Docker命令进阶

在容器中以某用户进入

这个用户只有在容器中才有，比如NextCloud容器里，就是以www-data在运行

root@dev-server:/data/cloud.amicap.cn/data# docker exec -u www-data -it nextcloud /bin/bash
www-data@b3df309e1882:~/html$ php occ files:scan --all 
Starting scan for user 1 out of 2 (admin)
Starting scan for user 2 out of 2 (david)

容器反复重启，无法进入容器怎么办？
