n8n Template on Vertra Cloud: Workflows with Python and JavaScript

Visual workflow automation. The template runs n8n 2.44.7 with the Code node in JavaScript and Python in the same container, an optional worker in queue mode and community nodes.

Step-by-step guide: n8n from zero to your first workflow

Choose the mode, create the owner, webhooks, Python and JavaScript, SMTP, credentials, backups and rollback.

What it creates

Mode	Creates	Memory
Managed Postgres (default)	The n8n app and a managed Postgres.	2 GB
Built-in SQLite	The n8n app only.	1 GB
Scale with workers	The n8n app, one worker, Postgres and Redis.	3.5 GB

It is an image template: it needs a plan with Docker images and one free image slot. See Plans and limits.

What the wizard asks

Question	What it does
How will n8n run?	The mode above.
Parallel executions on the worker	Only with workers. Default 5.
Schedule time zone	America/Sao_Paulo, UTC, America/New_York or Europe/Lisbon.
Modules allowed in the Code node	Safe (default) or All.
Send n8n emails?	Optional SMTP for invitations and password reset.

What you get

The app address, and the next step: open it and create the owner account right away. Secrets (the encryption key and the runners token) are generated for you.

Variables

Variable	What it does
`N8N_ENCRYPTION_KEY`	Encrypts credentials; keep a copy. Never change it on a running app.
`N8N_WEBHOOK_URL`, `N8N_EDITOR_BASE_URL`, `N8N_HOST`	The app’s public address.
`VERTRA_CODE_MODULES`	`safe` or `all`: the modules the Code node may import.
`GENERIC_TIMEZONE`, `TZ`	Schedule time zone.
`EXECUTIONS_DATA_MAX_AGE`, `EXECUTIONS_DATA_PRUNE_MAX_COUNT`	History retention: 168 hours and 5,000 executions.
`N8N_WORKER_CONCURRENCY`	Parallel executions on the worker (workers mode).
`N8N_SMTP_*`, `N8N_EMAIL_MODE`	Email for invitations and password reset.

Resources and limits

Port 5678; first boot 25 to 60 seconds. Editor memory use about 300 to 540 MiB, worker 330 to 560 MiB.
Data in /app/.n8n; community nodes in /app/.n8n/nodes.
One worker at most; zero-downtime deploy is off; rollback returns the data too.
Execution history is deleted after 7 days or 5,000 executions.
