Source Removal Cloud Native Buildpack

This buildpack is meant to be used at the end of the buildpack order definition and will delete files in the application directory if either $BP_INCLUDE_FILES or $BP_EXCLUDE_FILES.

Buildpack Configuration

This buildpack will always pass detection will not delete any files that are in your application directory.There are two ways to control what files are deleted by this buildpack.

$BP_INCLUDE_FILES

If you want a specific subset of files to remain in your buildpacks application directory flag them to be included using the environment variable $BP_INCLUDE_FILES which is a list of globs.

$BP_INCLUDE_FILES=file/glob/*:file/some-file

$BP_EXCLUDE_FILES

If you want a specific subset of files to be in your buildpacks application directory flag them to be included using the environment variable $BP_EXCLUDE_FILES which is a list of globs.

$BP_EXCLUDE_FILES=file/glob/*:file/some-file

Overlapping logic

If both are set then the include logic will run followed by the exclude logic.

Usage

To package this buildpack for consumption:

$ ./scripts/package.sh

This builds the buildpack's Go source using GOOS=linux by default. You can supply another value as the first argument to package.sh.

Library Usage

The logic to implement this buildpack is isolated to a package called logic, which can be used if you want to incorporate the same logic in your buildpack or library. This package does reference packit or libcnb/libpak so it can be used from either style buildpack.

import "github.com/initializ-buildpacks/source-removal/logic"

Then you can run logic.Exclude("foo/*") or logic.Include("foo/*").
