docker exec：rpc错误：code = 2 desc = oci运行时错误：exec失败

时间：2016-12-13 14:03:26

标签： linux docker ubuntu-16.04

每次我尝试做的事情：

$ docker exec

我收到错误消息：

 rpc error: code = 2 desc = oci runtime error: exec failed:   container_linux.go:247: starting container process caused "process_linux.go:83: executing setns process caused \"exit status 16\""

第1节（按预期工作）：

$ docker images

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

$ docker run --rm --name alpine -it alpine sh
/ # pwd

第二节：

$ docker ps -a

$ docker exec -it alpine sh

$ docker exec -it 7bd39b37aee2 sh 
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "process_linux.go:83: executing setns process caused \"exit status 16\""

/ var / log / syslog显示了一些警告，但我无法理解找不到匹配答案的根本原因。

感谢任何提示。

您应该尝试使用标准的Docker CE版本

https://docs.docker.com/install/linux/docker-ce/ubuntu/

您的问题应在以后解决。

From the linked issue is this comment which appears to be the root cause:

I think I found the root reason. It's nothing to do with Docker.

Actually docker exec always fail because of Symantec AutoProtect running on my system. It loads a custom kernel module that add some file operation hooks, which affects the result of setns.

$ lsmod | grep symev
symev_custom_dkms_x86_64 72166 2 symap_custom_dkms_x86_64

The workaround is to disable Symantec AutoProtect and reboot.

sudo update-rc.d autoprotect disable
