How to check if engine is built with seccomp

docker

(Krystalcode) #1

Hello,

I’m trying to debug a seccomp-related warning where a container complains that the kernel is buggy and I should upgrade. I am running on a Fedora 23 host with kernel version “4.5.7”, “libseccomp” package is installed, the command “cat /boot/config-uname -r | grep CONFIG_SECCOMP=” returns “CONFIG_SECCOMP=y” as it should based on https://github.com/docker/docker/blob/master/docs/security/seccomp.md. I would like to verify that docker as well has been built with seccomp, so that I am certain that the host is ok and there may be something wrong with the program that is complaining.

How can I verify that Docker is built with seccomp and everything is ok on that side?

Docker version 1.10.3, installed from the official Fedora 23 repositories.
