Deploy and Host n8n on Railway

n8n is a workflow automation tool: visual flows with hundreds of integrations, webhooks, schedules, code steps and AI agent nodes.

This template runs the official image (2.40.7) on Postgres, with n8n's folder on a volume for community nodes and binary data.

About Hosting n8n

A fresh n8n asks whoever opens it first to create the owner account. On a public URL that can be anyone, and most templates leave it open until you get there. This one sets the owner up for you: the deploy form asks for your email, a password is generated into N8N_OWNER_PASSWORD, and a start step creates the owner once n8n is ready, then signs in to confirm it. Open N8N_URL and sign in with that email and password.

My first version of that step fired as soon as /healthz answered, which is while the database migrations are still running, and in my test the owner it created didn't stick: a second setup request from another address then succeeded. The step now waits for /healthz/readiness and retries until signing in works.

Before publishing I tested the final version on a fresh deploy. The start step reported the owner as set up, a setup request from another address was refused with "Instance owner already setup", and the owner signed in with the owner role. A workflow with a webhook trigger, created and activated through the API, ran with status success when I called the webhook. After a restart the workflow was still active and its webhook still answered.

Common Use Cases

Connect your apps with flows triggered by webhooks, schedules or app events
Build AI agent workflows that call models and tools, with credentials stored encrypted

Dependencies for n8n Hosting

Nothing beyond the template: Postgres is included. Integrations need their own credentials, added in n8n.

Implementation Details

N8N_OWNER_EMAIL / N8N_OWNER_PASSWORD   # owner account, set up on first start
N8N_ENCRYPTION_KEY                     # generated; encrypts stored credentials, keep it
WEBHOOK_URL=https:///  # change it when you add a custom domain
DB_TYPE=postgresdb, DB_POSTGRESDB_*    # Postgres over the private network
N8N_RUNNERS_ENABLED=true               # Code nodes run in task runners

The container starts as root only to hand the volume to n8n's node user; the image has no package manager, so the start step drops privileges through Node itself. To upgrade, set N8N_VERSION (an image tag) on the n8n service.

n8n logs that internal task runner mode is deprecated. It still works in 2.40.7; upstream recommends a separate runner process for larger setups.

Idle, n8n used 0.40 GB of RAM and Postgres 0.14 GB.

Why Deploy n8n on Railway?

Webhooks need a public HTTPS address that stays up, and here it's yours from the first minute with nobody else able to claim the owner account. Both services come to about $5 a month in RAM at idle.
