Dotnet Core SDK Cloud Native Buildpack

The Dotnet Core SDK CNB provides a version of the Dotnet Core SDK and a version of the Dotnet Core Driver or the dotnet binary. It also sets the Dotnet Core SDK on the$DOTNET_ROOT so that it is available to subsequent buildpacks during their build phase and sets the Dotnet Core Driver on the $PATH so that is available to subsequent buildpacks and in the final running container.

Integration

The Dotnet Core SDK CNB provides the dotnet-sdk as a dependency. Downstream buildpacks, like Dotnet Core Build can require the dotnet-sdk dependency by generating a Build Plan TOML file that looks like the following:

[[requires]]

  # The name of the Dotnet Core SDK dependency is "dotnet-sdk". This value is considered
  # part of the public API for the buildpack and will not change without a plan
  # for deprecation.
  name = "dotnet-sdk"

  # The version of the Dotnet Core SDK dependency is not required. In the case it
  # is not specified, the buildpack will provide the default 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 "3.*", "3.1.*", or even
  # "3.1.100".
  version = "3.1.100"

  # The Dotnet Core SDK buildpack supports some non-required metadata options.
  [requires.metadata]

    # Setting the build flag to true will ensure that the Dotnet Core SDK
    # depdendency is available in the $DOTNET_ROOT for subsequent buildpacks during
    # their build phase and ensures that the Dotnet Core Driver dependency is available
    # in the $PATH for subsequent buildpacks. If you are writing a buildpack that needs
    # to use the dotnet sdk & driver during its build process, this flag should be set
    # to true.
    build = 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

dotnet-sdk:
  # this allows you to specify a version constaint for the dotnet-sdk dependency
  # any valid semver constaints (e.g. 2.* and 2.1.*) are also acceptable
  version: "2.1.804"
