NAME¶

rkt-prepare - Prepare to run image(s) in a pod in rkt

SYNOPSIS¶

rkt prepare [OPTIONS]

DESCRIPTION¶

Prepares the pod and returns its UUID for a subsequent call to run-prepared.

Prepare is useful to get the UUID of the pod before running or when preparing takes a long time.

IMAGE should be a string referencing an image; either a hash, local file on disk, or URL. They will be checked in that order and the first match will be used.

An "--" may be used to inhibit rkt prepare's parsing of subsequent arguments, which will instead be appended to the preceding image app's exec arguments. End the image arguments with a lone "---" to resume argument parsing.
