copy

Caution

Only compiler-based builds can use this module as it is built-in to the BlueBuild CLI tool.

The copy module is a short-hand method of adding a COPY instruction into the image. This can be used to copy files from images, other stages, or even from the build context.

Usage

The copy module’s properties are a 1-1 match with the COPY instruction containing src, dest, and from (optional). The example below will COPY the file /usr/bin/yq from docker.io/mikefarah/yq into /usr/bin/.

modules:
- type: copy
  from: docker.io/mikefarah/yq
  src: /usr/bin/yq
  dest: /usr/bin/

Creating an instruction like:

COPY --linked --from=docker.io/mikefarah/yq /usr/bin/yq /usr/bin/

Omitting from: will allow copying from the build context:

modules:
- type: copy
  src: file/to/copy.conf
  dest: /usr/etc/app/

Creating an instruction like:

COPY --linked file/to/copy.conf /usr/etc/app/

Example configuration

type: copy
from: docker.io/mikefarah/yq
src: /usr/bin/yq
dest: /usr/bin/

Configuration options

from: (optional string)

Equivalent to the —from property in a COPY statement, use to specify an image to copy from. By default, the COPY source is the build environment’s file tree.

src: (required string)

Path to source file or directory.

dest: (required string)

Path to destination file or directory.
