ctr

[root@master ~]# ctr --help
NAME:
   ctr - containerd CLI

USAGE:
   ctr [global options] command [command options] [arguments...]

VERSION:
   v1.6.19

DESCRIPTION:

ctr is an unsupported debug and administrative client for interacting with the containerd daemon. Because it is unsupported, the commands,options, and operations are not guaranteed to be backward compatible or stable from release to release of the containerd project.

ctr是一个不受支持的调试和管理客户端，用于与containerd守护进程交互。由于不支持它，因此无法保证命令、选项和操作在containerd项目的各个版本之间向后兼容或稳定。
