Method: Pkg::Util::File.fetch

Defined in:
lib/packaging/util/file.rb

.fetch ⇒ Object

The fetch method pulls down two files from the build-data repo that contain additional data specific to Puppet Labs release infrastructure intended to augment/override any defaults specified in the source project repo, e.g. in ext/build_defaults.yaml

It uses curl to download the files, and places them in a temporary directory, e.g. /tmp/somedirectory/project,team/Pkg::Config.builder_data_file

Retrieve build-data configurations to override/extend local build_defaults
