code-server 屏幕截图

介绍

部署 code-server 就可以在浏览器里随时编写代码 😎😎

配置反向代理，通过不同的域名访问到不同端口，这样在可以像在本地一样调试网页了。

比如，在 code-server 中运行将程序运行到 3000 端口，在访问 https://3000-view.oonnnoo.com 访问就可以在线调试程序

PS:如果对应的端口未运行程序，Nginx 就会返回的 502 了。

我是通过 docker-compose 运行的，下面是配置文件，内容仅供参考，需要自行部署。

docker-compose 配置文件

cat docker-compose.yml

version: '3.0'
services:
  ide:
    image: codercom/code-server:3.8.0
    restart: always
    user: coder
    volumes:
      - /srv/ide:/home/coder/project # 项目目录
      - /var/coder/.local/share/code-server:/home/coder/.local/share/code-server
      - ./dotfile/.gitignore:/home/coder/.gitignore # git 全局忽略文件
      - ./dotfile/.gitconfig:/home/coder/.gitconfig # git 全局配置文件
      - ./dotfile/.npmrc:/home/coder/.npmrc # node 配置文件
      - ./dotfile/.bash_profile:/home/coder/.bash_profile 
      - ./dotfile/.ssh:/home/coder/.ssh # ssh 文件为了方便，我单独生成了一个私钥
      - ./dotfile/.pip:/home/coder/.pip # python 配置文件
    expose:
      # 暴露 一个端口范围，用于后续的端口转发
      - "3000-10000"
      # - 8080
    env_file:
      - ./ide.env

  website:
    image: onnno/nginx:latest
    restart: always
    ports:
      - 443:443
      - 80:80
    volumes:
      - /srv/www:/srv/www
      - /etc/nginx/conf.d:/usr/local/nginx/conf.d
      - /var/log/nginx:/usr/local/nginx/logs
      - /etc/letsencrypt:/etc/letsencrypt
    depends_on:
      - ide

用于 code-server 配置文件

cat ide.env

PASSWORD=abcded

PASSWORD 指定是code-server运行后，登录的密码

Nginx 配置文件

ide.conf

遇到的问题及解决方案

在运行 vue 之类的项目的时候，出现以下错误

Error: ENOSPC: System limit for number of file watchers reached, watch '/home/coder/project/ryanlid/sys/public'

解决办法：需要在主机上，不是在docker中执行

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf

sudo sysctl -p
