The problem here is you are familiar with Docker but not LXC which has suffered serious misinformation from the Docker ecosystem.
A little bit of research will show it's far simpler to use and manage than Docker [1], and because it offers a standard OS environment with support for standard networking, daemons, logging, no enforced use of layers or ephemeral storage it doesn't need an app to hang around and manage its networking and other subsystems.
It offers seamless migration of workloads from VMs, is compatible with the ecosystem of apps and orchestration systems without the need for any special daemon handling, network or storage management that comes from a custom environment, thus simplifying container use and management.
