CC100 Docker Daemon Issues after Reboot

I had a problem like this on a couple of CC100s and fixed it by doing a quick and dirty SLEEP workaround in the docker startup script. I think docker ends up in a limbo mode if the boot isn’t clean and everything else on the CC100 tries to start up at the same time.

I modified /etc/rc.d/S99_docker and added sleep 180 before it starts the daemon.

function do_docker_start()
{
    echo "configuring network..."
    firewall_hook_activate
    echo -n "starting docker daemon..."
    sleep 180
    start-stop-daemon -S --background --quiet --oknodo --pidfile $DOCKER_PIDFILE --exec /usr/bin/env PATH="/"$DOCKER_IPTABLES_PATH":$PATH"  /usr/bin/dockerd --             #manipulate iptables-binary path!
}

After this I’ve never experienced the same problem again. The 180 seconds is just a random number I selected to be sure that everything else is done starting up.
