Databases

How database services work in dFlow Applications: create, deploy, connect with internal or public credentials, and use reference variables from your apps.

Databases overview

Step-by-step: add a managed database to an environment, deploy it, verify credentials, and connect an app using reference variables.

Create a database service

Run PostgreSQL (Postgres) on dFlow: deploy, read internal credentials, wire apps with POSTGRES reference variables, and use Expose when needed.

PostgreSQL

Run MySQL on dFlow: deploy, use internal credentials or MYSQL reference variables, and optionally Expose for external clients.

MySQL

Run MariaDB on dFlow: MySQL-compatible SQL, MARIADB reference variables, internal credentials, and optional Expose.

MariaDB

Run MongoDB on dFlow: document database, MONGO reference variables, and multi-port behavior when you Expose.

MongoDB

Run Redis on dFlow for cache and fast data: REDIS reference variables, connection URL, and optional Expose.

Redis

Run ClickHouse on dFlow for analytics: CLICKHOUSE reference variables, connection fields, and multi-port Expose.

ClickHouse

Create internal database backups on the server, restore from a dump, delete backups, and understand current limits and roadmap items.

Backups and restore

Internal vs public credentials, how reference variables resolve, security practices, and when to use Expose.

Database credentials and connections

Connect apps to third-party databases via Variables and network paths; compare to first-party database Services on dFlow compute.

External database notes

Fix common database deploy, connection, Expose, backup, and reference-variable issues in dFlow Applications.

Introduction

Welcome to dFlow: what the platform is, what makes it different, and where to go next, including dFlow Cloud and self-hosting.

Welcome to dFlow

Beyond the welcome page: comparisons, trade-offs, and when another tool might be a better fit.

Why choose dFlow

Capabilities across applications, environments, services, compute, data, and platform operations.

What you can do with dFlow

Decide between dFlow Cloud and self-hosted dFlow before you open task-by-task guides.

Choose your path

Canonical terms used across dFlow documentation and the product UI.

Glossary

Getting Started

Decide dFlow Cloud vs self-hosted control plane, then follow the matching quick start and first-deploy path.

Shortest path on dFlow Cloud: account, Worker Node, Application, first Service deployment.

Quick start for dFlow Cloud

Install the control plane, then complete first-time Worker Node onboarding (SSH, Dokku, domain).

Quick start for Self-Hosted dFlow

Sign up for dFlow Cloud, verify email, and reach your dashboard at app.dflow.sh.

Create your account and workspace

What to expect after your first login: workspace, navigation, and where Applications and Worker Nodes live.

First login and dashboard tour

Configure a Service from Git, a Docker image, or a database template, then deploy.

Deploy your first app

Add a database Service inside an Application, deploy it, and know where credentials and connections live.

Create your first database

Pick a template from the marketplace or library, instantiate Services, and deploy with guided defaults.

Use your first template

After your first deploy: domains, team access, integrations, databases depth, and operations.

Next steps after setup

Core Concepts

Top-down map of organisations, applications, environments, services, and deployments.

How dFlow is structured

How the control plane, worker nodes, networking, builds, and monitoring fit together.

Platform architecture

Organisation as tenant boundary: members, billing, and how “tenant” maps to the product UI.

Organisations and tenants

Application entity and how it groups environments.

Applications

Environment isolation and compute attachment.

Environments

Services

Worker Nodes execute Services for Environments; how they relate to the control plane and managed compute.

Worker Nodes

What a Deployment represents, how it relates to Services and Environments, and where operations apply.

Deployments

How templates accelerate setup: marketplace, library, and relationship to Applications and Services.

Templates

Conceptual model for backups: scope by Service type, environments, and where task guides live.

Backups

Map legacy Projects to Applications, Environments, and Services; links for mixed legacy/new rollout states.

Legacy Projects vs Applications

dFlow Cloud

Why use dFlow Cloud, where to sign in, browser requirements, and how it relates to your Worker Nodes.

dFlow Cloud overview

After sign-up: what your cloud workspace is and the checklist to reach a first deployment.

Create your cloud workspace

Self-hosted Worker Nodes vs managed compute on dFlow Cloud; attach compute to Environments and separate from self-hosting the control plane.

Choose compute / managed infrastructure

When billing appears on dFlow Cloud, what to prepare, and links to subscription and usage docs.

Payment setup

Authorize GitHub, GitLab, or other providers on app.dflow.sh so Services can build from repositories.

Connect your Git provider

Plan, fair use, builds, and support expectations for dFlow Cloud vs self-hosted control planes.

Cloud limits and expectations

Org access, compute, Git, secrets, operations, and legacy Project migration habits on dFlow Cloud.

Cloud best practices

Self-Hosting dFlow

Why self-host the dFlow control plane, core Compose components, and links to install guides.

Self-hosting overview

CPU, RAM, storage, and software requirements for self-hosting the dFlow control plane.

System requirements

dFlow Cloud vs self-hosting the control plane, and how to pick an install path.

Installation options

Run the dFlow control plane from the official Compose stack: prerequisites, env files, and first boot.

Install with Docker / Docker Compose

Environment variables and secrets for the self-hosted control plane (Compose, URLs, integrations).

Environment configuration

Private networking for the self-hosted control plane, including Tailscale and access patterns.

Tailscale and networking

TLS certificates and hostnames for the self-hosted dashboard and Traefik (control plane).
