### Linux Containers On Windows (LCOW)
|
||||
|
||||
The [LCOW](./lcow.yml) file contains the blueprint for building a
|
||||
minimal Linux kernel and initrd for Linux Containers on
|
||||
Windows. Invoke it with `moby build lcow.yml` and you get a
|
||||
`lcow-kernel` and `lcow-initrd.img`. Rename `lcow-kernel` to
|
||||
`bootx64.efi` and `lcow-initrd.img` to `initrd.img` and then
|
||||
follow
|
||||
[these instructions](https://github.com/moby/moby/issues/33850). The
|
||||
process for creating the image is
|
||||
documented [here](https://github.com/Microsoft/opengcs).
|
||||
The LCOW blueprint has moved to [its own
|
||||
repository](https://github.com/linuxkit/lcow).
