Getting Started with LXC

The manpages on https://linuxcontainers.org/ are also pretty good.

What distro are you using? What do you recommend?

At home I'm running CentOS 7 as a host. For my website it's Ubuntu 15.10. Ubuntu has been developing more on the platform it seems. Even just small things like lxc-ls -f aren't available on CentOS. It's lsx-ls --active and it gives you no container info at all.

Alex Sage

And what one do you recommend? ;=)

It seems to be favored on Ubuntu. But I want a expert option

Ha I'm far from an expert :-P. I think I'd still use CentOS for the host. When LXD is fully developed, that might change however.

The whole LXD vs LXC things confuses me...

It's not vs. One is a new interface to the other. It's always LXC containers.

Should I worry about this?

Either lxc-attach or lxc-console. Console gives you Norma console type access. Attach just drops you into root in the root folder.

You'll need lxc+-attach to set up sudo and everything
