Creating a Production Dockerfile

Create a Dockerfile for production deployment:

# === Build Stage ===
FROM node:20-alpine AS builder
WORKDIR /app
# Install dependencies
RUN apk add --no-cache python3 make g++ cairo-dev jpeg-dev pango-dev giflib-dev
# Clone and build ClearFlask from source
RUN git clone https://github.com/clearflask/clearflask.git . && \
npm ci && \
npm run build && \
npm prune --production
# === Production Stage ===
FROM node:20-alpine
WORKDIR /app
# Install runtime dependencies
RUN apk add --no-cache tini curl
# Copy built application from builder
COPY --from=builder /app/node_modules ./node_modules
COPY --from=builder /app/dist ./dist
COPY --from=builder /app/public ./public
COPY --from=builder /app/package*.json ./
# Create app user
RUN addgroup -g 1001 -S nodejs && \
adduser -S nodejs -u 1001
# Create data directories
RUN mkdir -p /app/uploads /app/data /app/logs && \
chown -R nodejs:nodejs /app
# Copy entrypoint script
COPY entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh
# Use tini to handle signals properly
ENTRYPOINT ["/sbin/tini", "--"]
# Health check
HEALTHCHECK --interval=30s --timeout=10s --start-period=40s --retries=3 \
CMD curl -f http://localhost:3000/health || exit 1
# Expose port
EXPOSE 3000
# Set user
USER nodejs
# Start application
CMD ["node", "dist/server.js"]

Dockerfile Explanation

  • Build stage: Compiles ClearFlask from source with all dependencies
  • Production stage: Lightweight runtime with only production dependencies
  • Data persistence: /app/uploads for file attachments and /app/data for database
  • Non-root user: Runs as nodejs user for security
  • Health checks: Automatic container health monitoring
  • Signal handling: Uses tini for proper signal handling
  • Multi-stage build: Reduces final image size significantly

Create Entrypoint Script

Create entrypoint.sh for initialization:

#!/bin/sh
set -e
echo "Starting ClearFlask initialization..."
# Wait for database if needed
if [ -n "$DATABASE_URL" ]; then
echo "Waiting for database to be ready..."
timeout 30 sh -c 'until nc -z $(echo $DATABASE_URL | sed "s/.*@//g" | cut -d: -f1) $(echo $DATABASE_URL | sed "s/.*://g" | cut -d/ -f1); do sleep 1; done' || true
fi
# Run migrations if needed
if [ "$RUN_MIGRATIONS" = "true" ]; then
echo "Running database migrations..."
npm run migrate || true
fi
echo "ClearFlask startup complete. Starting server..."
# Start the application
exec node dist/server.js

Building the Dockerfile Locally (Optional)

Test the Dockerfile locally:

Terminal window
# Build the Docker image
docker build -t clearflask:latest .
# Run the container locally (for testing only)
docker run -d \
--name clearflask-test \
-p 3000:3000 \
-e NODE_ENV=production \
-v clearflask-uploads:/app/uploads \
-v clearflask-data:/app/data \
clearflask:latest
# Wait for container to start
sleep 10
# Access the application
# http://localhost:3000
