See RHEL and Debian sections: https://thehftguy.com/2017/02/23/docker-in-production-an-upd... The filesystem drivers are buggy as fuck. You would experience kernel panics on Debian Jessie (overlayFS), or containers + docker daemon hanging on CentOS 6 (devicemapper). The fix in both cases is a reboot. You might not notice it if you barely used docker, but it can be very outstanding at scale. I've been consulting briefly at a major web company that was deploying their web services to 5-20 nodes, daily. On every service deployment there would be up to 3 nodes dying. |
