Automated Deployments: Zero-Downtime Releases with GitHub Actions & Docker

Containerization Strategy Packaging enterprise applications requires robust Docker multi-stage configurations. This cuts overall deployment image sizes by removing dev dependencies from final production runs.

Multi-Stage Build Configurations Below is a secure, light-weight container design configuration for Node/Next applications:

# Stage 1: Dependency resolution
FROM node:20-alpine AS deps
WORKDIR /app
COPY package.json bun.lockb ./

# Stage 2: Production builder FROM node:20-alpine AS builder WORKDIR /app COPY --from=deps /app/node_modules ./node_modules COPY . . RUN npm install -g bun && bun run build

# Stage 3: Runner runtime FROM node:20-alpine AS runner WORKDIR /app ENV NODE_ENV=production COPY --from=builder /app/public ./public COPY --from=builder /app/.next/standalone ./.next/standalone CMD ["node", ".next/standalone/server.js"] ```
