Hardened DevOps Engineering Practices

Config files generated by this tool follow battle-tested container and server guidelines: non-root execution users, multi-stage builds to minimize image attack surfaces, TLS 1.3 encryption, and modern HTTP security headers.

Non-Root Containers

All Dockerfiles configure dedicated system user accounts (e.g. USER nextjs) to prevent container escape vulnerabilities.

Multi-Stage Caching

Isolates source builds and dependencies into separate layers, resulting in lightweight, high-performance production artifacts.

SSL & Security Headers

Nginx templates include automated Let's Encrypt path integration, HSTS, frame options, and gzip compression.
