Deploy n8n with Nginx using Portainer

隨着 OmniFocus4 推出開始打算 review 一下之前在 IFTTT上建立的 Applet。一段時間沒有用，現在我們這些窮L免費用戶只能用兩 Applet。既然而既然如此，於是打算一不做二不休自己搭建n8n。

由於 n8n 的官方 docker compose 是使用 Traefik。大家看，非常複雜哩。

version: "3.7"

services:
  traefik:
    image: "traefik"
    restart: always
    command:
      - "--api=true"
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.web.http.redirections.entryPoint.to=websecure"
      - "--entrypoints.web.http.redirections.entrypoint.scheme=https"
      - "--entrypoints.websecure.address=:443"
      - "--certificatesresolvers.mytlschallenge.acme.tlschallenge=true"
      - "--certificatesresolvers.mytlschallenge.acme.email=${SSL_EMAIL}"
      - "--certificatesresolvers.mytlschallenge.acme.storage=/letsencrypt/acme.json"
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - traefik_data:/letsencrypt
      - /var/run/docker.sock:/var/run/docker.sock:ro

  n8n:
    image: docker.n8n.io/n8nio/n8n
    restart: always
    ports:
      - "127.0.0.1:5678:5678"
    labels:
      - traefik.enable=true
      - traefik.http.routers.n8n.rule=Host(`${SUBDOMAIN}.${DOMAIN_NAME}`)
      - traefik.http.routers.n8n.tls=true
      - traefik.http.routers.n8n.entrypoints=web,websecure
      - traefik.http.routers.n8n.tls.certresolver=mytlschallenge
      - traefik.http.middlewares.n8n.headers.SSLRedirect=true
      - traefik.http.middlewares.n8n.headers.STSSeconds=315360000
      - traefik.http.middlewares.n8n.headers.browserXSSFilter=true
      - traefik.http.middlewares.n8n.headers.contentTypeNosniff=true
      - traefik.http.middlewares.n8n.headers.forceSTSHeader=true
      - traefik.http.middlewares.n8n.headers.SSLHost=${DOMAIN_NAME}
      - traefik.http.middlewares.n8n.headers.STSIncludeSubdomains=true
      - traefik.http.middlewares.n8n.headers.STSPreload=true
      - traefik.http.routers.n8n.middlewares=n8n@docker
    environment:
      - N8N_HOST=${SUBDOMAIN}.${DOMAIN_NAME}
      - N8N_PORT=5678
      - N8N_PROTOCOL=https
      - NODE_ENV=production
      - WEBHOOK_URL=https://${SUBDOMAIN}.${DOMAIN_NAME}/
      - GENERIC_TIMEZONE=${GENERIC_TIMEZONE}
    volumes:
      - n8n_data:/home/node/.n8n

volumes:
  traefik_data:
    external: true
  n8n_data:
    external: true

建立 volume
#

而小白的我只會最簡單的 Nginx Proxy manager，所以只好利用 Portainer 部署 n8n。

打開Portrainer，首先在 volume 中建立一個名叫 n8n-data 的 volume

加入 container
#

Name - n8n
Image - n8nio/n8n:latest
Always pull the image - Enabled
Manual network port publishing - Host: 5678 / Container: 5678

然後在下面 Advanced container settings 中 start with volumes 選項

Map additional volume.

container - /home/node/.n8n
volume - 我們剛剛建立的volume n8n-data

設定環境參數
#

在 Env 選擇 Advanced Mode 貼上以下參數。

TZ=Asia/Hong_Kong 
GENERIC_TIMEZONE=Asia/Hong_Kong
WEBHOOK_URL=http://my-ip-address:5678
EXECUTIONS_DATA_SAVE_ON_SUCCESS=none
EXECUTIONS_DATA_PRUNE=true
EXECUTIONS_DATA_MAX_AGE=24
DB_SQLITE_VACUUM_ON_STARTUP=true
