# docker架設n8n跟nginx proxy
架設n8n時，因為要使用url name來進行連結，但是沒有哪麼多網址時，只能用nginx設定path方式。將proxy導至docker的n8n服務，具體實現的作法如下:

## docker compose
建立docker-compose.yml

version: '3.8'

volumes:
  db_storage:
  n8n_storage:

services:
  postgres:
    image: postgres:16
    restart: always
    environment:
      - POSTGRES_USER
      - POSTGRES_PASSWORD
      - POSTGRES_DB
      - POSTGRES_NON_ROOT_USER
      - POSTGRES_NON_ROOT_PASSWORD
    volumes:
      - db_storage:/var/lib/postgresql/data
      - ./init-data.sh:/docker-entrypoint-initdb.d/init-data.sh
    healthcheck:
      test: ['CMD-SHELL', 'pg_isready -U ${POSTGRES_USER} -d ${POSTGRES_DB}']
      interval: 5s
      timeout: 5s
      retries: 10

  n8n:
    image: docker.n8n.io/n8nio/n8n
    restart: always
    environment:
      - DB_TYPE=postgresdb
      - DB_POSTGRESDB_HOST=postgres
      - DB_POSTGRESDB_PORT=5432
      - DB_POSTGRESDB_DATABASE=${POSTGRES_DB}
      - DB_POSTGRESDB_USER=${POSTGRES_NON_ROOT_USER}
      - DB_POSTGRESDB_PASSWORD=${POSTGRES_NON_ROOT_PASSWORD}
      - N8N_HOST=${DOMAIN_NAME}
      - N8N_PATH=/n8n/   #此為設定path
      - WEBHOOK_URL=http://localhost:5678/n8n/
      - TZ=Asia/Taipei
    ports:
      - "5678:5678" 
    links:
      - postgres
    volumes:
      - ./n8n_storage:/home/node/.n8n
    depends_on:
      postgres:
        condition: service_healthy

建立.env，，此為設定資料庫連線資訊

POSTGRES_USER=isUser
POSTGRES_PASSWORD=isUserPASSWORD
POSTGRES_DB=n8n

POSTGRES_NON_ROOT_USER=isDbUser
POSTGRES_NON_ROOT_PASSWORD=isDbUserPASSWORD

DOMAIN_NAME=localhost

設定好後執行docker

docker-compose up -d

跑起來後檢視docker是否運作正常
因為n8n有設定path，要藉由nginx的proxy子目錄才能進行測試

## nginx設定
nginx設定location path為/n8n/並導向至port 5678

		location /n8n/ {
		# 允许跨域请求			
			proxy_set_header Host $host;
			proxy_set_header X-Real-IP $remote_addr;
			proxy_set_header X-Forwarded-Proto $scheme;
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			proxy_http_version 1.1;
			proxy_set_header Upgrade $http_upgrade;
			proxy_set_header Connection 'upgrade';
			proxy_cache_bypass $http_upgrade;
			proxy_pass http://localhost:5678/;
		}

然後重啓nginx後，即可用url方式連至/n8n/看看運作是否正常。
連結為:https://youUrl/n8n/
