I would like to boot a Docker container using PXE network booting.
I've read that Docker containers don't really boot and I've also read about the fundamentals of network booting. I understand that Docker containers don't have a BIOS and that they can't be configured to perform a PXE network-boot in the usual way (via the BIOS).
That said, I'm hoping that there's some simple way of simulating network booting with Docker containers. Maybe there's some sort of BIOS emulator that facilitates this? Or maybe there's a PXE software client that can be run in a container?
My motivation here is not necessarily to use PXE as a tool to help deploy Docker containers, but rather to use Docker to help experiment with and prototype systems that use PXE - single-host and multi-host systems - before deploying them to physical machines.
I found the following StackOverflow post which asks essentially the same question:
Unfortunately there were no solutions there - probably because no such solution exists.
If there's an alternative container technology (i.e. operating-system-level virtualization) for Linux that supports this use case then I would accept that as well. Again, I realize that this is a long shot.
