解决CentOS7下运行docker容器时出现的报错Error resolving sysca

Linux就该这么学

最近在研究docker!在虚拟机centos7中运行docker经常会有:

 

[jm@localhost docker]$ docker run -it lin/centos6 /bin/bash

2016/11/08 19:38:53 Error resolving syscall name execveat: could not resolve name to syscall - ignoring syscall.

2016/11/08 19:38:53 Error resolving syscall name getrandom: could not resolve name to syscall - ignoring syscall.

[root@c3f9a779dc59 /]# 



提示。但是容器的功能都能正常使用。

【解决】

只需要安装或更新软件包libseccomp至2.2版本以上即可消除此报错提示!

[jm@localhost docker]$ sudo yum -y install libseccomp
