解決CentOS7下運行docker容器時出現的報錯Error resolving sysca

最近在研究docker！在虛擬機器centos7中運行docker經常會有：

[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.

2016/11/08 19:38:53 Error resolving syscall name set_tls: 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。

【解決】

只需要安裝或更新軟體包libseccomp至2.2版本以上即可消除此報錯提示！

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