docker-swift-dev-buildbot

Docker Buildbot for the Apple Swift language

Runs the Swift buildbot_linux build preset in Ubuntu 16.04/14.04 and Fedora 23 containers. Use for local development unit testing or automated builds.

Source code is accessed on the host machine via a Docker Volume at /src. The build log build-${TIMESTAMP}.log and an install package (on success) swift-${TIMESTAMP}-ubuntu${VERSION}.tar.gz are written to the Volume /output after each build.

Pre-built containers available on Docker Hub at: https://hub.docker.com/r/eosrei/swift-dev-buildbot/

Dockerfiles and Tags

• Ubuntu 16.04 LTS: latest,16.04 (Dockerfile)
• Ubuntu 14.04 LTS: 14.04 (Dockerfile)
• Fedora 23: fedora23 (Dockerfile)

Setup

This process requires a copy of the Swift project codebase to share with the containers. The source can be a location on the host machine or as a linked Volume in another container. The examples assume local development.

Example Swift project cloning, further details at the Swift Github project page:

mkdir swift
cd swift
git clone https://github.com/apple/swift.git swift
./swift/utils/update-checkout --clone-with-ssh

Get the container images and the builds:

docker run --name swift-16 -v $PWD:/src -v $PWD:/output eosrei/swift-dev-buildbot:16.04
docker run --name swift-14 -v $PWD:/src -v $PWD:/output eosrei/swift-dev-buildbot:14.04
docker run --name swift-f23 -v $PWD:/src -v $PWD:/output eosrei/swift-dev-buildbot:fedora23

Note: OS X and Windows with Docker Machine must use volume locations within /Users (OS X) or C:\Users (Windows). Details:

• http://docs.docker.com/engine/userguide/dockervolumes/#mount-a-host-directory-as-a-data-volume

Usage

Subsequent builds will reuse build artifacts and run quickly; ~1.5hrs vs ~20 minutes in my experience.

Run the Ubuntu 16.04 LTS build:

docker start -i -a swift-16

Run the Ubuntu 14.04 LTS build:

docker start -i -a swift-14

Run the Fedora 23 build:

docker start -i -a swift-f23
