ICU Cloud Native Buildpack

The ICU CNB provides International Components for Unicode libraries.

Integration

The ICU CNB provides icu as a dependency. Downstream buildpacks, like Dotnet Core Conf CNB can require the icu dependency by generating a Build Plan TOML file that looks like the following:

[[requires]]

  # The name of the ICU dependency is "icu". This value is considered
  # part of the public API for the buildpack and will not change without a plan
  # for deprecation.
  name = "icu"

  # The version of the ICU dependency is not required. In the case it
  # is not specified, the buildpack will provide the newest version, which can
  # be seen in the buildpack.toml file.
  # If you wish to request a specific version, the buildpack supports
  # specifying a semver constraint in the form of "66.*", "66.1.*", or even
  # "66.1.0".
  version = "66.1.0"

  # The ICU CNB supports some non-required metadata options.
  [requires.metadata]

    # Setting the build flag to true will ensure that the ICU
    # depdendency is available on the $PATH for subsequent buildpacks during
    # their build phase. If you are writing a buildpack that needs to run ICU
    # during its build process, this flag should be set to true.
    build = true

    # Setting the launch flag to true will ensure that the ICU dependency is
    # available on the $PATH for the running application. If you are writing an
    # application that needs to run ICU at runtime, this flag should be set to
    # true.
    launch = true

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.

buildpack.yml Configurations

The icu buildpack does not support configurations using buildpack.yml.
