# Scripts

## get-coreos

Run the `get-coreos` script to quickly download CoreOS kernel and initrd images, verify them, and move them into `assets`.

    ./scripts/get-coreos                 # beta, 899.6.0
    ./scripts/get-coreos alpha 942.0.0

This will create:

    assets/
    └── coreos
        └── 899.6.0
            ├── coreos_production_pxe.vmlinuz
            └── coreos_production_pxe_image.cpio.gz
        └── 942.0.0
            ├── coreos_production_pxe.vmlinuz
            └── coreos_production_pxe_image.cpio.gz
