Unlike LXC containers Docker containers do not behave like lightweight VMs and cannot be treated as such. Docker containers are restricted to a single application by design. The Docker base OS template is pared down to a single app environment and does not have a proper init or support things like services, daemons, syslog, cron or running multiple applications. (from http://www.flockport.com/lxc-vs-docker/ - this can be explained and worded better?). In addition Docker containers are ephemeral as your only option. Unlike LCX which is an option, "lxc-start-ephemeral".
