This is the Bluemix buildpack for Swift applications, powered by the Swift Package Manager (SPM). Though this buildpack was developed mainly for Bluemix, it can be used on any Cloud Foundry environment. This buildpack requires access to the Internet for downloading and installing several system level dependencies.
Please note that this buildpack is not yet installed on Bluemix; our team is working on getting it installed soon. Having said that, you can still use this buildpack to deploy your Swift applications to Bluemix as described in the Usage section below.
Also, check out the Kitura-Starter-Bluemix for a fully working example of a Kitura-based server application that can be deployed to Bluemix (or any Cloud Foundry environment).
Example usage:
$ cf push -b https://github.com/IBM-Swift/swift-buildpack.git

$The buildpack will detect your app as Swift if it has a Package.swift file in the root.
Using the Procfile, you can specify the name of executable process (e.g. Server) to run for your web server. Any binaries built from your Swift source using SPM will be placed in your $PATH. You can also specify any runtime parameters for your process in the Procfile.
web: Server --bind 0.0.0.0:$PORT
Instead of specifying IP address and port values in the Procfile as runtime parameters to your web server process, you can instead use the Swift-cfenv package to obtain such values at runtime. The Swift-cfenv package provides structures and methods to parse Cloud Foundry-provided environment variables, such as the port number, IP address, and URL of the application. It also provides default values when running the application locally. For details on how to leverage this library in your Swift application, see the README file. When using Swift-cfenv in your app, your Procfile will be very simple; it will more than likely look like this:
web: <executable_name>
The latest version of Swift supported by this buildpack is swift-DEVELOPMENT-SNAPSHOT-2016-05-03-a.
You can also customize the version of Swift used with a .swift-version file in your repository:
$ cat .swift-version
swift-DEVELOPMENT-SNAPSHOT-2016-05-03-aFor a list of the Swift supported versions, check out the manifest.yml file. Since there are frequent Swift language changes, it's advised that you pin your application to a specific Swift version. Once you have tested and migrated your code to a newer version of Swift, you can then update the .swift-version file with the appropriate Swift version.
This buildpack installs the following system libraries:
- libcurl3
- libblocksruntime-dev
- libkqueue0
Once Foundation (Linux) provides complete networking functionality and libdispatch is bundled up with the Swift binaries, there won't be a need for installing these system libraries.
As yet, the Swift binaries (for Linux) do not include the libdispatch library. It is expected that this library will be fully integrated with the Swift binaries at some point later this year. As a stopgap solution, this buildpack includes the libdispatch binaries for the following Swift versions:
- swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a
- swift-DEVELOPMENT-SNAPSHOT-2016-04-25-a
- swift-DEVELOPMENT-SNAPSHOT-2016-05-03-a
If the buildpack preparation or compilation steps are failing, you can enable some debugging using the following command:
cf set-env <app_name> BP_DEBUG trueTo deactivate:
cf unset-env <app_name> BP_DEBUGTo install this buildpack:
wget https://github.com/IBM-Swift/swift-buildpack/releases/download/v1.1.0/swift_buildpack-cached-v1.1.0.zip
cf create-buildpack swift_buildpack swift_buildpack-cached-v1.1.0.zip <position>
And to update it:
wget https://github.com/IBM-Swift/swift-buildpack/releases/download/v1.1.0/swift_buildpack-cached-v1.1.0.zip
cf update-buildpack swift_buildpack -p swift_buildpack-cached-v1.1.0.zip
For more details on installing buildpacks, see Adding buildpacks to Cloud Foundry.
The buildpack zip file provided in each release is built using manifest-cached.yml file:
BUNDLE_GEMFILE=cf.Gemfile bundle install
BUNDLE_GEMFILE=cf.Gemfile bundle exec buildpack-packager --cached --use-custom-manifest manifest-cached.ymlFor details on packaging buildpacks, see buildpack-packager.
