起因

一直在用alist-strm,这几天编辑了一下Docker容器就无法正常启动了报错可以参考一下

/usr/lib/python3/dist-packages/supervisor/options.py:474: UserWarning: Supervisord is running as root and it is searching for its configuration file in default locations (including its current working directory); you probably want to specify a "-c" argument specifying an absolute path to a configuration file for improved security.

重新拉取镜像还是有问题，而且日志少的可怜，根本看不出是是什么阻止了程序启动

解决

进入容器看看能不能找到描述更细的日志

docker exec -it <容器ID或名称> /bin/bash  # 默认使用Bash,还需要替换一下自己的容器名称

进入logs文件夹，找到了flask.out.log 发现是解压文件错误（file is not a zip），更懵了，因为不知道为什么会解压文件，只能翻源码。这是用python写的，源码就是app.py.

发现这个应用每次启动就会检查更新，但是作者维护的更新地址有问题了，所以才报错，所以我们这里禁用更新就行,在源码最下面把的check_and....这一行注解掉就可以

可能会用到的命令

#安装文本编辑器
apt-get update 
apt-get install vim 

#进入容器终端

docker exec -it <容器ID> /bin/bash

#进入指定目录

docker exec -it <容器ID> bash -c "cd /path && bash"

#宿主机复制容器文件

docker cp <容器ID>:/path/file ./<宿主机存放目录>
