n8n-self-hosting: Security & Code Review for AI Agents | OpenAgentSkill

Overview

Deploy a production self-hosted n8n end-to-end to a fresh Linux VM over SSH, using Docker Compose behind a Caddy reverse proxy with automatic HTTPS. Use whenever the user wants to self-host, install, set up, provision, or deploy n8n on their own server/VPS/box (Hetzner, DigitalOcean, AWS EC2, bare metal, etc.) — in either single/regular mode or queue mode with workers — or to update, back up, restore, or harden such an instance. This is for SELF-HOSTED n8n (Docker), not n8n Cloud and not building workflows. The skill makes the agent ask single-vs-queue first, collect the domain/SSH/timezone inputs, generate fresh secrets on the box, and bring the stack up with TLS. Trigger on "deploy n8n", "self-host n8n", "install n8n on my server", "n8n docker compose", "n8n queue mode / workers / scaling", "n8n reverse proxy / SSL", "back up / update my n8n", or "we don't want to give every user the OAuth client secret" / "enable the Sign in with Google button" (credential overwrites).

Deploying self-hosted n8n

This skill takes a fresh Linux VM (Ubuntu/Debian, root or sudo SSH) to a running, HTTPS, production n8n via Docker Compose behind Caddy (automatic Let's Encrypt TLS). It is for self-hosted n8n on Docker — not n8n Cloud, and not for building workflows (that's the rest of this pack).

Two deployment modes. The architectures differ, so pick the mode before doing anything.

You drive this end-to-end over SSH: preflight → install Docker → lay down the project → generate secrets → launch → verify TLS → hand off. The template files live in assets/; the per-mode and security depth live in the reference files named below.

Rule 0 — choose the mode (ask the user)

Do not guess. Ask, then commit to one:

	Single / regular	Queue
Processes	one n8n	main + N workers
Extra services	none (SQLite)	Redis (queue) + Postgres (DB)
Executes workflows	in the main process	on workers, in parallel
Good for	1 user, light/moderate load, simplest ops	high volume, heavy/long executions, horizontal scale
Compose	`assets/docker-compose.single.yml`	`assets/docker-compose.queue.yml`
Deep dive	`SINGLE_MODE.md`	`QUEUE_MODE.md`

If unsure, start single — it's the simplest correct thing and covers most needs. Moving to queue later means swapping the compose file and migrating SQLite→Postgres, so if the user already expects real volume, start queue.

Rule 1 — secret hygiene (non-negotiable)

A misstep here leaks client credentials. Be diligent:

Generate every secret fresh, on the target box. Never copy an encryption key, DB password, or .env from another n8n instance into this one. See SECURITY.md for the openssl commands.
Secrets live only in .env (mode 600), referenced by the compose as ${VAR}. Never inline a secret into docker-compose.yml, the Caddyfile, or anything you commit.
The N8N_ENCRYPTION_KEY is sacred. It encrypts every stored credential. If it's lost or changes, all saved credentials become undecryptable. Set it explicitly, and tell the user to back it up off the box. Don't echo it into long-lived logs or chat history beyond what's needed to hand it over.
Never expose internal services. Only Caddy (80/443) is public. n8n (5678), Postgres (5432), Redis (6379) stay on the private Docker network — the templates already omit their host port mappings. Don't add them.
.env and Caddy's caddy_data volume (the issued certs + ACME account key) are not artifacts to share. If you're working inside a git repo, confirm .env is git-ignored before any commit.

Inputs to collect up front

SSH target — user@host and how you authenticate (key path or the user confirms the agent already has access). Root or a sudo user.
Domain — the full hostname n8n will live at, e.g. n8n.example.com (→ SUBDOMAIN=n8n, DOMAIN_NAME=example.com). The user must control its DNS.
TLS email — for Let's Encrypt (SSL_EMAIL).
Timezone — IANA name for Schedule/Cron nodes (e.g. Europe/Warsaw), else Etc/UTC.
Mode — single or queue (Rule 0). Queue → confirm the box has enough RAM (rough floor ~4 GB; each worker wants ~1–2 GB).
Optional modules — some features (currently Agents) are backend modules that stay off unless listed in N8N_ENABLED_MODULES. Ask only if the user brings one up; if they do, read the modules section of QUEUE_MODE.md before enabling it, because in queue mode it has to reach the workers as well.

The deploy flow

Work through these in order. SINGLE_MODE.md / QUEUE_MODE.md give the mode-specific command detail; SECURITY.md covers secret generation and hardening; DAY2.md covers update/backup/restore.

1. Preflight (the cheapest failure is the one you catch here)

SSH in; confirm the OS is Debian/Ubuntu-like (. /etc/os-release).
DNS must already point at the box. Compare the box's public IP (curl -s ifconfig.me) with dig +short <fqdn> (run it from the box AND ideally your laptop). If they don't match, stop — Caddy's ACME challenge will fail. Have the user create the A record, wait for it to propagate, then continue.
Ports 80 and 443 must be reachable from the internet. Check the host firewall AND any cloud security group / network firewall (Hetzner Cloud, AWS SG, etc.) — these are outside the box and a common silent blocker.

2. Install Docker (if absent)

Check docker --version and docker compose version. If missing, install Docker Engine + the Compose plugin (Docker's official get.docker.com script on Ubuntu/Debian is fine). Re-check docker compose version before proceeding.

3. Lay down the project

Pick DATA_FOLDER — an absolute path, e.g. /opt/n8n. The DATA_FOLDER value in .env must equal this exact directory (the compose mounts ${DATA_FOLDER}/caddy_config/Caddyfile, and init-data.sh is mounted via a relative ./ path), so always run docker compose from here. Create it, plus caddy_config/ and local_files/ inside.
Get the template files onto the box. They live in this skill's assets/ on your machine, not on the server — transfer each one. Either scp them up, or (no local copy needed) write each file's contents over SSH, e.g. ssh <target> 'cat > <DATA_FOLDER>/docker-compose.yml' < assets/docker-compose.single.yml. Land them with these exact names:
- the chosen compose → <DATA_FOLDER>/docker-compose.yml (rename it to exactly this)
- Caddyfile → <DATA_FOLDER>/caddy_config/Caddyfile
- queue only: init-data.sh → <DATA_FOLDER>/init-data.sh, then chmod +x it
- the matching .env.*.example → <DATA_FOLDER>/.env

4. Fill `.env` + generate secrets

Set DATA_FOLDER, DOMAIN_NAME, SUBDOMAIN, SSL_EMAIL, GENERIC_TIMEZONE.
Generate each secret on the box with openssl (SECURITY.md has the commands) and write it into .env, replacing the matching REPLACE_WITH_… placeholder: N8N_ENCRYPTION_KEY; queue also POSTGRES_PASSWORD + POSTGRES_NON_ROOT_PASSWORD.
Before launching, confirm none are left unset: grep REPLACE_WITH_ .env must return nothing — a leftover placeholder becomes the literal password and Postgres/n8n fail to connect.
chmod 600 .env. Record the encryption key so the user can back it up off-box.

5. Firewall

ufw: allow OpenSSH + 80 + 443, then enable. Do not open 5678/5432/6379.

6. Launch

cd <DATA_FOLDER> && docker compose up -d.
Queue mode brings up Redis + Postgres + main + workers (workers via replicas). To add capacity: docker compose up -d --scale n8n-worker=N.

7. Verify (don't declare success without this)

docker compose ps — every service Up/healthy (queue: postgres & redis healthy first).
n8n itself up (internal): docker compose exec n8n wget -qO- http://localhost:5678/healthz → {"status":"ok"}. This separates "n8n is running" from "TLS isn't ready yet."
Cert issued: docker compose logs caddy | grep -i 'certificate obtained'. First-boot ACME can take a minute or two; until it finishes, a public https:// request fails TLS — that means the cert is still pending, not that n8n is down.
Public reachability (with retry): curl -fsS --retry 5 --retry-delay 10 https://<fqdn>/healthz → {"status":"ok"}. (/healthz only proves the process is reachable; /healthz/readiness additionally confirms the DB is connected and migrated — use it when debugging a boot loop.)
Queue mode — main and workers must agree. Diff their environments: diff <(docker compose exec -T n8n env | sort) <(docker compose exec -T --index 1 n8n-worker env | sort). Only the public-URL/proxy vars should differ. Anything else means a behavioural setting reached the main but not the workers — and workers are what execute workflows, so it fails at runtime in one node rather than at boot. QUEUE_MODE.md explains the rule.
Open https://<fqdn> → the owner setup screen. Whoever completes that signup form first claims the instance — an exposed un-owned instance is a race, so create the owner account immediately, before sharing the URL. Enable 2FA. (Automated deploys can pre-provision the owner via env vars instead — see the owner row in SECURITY.md.)

8. Hand off

Give the user: the URL, where the project lives, the encryption key to store safely, and the Day-2 basics (update / backup / restore) from DAY2.md.

What NOT to do

Don't skip the DNS/ports preflight. A wrong A record or a closed cloud firewall is the #1 reason Caddy can't get a cert and n8n looks "broken."
Don't publish 5678/5432/6379 to the host. Caddy reaches n8n over the private network.
Don't reuse another instance's encryption key or .env. Fresh secrets per box.
Don't run queue mode on SQLite. Queue requires Postgres (the template already wires it).
Don't put secrets in docker-compose.yml or the Caddyfile. .env only.
Don't add a behavioural env var to the main only (queue mode). Modules, DB, queue, binary-data and encryption settings belong in the shared x-n8n-env anchor so workers get them too; only the public-URL/proxy vars are main-only. See QUEUE_MODE.md.
Don't use :latest blindly. Pin N8N_IMAGE_TAG; update deliberately (DAY2.md).

# Deploying self-hosted n8n

This skill takes a **fresh Linux VM** (Ubuntu/Debian, root or sudo SSH) to a **running,
HTTPS, production n8n** via Docker Compose behind **Caddy** (automatic Let's Encrypt TLS).
It is for **self-hosted n8n on Docker** — not n8n Cloud, and not for building workflows
(that's the rest of this pack).

Two deployment modes. The architectures differ, so **pick the mode before doing anything**.

You drive this end-to-end over SSH: preflight → install Docker → lay down the project →
generate secrets → launch → verify TLS → hand off. The template files live in `assets/`;
the per-mode and security depth live in the reference files named below.

## Rule 0 — choose the mode (ask the user)

Do not guess. Ask, then commit to one:

| | **Single / regular** | **Queue** |
|---|---|---|
| Processes | one n8n | main + N workers |
| Extra services | none (SQLite) | Redis (queue) + Postgres (DB) |
| Executes workflows | in the main process | on workers, in parallel |
| Good for | 1 user, light/moderate load, simplest ops | high volume, heavy/long executions, horizontal scale |
| Compose | `assets/docker-compose.single.yml` | `assets/docker-compose.queue.yml` |
| Deep dive | **`SINGLE_MODE.md`** | **`QUEUE_MODE.md`** |

If unsure, start **single** — it's the simplest correct thing and covers most needs. Moving
to queue later means swapping the compose file and migrating SQLite→Postgres, so if the user
already expects real volume, start **queue**.

## Rule 1 — secret hygiene (non-negotiable)

A misstep here leaks client credentials. Be diligent:

1. **Generate every secret fresh, on the target box.** Never copy an encryption key, DB
   password, or `.env` from another n8n instance into this one. See `SECURITY.md` for the
   `openssl` commands.
2. **Secrets live only in `.env`** (mode 600), referenced by the compose as `${VAR}`. Never
   inline a secret into `docker-compose.yml`, the Caddyfile, or anything you commit.
3. **The `N8N_ENCRYPTION_KEY` is sacred.** It encrypts every stored credential. If it's lost
   or changes, all saved credentials become undecryptable. Set it explicitly, and tell the
   user to back it up **off the box**. Don't echo it into long-lived logs or chat history
   beyond what's needed to hand it over.
4. **Never expose internal services.** Only Caddy (80/443) is public. n8n (5678), Postgres
   (5432), Redis (6379) stay on the private Docker network — the templates already omit their

Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Deploy a production self-hosted n8n end-to-end to a fresh Linux VM over SSH, using Docker Compose behind a Caddy reverse proxy with automatic HTTPS. Use whenever the user wants to self-host, install, set up, provision, or deploy n8n on their own server/VPS/box (Hetzner, DigitalOcean, AWS EC2, bare metal, etc.) — in either single/regular mode or queue mode with workers — or to update, back up, restore, or harden such an instance. This is for SELF-HOSTED n8n (Docker), not n8n Cloud and not building workflows. The skill makes the agent ask single-vs-queue first, collect the domain/SSH/timezone inputs, generate fresh secrets on the box, and bring the stack up with TLS. Trigger on \"deploy n8n\", \"self-host n8n\", \"install n8n on my server\", \"n8n docker compose\", \"n8n queue mode / workers / scaling\", \"n8n reverse proxy / SSL\", \"back up / update my n8n\", or \"we don't want to give every user the OAuth client secret\" / \"enable the Sign in with Google button\" (credential overwrites).
