Docker 容器启动报错的解决方法

环境：

• Docker : 20.10.7
• 系统：centos 7.9.2009
• Docker安装方式:rpm包安装

错误信息

Docker服务没有任何问题，但是当容器启动时报如下错误：

docker: Error response from daemon: OCI runtime create failed: unable to retrieve OCI runtime error (open /run/containerd/io.containerd.runtime.v2.task/moby/40b48d6f9ea6c0bbcbaa9413adb1914b41e4750465125742203b5d2cb72d3c06/log.json: no such file or directory): runc did not terminate successfully: unknown.
ERRO[0000] error waiting for container: context canceled

仔细看上边的报错，有一句runc did not terminate successfully: unknown.,猜测是runc导致的
运行runc:

$ runc
runc: error while loading shared libraries: libseccomp.so.2: cannot open shared object
file: No such file or directory

问题解决

通过上边执行runc命令发现少libseccomp.so.2动态库。应该是系统没安装libseccomp库。
安装libseccomp-2.3.1-4.el7.x86_64.rpm (直接搜索可以找到下载地址)

$ rpm -ivh libseccomp-2.3.1-4.el7.x86_64.rpm

再次启动容器成功！
