How to extract build artifacts

[detjensrobert]

Configuration

Items in the provide: list can be either a single string or a object with explicit keys.

from: indicates the challenge container image where the file should be fetched from, based on the names in pods:. If omitted the default value is the repo challenge directory.

include: is the list of file paths to read from the source. String is equivalent to one-element array.

as: either renames the file or creates a zip of the files before uploading.

• If as is given with only one source file, the source is renamed to the value.
• If as is given with multiple files included, the files are zipped into an archive with the filename as the value.
• If omitted, the basename of the file(s) are used and no renaming or archiving occurs (each file is listed individually).

examples

provide:
    # reads thing.jpg from chal directory and shown as thing.jpg
  - thing.jpg

    # copied from foo pod image and zipped together as things.zip
  - from: foo
    as: things.zip
    include: 
      - /lib/foo.so
      - /bin/pwnme

    # copied from foo pod image and shown as thing2
  - from: foo
    as: thing2
    include:
      - /bin/otherthing

Implementation

along the lines of:

• docker create $IMAGE --name tempimage
• docker cp ..files
• docker rm tempimage
