|===========================================================
LXC vs LXD vs Docker::
LXC is a userspace interface for the Linux kernel containment
features. Through a powerful API and simple tools, it lets Linux users easily
create and manage system containers. +
LXD is building on top of LXC to provide a new, better user experience. Under
the hood, LXD uses LXC through liblxc and its Go binding to create and manage
the containers. It's basically an alternative to LXC's tools and distribution
template system with the added features that come from being controllable over
the network. +
LXC, as well as the former OpenVZ, aims at *system virtualization*, ie
allows you to run a complete OS inside a container, where you log in as ssh,
add users, run apache, etc...
Docker aims at running a *single* application running in a contained
environment. Hence you're managing a docker instance from the host with the
docker toolkit.
NOTE: Proxmox VE aims at system virtualization, and thus uses LXC as the basis
of its own container offer. You can however perfectly install and use docker
inside a VM, and thus getting the benefit of software containerization
with the very strong isolation that VMs provide.
