 3080). You can configure Docker health checks: 
docker run -d \
  --name librechat \
  --health-cmd="curl -f http://localhost:3080/health || exit 1" \
  --health-interval=30s \
  --health-timeout=10s \
  --health-retries=3 \
  -p 3080:3080 \
  librechat

​
Memory Optimization

LibreChat uses jemalloc for improved memory management. The Dockerfile includes: 
# Install jemalloc
RUN apk add --no-cache jemalloc

# Set environment variable to use jemalloc
ENV LD_PRELOAD=/usr/lib/libjemalloc.so.2
jemalloc reduces memory fragmentation and improves performance under high load. This is automatically configured in the Docker image.

​
MCP Support

The Docker image includes uv for Model Context Protocol (MCP) support: 
COPY --from=ghcr.io/astral-sh/uv:0.9.5-python3.12-alpine /usr/local/bin/uv /usr/local/bin/uvx /bin/
RUN uv --version
This enables LibreChat to work with MCP servers and tools.

​
Troubleshooting

​
Container Won’t Start

  1. Check logs: 
    docker logs librechat
  2. Verify environment variables: 
    docker exec librechat env

​
Out of Memory Errors

Increase Node.js memory allocation: 
docker run -d \
  --name librechat \
  -e NODE_OPTIONS="--max-old-space-size=8192" \
  -p 3080:3080 \
  librechat

​
Permission Issues

Ensure mounted volumes have correct permissions: 
sudo chown -R 1000:1000 ./images ./uploads ./logs
