On: Containers vs. Zones vs. Jails vs. VMs

Its probably a good time to stop using containers to mean LXC considering the new OCI runc specs containers on Solaris using Zones and Windows using Hyper-V:

I don't think anyone in the container dev community thinks that containers means LXC only. Even back in 2013, docker's front end api was designed to support other runtimes such as VMs and chroot. Perhaps this is a marketing story gone awry?

Afaik even the docker noob tutorial already points out that it is not just LXC only.

Docker hasn't support LXC as a backend for at least a year.

You mean they replaced it? May also what I've read. Unsure.

[cyphar → erikb]

They've been using libcontainer and then moved to runC (which is effectively a standard-compliant wrapper around libcontainer) since before 1.0. LXC was only used in the early history of Docker, and it was pretty bad to be quite honest (it's better now but there's no chance Docker will switch back).

It's probably a good idea time to stop thinking that anyone cares what Solaris calls anything.
