## Source File
|
||
- [[raw/Agent/n8n docker install & update.md]]
|
||
|
||
## Summary
|
||
- 核心主题：n8n 工作流自动化工具的 Docker 部署与网络代理配置
|
||
- 问题域：Docker 容器化部署、网络代理配置、宿主机代理访问
|
||
- 方法/机制：Docker Compose 编排、Dockerfile 自定义镜像、SOCKS5 代理配置
|
||
- 结论/价值：实现 n8n 容器内科学上网，支持工作流自动化执行
|
||
|
||
## Key Claims
|
||
- n8n 可通过 Docker Compose 快速部署，配置数据卷持久化
|
||
- 容器内网络流量可通过 SOCKS5 代理访问外网
|
||
- 需将宿主机代理监听地址改为 `0.0.0.0` 使容器可访问
|
||
- Docker 网桥 IP（Gateway）可通过 `docker network inspect` 获取
|
||
|
||
## Key Quotes
|
||
> "注意：`172.21.0.1` 需替换为以下命令输出的网桥 IP（Gateway）"
|
||
|
||
> "V2Ray/Tuic 配置中 **本地监听地址改为 `0.0.0.0`**，端口假设为 `10808`"
|
||
|
||
## Key Concepts
|
||
- [[Docker]]：容器化平台
|
||
- [[Docker-Compose]]：Docker 编排工具，定义多容器应用
|
||
- [[Dockerfile]]：容器镜像构建文件
|
||
- [[SOCKS5代理]]：支持 TCP/UDP 的网络代理协议
|
||
- [[Docker-网桥]]：Docker 虚拟网桥，容器与宿主机通信的桥梁
|
||
|
||
## Key Entities
|
||
- [[n8n]]：开源工作流自动化工具
|
||
|
||
## Connections
|
||
- [[n8n]] ← runs_in ← [[Docker]]
|
||
- [[Docker]] ← uses ← [[Docker-Compose]]
|
||
- [[Docker]] ← built_from ← [[Dockerfile]]
|
||
- [[n8n]] ← accesses_network_via ← [[SOCKS5代理]]

|
||
## Docker Compose 配置
|
||
|
||
```yaml
|
||
version: '3.8'
|
||
services:
|
||
n8n:
|
||
build: .
|
||
image: docker.n8n.io/n8nio/n8n
|
||
container_name: n8n
|
||
ports:
|
||
- "5678:5678"
|
||
volumes:
|
||
- n8n_data:/home/node/.n8n
|
||
environment:
|
||
- N8N_PROTOCOL=https
|
||
- N8N_HOST=n8n.ishenwei.online
|
||
- WEBHOOK_URL=https://n8n.ishenwei.online/
|
||
- N8N_TRUST_PROXY=true
|
||
- N8N_SECURE_COOKIE=true
|
||
- N8N_PROXY_HOPS=1
|
||
- ALL_PROXY=socks5://172.21.0.1:10808
|
||
restart: unless-stopped
|
||
|
||
volumes:
|
||
n8n_data:
|
||
|
||
networks:
|
||
n8n_default:
|
||
external: true
|
||
```
|
||
|
||
## Dockerfile 配置
|
||
|
||
```dockerfile
|
||
FROM n8nio/n8n:latest
|
||
USER root
|
||
RUN apk update && apk add --no-cache curl wget
|
||
USER node
|
||
```
|
||
|
||
## 更新步骤
|
||
|
||
```bash
|
||
cd /path/to/your/compose/file/directory
|
||
docker compose pull
|
||
docker compose down
|
||
docker compose up -d
|
||
```
|
||
|
||
## 容器内测试代理
|
||
|
||
```bash
|
||
docker exec -it n8n /bin/sh
|
||
curl --socks5 172.18.0.1:10808 https://ifconfig.me
|
||
