Build Status

HyperContainer - Hypervisor-agnostic Docker Runtime

This repo contains two parts: the daemon of HyperContainer hyperd and the CLIhyperctl.

What is HyperContainer?

HyperContainer is a hypervisor-agnostic technology that allows you to run Docker images on plain hypervisor.

Why HyperContainer?


HyperContainer combines the best from both worlds: VM and Container.

- Container VM HyperContainer
Isolation Weak, shared kernel Strong, HW-enforced Strong, HW-enforced
Portable Yes, but kernel dependent sometimes No, hypervisor dependent Yes, hypervisor agnostic and portable image
Boot Fast, sub-second Slow, tens of seconds Fast, sub-second
Performance Great OK Good, minimal resource footprint and overhead
Immutable Yes No, configuration management required Yes, only kernel+image
Image Size Small, MBs Big, GBs Small, MBs
Compatibility No, need new tools Great, everything just works Good, it is still a "Machine", much less changes
Mature Not yet Production ready, SDN, SDS, LiveMigration, etc. Yes, just plug-&-play
ROI Rebuild everything with container - Reuse your virtual infrastructure

*BYOK = bring your own kernel

Requirements

  • QEMU 2.0 or later (QEMU 2.6 or later for ARM64 Architecture)
  • Xen 4.5 and VT enabled host (for Xen support)

Installation

Ensure you are running Linux (kernel 3.8 or later) and have QEMU (version 2.0 or later) installed. Then download the binaries and install them (hyper-container and hyperstart) directly.

For the detail of installation, please refer to the documents.

For information on using the command line, just type hyperctl. You may use hyperctl <command> --help for detailed information on any specific command.

Build From Source

Clone hyperd in GoPath

> mkdir -p ${GOPATH}/src/github.com/hyperhq
> cd ${GOPATH}/src/github.com/hyperhq
> git clone https://github.com/hyperhq/hyperd.git hyperd

And make sure you have go (>= 1.7) , device-mapper-devel, and autotools, go into the hyperd dir

> ./autogen.sh
> ./configure
> make

Then you can find the binaries hyperd daemon and hyperctl cmdline tool in current directory. Before running those commands, a config file needs to be placed at /etc/hyper/config directory, and you can find a sample under ${TOP}/package/dist/etc/hyper/config. Kernel and Initrd are required for starting the hyperd daemon, you can find those files from HyperStart project.
