One container to rule them all? No. Um, a plastic box* refresher

Containers are the cool toy meaning two things: new technology and hype. At heart, containers are simple: group the minimum set of files needed to run a particular program into a single directory tree, then run it with some kind of isolation mechanism, so that as far as that process is concerned, it's the only thing on the …

Integrity advantage...

The container got corrupted? Full erase and instance again...

Really useful for services. Thinking of local services requesting high availability.

LXD FTW

The only one you really need is LXD. Just ignore all the others, unless some outside influence forces you to muck with them. There is no point to Docker. LXD can do everything Docker can do, plus a whole lot more, with very little added overhead. And you get normal syslogging and all the other normal init management. You don't have to adopt a whole other way of operating inside the container.

LXD is just as useful as KVM or Xen, as long as you are just virtualizing linux inside linux - but with much less overhead.

Great article, thanks Liam. Looking forward to the next one that covers "radical changes in Linux distro design, which we will look at in the next article.".

FreeBSD Jails

FreeBSD has had jails since BSD 4.0. ZFS allows for write-on-copy, thin-cloning, snapshots and a ton of other features. FreeBSD has tools called ezjail and iocage as well as a few others, but unlike GNU/Linux, there is only one underlying technology, making it far more stable and widely compatible.

Oh, and I forgot to mention, it can run GNU as well.
