问题
根据CentOS安装docker指南,启动hello-world时报错,提示信息中提到了OCI runtime
,根本原因是 runc did not terminate successfully
[root@localhost composetest]# sudo docker run hello-world
docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: unable to retrieve OCI runtime error (open /run/containerd/io.containerd.runtime.v2.task/moby/4a7cc9e9d0d66c8db7f9cd68ffa2631c54d3e3dab4c408fd2af564b1cd496536/log.json: no such file or directory): runc did not terminate successfully: exit status 127: unknown.
ERRO[0000] error waiting for container:
解决
参考【错误解决】docker找不到runc:failed to create shim: OCI runtime create failed: unable to retrieve OCI runtime,这个问题跟runc
有关,查看docker版本的确没有runc信息

查看docker状态,提示没有runc

最终查到可能是libseccomp
版本过低引起的,看一下当前版本
[root@localhost composetest]# rpm -qa | grep libseccomp
libseccomp-2.3.3-3.el8.x86_64
升级
yum update libseccomp
升级后再查看docker 版本已经有runc
了。文章来源:https://www.toymoban.com/news/detail-632165.html

总结
解决过程中遇到了OCI
、runc
等名词,根据Docker,containerd,CRI-O和runc之间的区别得知,OCI
是open container initiative
,是一套关于镜像和容器的规范,它也提供了实现就是runc,runc
是用来创建和运行容器的。文章来源地址https://www.toymoban.com/news/detail-632165.html
