容器代理的端口报502解决

https://www.656463.com/wenda/ljdsysnginxconnectsb111ljbjj_167 #遇到的问题类似这个,但是我的是node.js环境，搜到的问题是php环境
https://blog.csdn.net/qq_43558459/article/details/110758289 #然后我按这位老铁的方法解决了

ss -lntp | grep 123 #发现端口没有起来
dokcer ps #发现容器没起来
docker start  github #发现报错起不了
因为代码需要容器有wechat依赖
回滚代码到昨天能用的时候
docker start  github #容器起来了

docker logs 容器名 #错误:无法找到模块'微信'

然后再到nginx代理服务器看下日志

tail -n 100 /usr/local/nginx/logs/github.com_error.log
tail -n 100 /usr/local/nginx/logs/github.com_access.log

以及真实服务器，宿主机看下日志

tail -n 100 /data/node_projects/github/server/logs/info.2021-09-24-17.log
