In the context of Wikitech container usually means a Linux Container as in LXC.
- en-wp:LXC (Linux Containers)
"Userspace (FUSE) filesystem offering two main things:
- Overlay files for cpuinfo, meminfo, stat and uptime.
- A cgroupfs compatible tree allowing unprivileged writes.
It's designed to workaround the shortcomings of procfs, sysfs and cgroupfs by exporting files which match what a system container user would expect."
LXD is a container manager.
"LXD is the new LXC experience. It offers a completely fresh and intuitive user experience with a single command line tool to manage your containers. Containers can be managed over the network in a transparent way through a REST API. It also works with large scale deployments by integrating with cloud platforms like OpenNebula and OpenStack."
