1、创建腾讯云密钥
SecretId SecretId
登录 – 腾讯云
腾讯云为数百万的企业和开发者提供安全、稳定的云服务器、云主机、CDN、对象存储、域名注册、云存储、云数据库等云服务，帮助用户解决游戏、视频、移动、微信、互联网+等行业的架构难题，是全球领先的云计算服务商。
2、创建旧版IDE Studio 容器
注意创建免费版1c2g 8g存储 （用来跑自己的轻量服务，中转访问墙外站点都可以；当然他也有送每个月1w分钟的机时，你也可以通过api控制某个时间段启动关闭容器，当然我只用免费版,不过有个缺点就是只能源码部署，不支持docker）
设置永不休眠
进入容器中设置永不休眠
然后我发现这个免费容器虽然设置永不休眠，但是每次启动会持续运行1440分钟。
偶尔可能会中断几秒或者1分钟，没衔接上保活
Cloud studio
编辑程序自启动脚本
再次重启容器的话由于不支持docker, 想要控制容器内部程序启动的方式就是配置
.vscode/preview.yml 结合空间密钥 使用browserless api 无头浏览器访问你的ide空间地址， 触发相关程序启动
3、官方接口控制容器保活

获取 spaceKey 相当于空间id
记住刚刚免费容器的spaceKey
创建free空间对应的空间密钥
空间密钥通过腾讯云密钥创建，空间密钥需要上面的spaceKey, 创建空间密钥的时候将过期时间设置长一点
保活脚本大致参考

5、其他说明worker 自调用需要设置下global_fetch_strictly_publicworker 需要启用兼容性标志才能自己调用自己 global_fetch_strictly_public然后我发现同一个实名用户创建的多个账户，每个账户都可以创建免费ide空间实例，我目前跑了5个 free space, 稳定运行几个月了大致是这样子，笔记丑陋凑活看看，等佬友完善补充下
