Warden: CloudFoundry's Linux container library

Has anyone used OpenVZ along with either ProxMox or the free openvz webpanel, as I have?

With all the noise about LXC based solutions I wonder if some wouldn't be just as happy with OpenVZ.

openvz doesn't seem to be known outside of hosting/hosters community, otherwise - it's quite a mature container engine

The ancestor of Docker at dotCloud ran on openvz. We moved to lxc in 2010 when it became usable.

I think of them as mostly interchangeable except for the shared hosting use case where openvz has a head start (more time for more eyeballs to audit and fix it).

Now the whole "openvz vs. lxc" distinction is pretty moot - linux has namespaces and cgroups. Everything else is a matter of choice of userland libraries and cli tools.

Warden is similar to Docker, every container gets a read-only and a read-write filesystem assigned and Warden provides an API for creating and destroying containers.

jambay provides more info on Warden in this other HN thread: https://news.ycombinator.com/item?id=6488258

thanks, much more accurate than my explanation.

Ironically, Warden is also the name of the tool used in PC-BSD to manage FreeBSD Jails.

Probably obvious, but there's another ruby project named Warden as well (handles user authentication): https://github.com/hassox/warden

This project looks pretty cool, though.

Yeah, I thought it was funny mostly cause FreeBSD Jails and Docker have really a lot of things in common
