Dify on a VPS: Prepare the AI Application Platform for Production

A self-hosted Dify deployment is more than web/API: workers, database, Redis, sandbox and storage cooperate. “Containers are up” is not sufficient evidence of production health.

Production note

Do not interpret Dify’s baseline memory as “Dify plus local model.” Local inference adds CPU/GPU VRAM and system RAM requirements; size platform and inference separately.

Current Dify self-host documentation gives a Docker VM baseline of at least 2 vCPU and 8 GiB memory. If model inference runs on the same host through Ollama/vLLM, add that workload on top.

Quick answer

Current Dify self-host documentation gives a Docker VM baseline of at least 2 vCPU and 8 GiB memory. If model inference runs on the same host through Ollama/vLLM, add that workload on top.

01

Technical scope at a glance

Deploy Dify on a VPS with Docker Compose using a production-oriented design for resources, workers, PostgreSQL/Redis, storage, domain, TLS, backups and upgrades.

2 vCPUDocumented baseline

Minimum CPU starting point for the Dify Docker VM.

8 GiBDocumented baseline RAM

Baseline for platform components, excluding local model inference.

ComposeSelf-host deployment

The official quick start uses Docker Compose.

StatefulData components

Database, cache and file/object storage lifecycles need separate protection.

1. Map Dify components before installation

Web UI, API, workers, scheduler, database, Redis and sandbox have different failure modes. Separate state and network requirements.

2. Validate the Docker VM baseline

Swap pressure and disk exhaustion can surface as worker timeouts or secondary failures. Record the baseline before deployment.

3. Treat Compose configuration as a versioned vendor snapshot

Instead of blindly pulling upstream Compose changes into production, review diffs against your `.env` and overrides.

Command
docker compose config > /tmp/dify-effective.yml
Command
docker compose pull
Command
docker compose ps
Command
docker compose logs --tail 120 api worker
05

4. Treat `.env` as sensitive as backups

Database, Redis, model-provider and application secrets can coexist in one environment file. Control permissions, rotation and off-host escrow.

Command
stat -c "%a %U:%G %n" .env
Command
grep -E "^[A-Z0-9_]+=" .env | cut -d= -f1 | sort
06

5. Test streaming and websocket behavior through the reverse proxy

AI responses can be long-lived; streaming connections need different timeout behavior from short HTTP requests.

Observe whether upstream work continues after client abort.
Set proxy read timeout around model latency.
Test large upload/document ingestion limits.
07

6. Split platform backup into three data classes

Database, uploaded files/object storage and configuration/secrets may need different backup methods. One tar archive is not automatically a consistent backup.

7. Rehearse schema and worker compatibility in staging

Long mixed-version windows between API and workers can expose queue or schema incompatibilities. Match rollout behavior to release notes.

EKA SUNUCU · TECHNICAL

Size Dify platform resources separately from model inference

On Eka Sunucu VPS/GPU infrastructure, plan the Dify control plane and Ollama/vLLM inference on one or separate servers according to workload.

FAQ

Frequently asked questions

Dify VPS

Is 8 GB RAM enough for Dify?

It is a documented Docker VM baseline. More is needed as datasets, worker concurrency and local inference grow.

Does Dify run the model itself?

Dify is an application/agent platform that connects to model providers/APIs. Local inference can be supplied by Ollama/vLLM separately.

Can Dify run production on one VPS?

For small workloads yes, but platform, database and inference may share one failure domain. Design backups and resource isolation accordingly.

What should be backed up before an upgrade?

At minimum keep recoverable copies of PostgreSQL data, uploaded/storage content and critical environment/secrets configuration.
