See: issue #3934

Specific resolution from Dave Sanderson:

Quote:

I've had the same issue and was able to work around it by setting the following with sysctl
kernel.grsecurity.chroot_deny_chmod=0
kernel.grsecurity.chroot_deny_mknod=0
It would probably be better to write a policy for the binary.

Specific fix instructions:
edit /etc/sysctl.conf so that it has the lines

kernel.grsecurity.chroot_deny_chmod=0
kernel.grsecurity.chroot_deny_mknod=0

This will make the settings stick past reboot... and for immediate relief, execute sysctl --system to reload the settings.

Thanks! It's works:

#!/bin/sh
apk add docker
sysctl -w kernel.grsecurity.chroot_deny_chmod=0
sysctl -w kernel.grsecurity.chroot_deny_mknod=0
service docker start
sleep 5
docker --version
docker pull hello-world
docker pull alpine
docker images
