我在重新构建启动器时突然遇到了以下错误。这些 Discourse 实例已经运行多年，一直没有问题，而且 YAML 文件自上次成功更新 Discourse 以来也未曾修改。非常感谢您的任何帮助。
Launcher is up-to-date
Stopping old container
+ /usr/bin/docker stop -t 10 app
app
cd /pups && git pull && /pups/bin/pups --stdin
/usr/bin/docker: invalid reference format: repository name must be lowercase.
See '/usr/bin/docker run --help'.
cat: cids/app_bootstrap.cid: No such file or directory
"docker rm" requires at least 1 argument.
See 'docker rm --help'.
Usage: docker rm [OPTIONS] CONTAINER [CONTAINER...]
Remove one or more containers
rm: cannot remove 'cids/app_bootstrap.cid': No such file or directory
** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one.
./discourse-doctor may help diagnose the problem.
此外，我尝试查看 /pups 目录，但系统提示该目录不存在？
我可以通过简单地重新启动容器，让 Discourse 实例恢复正常运行。
