Well, I had a hunch it was for this reason. I usually get grumpy when an arguably superior solution is presented as an 'alternative' to something that's just more popular because it's easier that way for people to grok what it's all about. But on the other hand, I've never been good at marketing, so who am I to complain. :)
- shykes 13y agoDocker and Jails are not directly comparable, the same way Docker and raw lxc are not directly comparable. Docker operates at a higher level of abstraction, and uses lxc as a low-level sandboxing tool. It could (and soon will) offer a choice of multiple sandboxing backends beyond lxc, for example simple chroot (for older linux kernels), openvz, libvirt, etc. There are also people experimenting with using Jails and Solaris zones as a backend to docker. From what I'm reading, this project cbsd sounds like a more direct competitor of docker + a future jails backend.
- nzp 13y agoYeah, don't get me wrong, I think Docker is great. I remember when I first heard about it thinking "Finally, something approaching jails functionality in Linux." Of course, I know it's a different level of abstraction and all that. My comments were more directed at the underlying Linux infrastructure Docker uses. Granted, I may well be wrong, it's been a long time since I was seriously in Linux land (i.e. not just a mindless day-to-day user), I'm not current with hard technicalities so it's totally possible that I'm being unjust to LXC. I'm happy to hear about plans for different backends, the jails one would be awesome if it comes to fruition.
