How to Build a Production CI/CD Pipeline with GitHub Actions and Docker Under 50MB (2026 Guide)
Step-by-step architecture guide for modern DevOps engineers to automate testing, build multi-arch containers, and deploy to Kubernetes with zero downtime.
Deploying code manually via SSH or handling brittle server configurations is the #1 cause of cloud downtime and security incidents in production software.
The Architecture Blueprint
A production-grade delivery pipeline consists of 4 isolated stages: Quality Gate, Multi-Arch Buildx Container Compilation, Hardened Alpine Runtime (<50MB) executing under dedicated non-root UID 1001, and Zero-Downtime Kubernetes Rolling Rollout.
FROM node:20-alpine AS runner
WORKDIR /app
ENV NODE_ENV=production
RUN addgroup --system --gid 1001 nodejs && adduser --system --uid 1001 appuser
COPY --from=builder --chown=appuser:nodejs /app/dist ./dist
USER appuser
EXPOSE 3000
CMD ["node", "dist/index.js"]Open Source vs. Pro
