Anyone know of virtualisation like this?
This is for educational purposes only...
Does anyone know of very, very simple Linux container virtualisation software? The only feature I need it to support is to be migrateable between different servers. So, for example:
- User deploys a server with Provider X using OS A.
- They run a script that gives them a single virtualised environment to work in
- They decide they want to move to Provider Y using OS B
- They re-run the script on the new server and run 1 command to copy the environment over.
If this doesn't exist, can anyone point me in the right direction about building something like this? LXC/VZ are way too complex for this.
This is to solve the problem of having to set up application dependencies again and again for each new server.

No clue, sorry.
Edit: Docker, maybe?
UML maybe, but it is still too complex - you need to setup networking, etc. when you move it to a new place.
Maybe just run your application inside a chroot jail on top of any VPS or server?
Couldn't find anything useful with normal searches but I found some really useful projects on Github. I think I'll be learning from & adapting this one:

Docker and chroot are the only things that spring to mind, but I'm not sure if chroot would support the migration aspect.
