Hyperkit/Moby Infrakit plugin
This is a Hyper/Kit Moby instance plugin for infrakit. The instance plugin is capable to start/manage several hyperkit instances with with different configurations and Moby configurations.
The plugin keeps state in a local directory (default
.infrakit/hyperkit-vms) where each instance keeps some state in a
sub-directory. The VM state directory can be specified at the kernel
command line using the --vm-dir option.
Building
make
(you need a working docker installation, such as Docker for Mac)
Quickstart
This is roughly based on the infrakit tutorial. You need to have the infrakit binaries in your path (or adjust the invocation of the commands below). To get the binaries, it's best to compile from source (checkout https://github.com/docker/infrakit.git, then make or make build-in-container). The add the ./build directory to your path.
Start the default group plugin:
infrakit-group-default
and the vanilla flavour plugin:
infrakit-flavor-vanilla
Then start the hyperkit plugin:
./build/infrakit-instance-hyperkit
Next, you can commit a new configuration. There is a sample infrakit config file in hyperkit.json. It assumes that you have a default moby build in the top-level directory. The Moby property needs to be of the form <dir>/<prefix> and assumes that the kernel and initrd images are called <prefix>-bzImage and <prefix>-initrd.img respectively (this is the convention used by the moby tool).
infrakit group commit hyperkit.json
This will create a single hyperkit instance with its state stored in
~/.infrakit/hyperkit-vms. There is a tty file which you can
connect to with screen to access the VM.
If you kill the hyperkit process a new instance will be restarted. If
you change the VM parameter in JSON file and commit the new config, a
new VM will be created. f you change the Size parameter, multiple
VMs will get started.
