Deploying standard Next.js images with full node_modules bloats Docker overlay2 layers past 1.8 GB per deploy and idles above 500 MB RAM per container.
Enabling Next.js standalone output in Dokploy, sharing one tuned PostgreSQL 17 + Redis 7 instance across internal dokploy-network aliases, and capping V8 heaps packs 8 to 10 production SaaS apps comfortably onto an 8 GB or 16 GB NVMe VPS. (DokployHub BP-01)
In this BP-01 runbook on DokployHub, we pair interactive cgroup RAM sizing, browser-persisted checklist gates, and copyable configuration snippets grounded in 2026-11-12 public vendor rate cards.
DokployHub BP-01 Architecture & Hardening Checklist
-
Enable output: "standalone" inside next.config.mjs so Nixpacks/Railpack or multi-stage Dockerfiles ship only traced server dependencies—slashing image size by 78% and cold-start time under 350ms.
Confirm gate #1 in your BP-01 staging environment.
-
Consolidate internal databases: create one PostgreSQL 17 container with logical databases per app over dokploy-network instead of spawning 8 separate Postgres daemons that waste 1.6 GB of duplicate shared_buffers.
Confirm gate #2 in your BP-01 staging environment.
-
Bind PostgreSQL and Redis strictly to internal Docker DNS names (never publish port 5432 or 6379 to 0.0.0.0) so Docker iptables cannot bypass UFW host rules.
Confirm gate #3 in your BP-01 staging environment.
-
Set hard cgroup memory limits (memory: 512M) and NODE_OPTIONS="--max-old-space-size=384" on runtime containers so a memory leak in one micro-SaaS never starves sibling apps.
Confirm gate #4 in your BP-01 staging environment.

Should multiple indie SaaS apps share one PostgreSQL container in Dokploy? (DokployHub BP-01)
Yes for solo makers and studios up to ~15 apps: one tuned PostgreSQL 17 instance with separate roles and databases per app uses far less RAM and page cache than 10 isolated Postgres containers,
while Dokploy still runs independent per-database hourly pg_dump S3 backups.
Why does Docker publish 5432:5432 expose Postgres even when UFW is enabled? (DokployHub BP-01)
Docker writes DNAT rules directly into the Linux PREROUTING/DOCKER iptables chains before UFW INPUT rules evaluate. Always leave External Port blank in Dokploy database settings so apps connect privately over dokploy-network.
DokployHub Pre-Cutover Verification Principles (BP-01 (dokploy-multi-app-nextjs-postgres-vps))
Between Hostinger and Vultr tiers for Multi App Nextjs Postgres, keeping 30% RAM free above Multi App processes (Nixpacks Builder) RSS enables 60-second DNS rollbacks if Nextjs Postgres host tiers deploys fail.
