错误信息如下:

ctr: failed to create shim task: OCI runtime create failed: unable to retrieve OCI runtime error (open /run/containerd/io.containerd.runtime.v2.task/i4t/nginx/log.json: no such file or directory): runc did not terminate successfully: exit status 127: unknown

[root@web01 ~]# ctr -n i4t c ls
CONTAINER IMAGE RUNTIME
nginx docker.io/library/nginx:alpine io.containerd.runc.v2
[root@web01 ~]# ctr -n i4t task start -d nginx

原因是 runc 异常，需要重新安装依赖
解决办法:
这个是说缺少依赖包libseccomp，需要注意的是centos7中 yum 下载的版本是 2.3 的，版本不满足我们最新 containerd 的需求，需要下载 2.4 以上的

NAME:
runc - Open Container Initiative runtime
runc is a command line client for running applications packaged according to
the Open Container Initiative (OCI) format and is a compliant implementation of the
Open Container Initiative specification.
runc integrates well with existing process supervisors to provide a production
container runtime environment for applications. It can be used with your
existing process monitoring tools and the container will be spawned as a
direct child of the process supervisor.
Containers are configured using bundles. A bundle for a container is a directory
that includes a specification file named "config.json" and a root filesystem.
The root filesystem contains the contents of the container.
To start a new instance of a container:
