Overview

While Miku Miku Beam doesn’t include a pre-built Dockerfile in the repository, it’s designed to be Docker-ready and can be easily containerized for deployment. This guide will walk you through creating and deploying MMB in a Docker container.

​
Creating a Dockerfile

​
Multi-stage Dockerfile

Create a Dockerfile in the project root with the following content: 
# Build stage for web client
FROM node:18-alpine AS web-builder
WORKDIR /app/web-client
COPY web-client/package*.json ./
RUN npm install --no-audit --no-fund
COPY web-client/ ./
RUN npm run build

# Build stage for Go binaries
FROM golang:1.21-alpine AS go-builder
WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download
COPY . .
RUN mkdir -p bin/web-client
COPY --from=web-builder /app/web-client/dist/public/* bin/web-client/
RUN go build -o bin/mmb-server ./cmd/mmb-server
RUN go build -o bin/mmb-cli ./cmd/mmb-cli

# Final runtime stage
FROM alpine:latest
RUN apk --no-cache add ca-certificates
WORKDIR /app

# Copy binaries and web assets
COPY --from=go-builder /app/bin/mmb-server /app/mmb-server
COPY --from=go-builder /app/bin/mmb-cli /app/mmb-cli
COPY --from=go-builder /app/bin/web-client /app/bin/web-client

# Create data directory for configuration
RUN mkdir -p /app/data

# Expose the server port
EXPOSE 3000

# Run the server
CMD ["/app/mmb-server"]

​
Docker Compose Setup

Create a docker-compose.yml file for easier deployment: 
version: '3.8'

services:
  mmb-server:
    build:
      context: .
      dockerfile: Dockerfile
    container_name: miku-miku-beam
    ports:
      - "3000:3000"
    volumes:
      - ./data:/app/data
      - ./config.toml:/app/config.toml:ro
    environment:
      - LOG_FORMAT=json
      - ALLOW_NO_PROXY=false
    restart: unless-stopped
    networks:
      - mmb-network

networks:
  mmb-network:
    driver: bridge

​
Building the Image

1

Build with Docker

Build the Docker image directly:
docker build -t miku-miku-beam:latest .
2

Or build with Docker Compose

Build using Docker Compose:
docker-compose build

​
Configuration Files

Before running the container, prepare the required configuration files:
1

Create data directory

mkdir -p data
2

Create proxies.txt

Add your proxy list (one per line):
cat > data/proxies.txt <<EOF
http://proxy1.example.com:8080
http://user:pass@proxy2.example.com:3128
socks5://proxy3.example.com:1080
EOF
Proxy format supports:
  • protocol://user:password@host:port (with authentication)
  • protocol://host:port
  • host:port (defaults to HTTP)
  • host (defaults to port 8080)
3

Create uas.txt

Add user agent strings (one per line):
cat > data/uas.txt <<EOF
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36
Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36
EOF
4

Create config.toml (optional)

Override default configuration:
proxies_file = "data/proxies.txt"
user_agents_file = "data/uas.txt"
server_port = 3000
allowed_origin = "http://localhost:5173"

​
Running the Container

​
Using Docker Run

docker run -d \
  --name miku-miku-beam \
  -p 3000:3000 \
  -v $(pwd)/data:/app/data \
  -e LOG_FORMAT=json \
  -e ALLOW_NO_PROXY=false \
  --restart unless-stopped \
  miku-miku-beam:latest

​
Using Docker Compose

# Start the service
docker-compose up -d

# View logs
docker-compose logs -f

# Stop the service
docker-compose down

​
Environment Variables

​
LOG_FORMAT
string
default:"console"
Log output format. Set to json for structured logging in production
​
ALLOW_NO_PROXY
boolean
default:"false"
Allow running attacks without proxies. Set to true to enable

​
Volume Mounts

Host PathContainer PathPurpose
./data/app/dataProxies and user agents storage
./config.toml/app/config.tomlConfiguration file (optional)

​
Port Mappings

Container PortProtocolPurpose
3000HTTPWeb UI and API

​
Health Checks

Add a health check to your Dockerfile: 
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
  CMD wget --no-verbose --tries=1 --spider http://localhost:3000/attacks || exit 1
Or in docker-compose.yml: 
services:
  mmb-server:
    # ... other config
    healthcheck:
      test: ["CMD", "wget", "--no-verbose", "--tries=1", "--spider", "http://localhost:3000/attacks"]
      interval: 30s
      timeout: 3s
      retries: 3
      start_period: 5s

​
Docker CLI Access

You can also run attacks using the CLI tool inside the container: 
# Execute CLI commands
docker exec -it miku-miku-beam /app/mmb-cli attack http_flood http://example.com

# With custom parameters
docker exec -it miku-miku-beam /app/mmb-cli attack http_bypass http://example.com \
  --duration 120 \
  --delay 100 \
  --packet-size 1024 \
  --threads 8 \
  --verbose

​
Production Optimization

# Use specific versions for reproducibility
FROM node:18.19-alpine AS web-builder
WORKDIR /app/web-client
COPY web-client/package*.json ./
RUN npm ci --only=production --no-audit --no-fund
COPY web-client/ ./
RUN npm run build

FROM golang:1.21-alpine AS go-builder
RUN apk add --no-cache git ca-certificates
WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download && go mod verify
COPY . .
RUN mkdir -p bin/web-client
COPY --from=web-builder /app/web-client/dist/public/* bin/web-client/
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -ldflags='-w -s' \
    -o bin/mmb-server ./cmd/mmb-server
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -ldflags='-w -s' \
    -o bin/mmb-cli ./cmd/mmb-cli

FROM alpine:latest
RUN apk --no-cache add ca-certificates wget
WORKDIR /app
COPY --from=go-builder /app/bin/mmb-server /app/mmb-server
COPY --from=go-builder /app/bin/mmb-cli /app/mmb-cli
COPY --from=go-builder /app/bin/web-client /app/bin/web-client
RUN mkdir -p /app/data && \
    addgroup -g 1000 mmb && \
    adduser -D -u 1000 -G mmb mmb && \
    chown -R mmb:mmb /app
USER mmb
EXPOSE 3000
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
  CMD wget --no-verbose --tries=1 --spider http://localhost:3000/attacks || exit 1
CMD ["/app/mmb-server"]

​
Troubleshooting

Check if the web client was built correctly:
docker exec miku-miku-beam ls -la /app/bin/web-client
If empty, rebuild the image ensuring the web-client build stage completes successfully.
Ensure the data volume is mounted correctly and contains proxies.txt:
docker exec miku-miku-beam cat /app/data/proxies.txt
Or run with ALLOW_NO_PROXY=true to disable proxy requirement.
If using the non-root user setup, ensure proper permissions:
chmod -R 755 data/
