@ -4,14 +4,10 @@ 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 `./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.
The plugin also needs to know where the kernel and `initrd` images are
located. The `--vm-lib` command line argument to the plugin specifies
the directory. Inside the VM library directory every kernel/initrd configuration should be stored in a sub-directory. The sub-directory name is used in the instance configuration.
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
@ -24,7 +20,7 @@ make
To play round with the plugin, simply follow the [infrakit tutorial](https://github.com/docker/infrakit/blob/master/docs/tutorial.md) and replace the file instance plugin with:
```
./build/infrakit-instance-hyperkit --vm-lib ./vmlib
./build/infrakit-instance-hyperkit
```
where `./vmlib` contains a sub-directory named `default` with a `vmlinuz64` and `initrd.img` image.
