quay.io/tinkerbell/actions/slurp:latest

This action will stream the contents of a block device to a remote server allowing a user to easily make a copy of a remote server. This newly created disk image can be replicated to easily provision other servers.

Slurp will read directly from a block device, it can compress this stream and will use the HTTP protocol to transmit the raw data to a listening server. The remote server needs to be able to handle multipart data (due to the size) and reform this to a disk image locally.

The below example will stream a raw ubuntu installed on /dev/sda and uplopad it to a remote server.

actions:
- name: "slurp_ubuntu"
  image: quay.io/tinkerbell/actions/slurp:latest
  timeout: 90
  environment:
    DEST_URL: http://192.168.1.2:3000/image
    SOURCE_DISK: /dev/sda
    IMG_NAME: ubuntu_wordpress
    COMPRESSED: false

Note the DEST_URL, the slurp action has a server that can be used with this action. It can be started with go run server/main.go -port 3000, which will create a web server that has a handler on the url /image to manage images that are uploaded too it.
