Apache Brooklyn helps to model, deploy, and manage systems.

This root project is a wrapper around subprojects. See individual projects for recent changes.

It supports blueprints in YAML or Java, and deploys them to many clouds and other target environments. It monitors those deployments, maintains a live model, and runs autonomic policies to maintain their health.

Quick Start

This is the uber-repo. To build the entire codebase, get this project and its sub-modules:

git clone https://github.com/apache/brooklyn/
cd brooklyn
git submodule init
git submodule update --remote --merge --recursive

And then, with jdk 1.8+ and maven 3.1+ installed:

mvn clean install

However, this will not build the RPM/DEB packages, as well as the CLI. That's why we would recommand to use the alternative: a docker container to build this project:

docker build -t brooklyn .
docker run -i --rm --name brooklyn -u $(id -u):$(id -g) \
      --mount type=bind,source="${HOME}/.m2/settings.xml",target=/var/maven/.m2/settings.xml,readonly \
      -v /var/run/docker.sock:/var/run/docker.sock \
      -v ${PWD}:/usr/build -w /usr/build \
      brooklyn mvn clean install -Duser.home=/var/maven -Duser.name=$(id -un) -Drpm -Ddeb -Dclient -Ddocker

You can speed this up by using your local .m2 cache:

docker run -i --rm --name brooklyn -u $(id -u):$(id -g) \
      -v /var/run/docker.sock:/var/run/docker.sock \
      -v ${HOME}/.m2:/var/maven/.m2 \
      -v ${PWD}:/usr/build -w /usr/build \
      brooklyn mvn clean install -Duser.home=/var/maven -Duser.name=$(id -un) -Drpm -Ddeb -Dclient -Ddocker

The results are in brooklyn-dist/dist/target/, including a tar and a zip. Or to run straight after the build, do:

pushd brooklyn-dist/karaf/apache-brooklyn/target/assembly/
./bin/start

Non-Git Build

If you are performing a build on code not in source control (e.g. from a ZIP of source code, or after deleting SCM metadata), you will need to manually set two variables that are normally inferred from the environment:

• -DbuildNumber=manual
• -DscmBranch=manual

You can set these properties to any value you wish. When using a checkout from git, the buildNumber is set to the SHA1 commit ID (short form) of the containing project, and the scmBranch is set to the git branch.

Resources

The Developers section of the main website contains more detail on working with the codebase. There is also a more Developer Guide specific to each version, including this branch (1.2.0-SNAPSHOT), latest stable, and older releases.

Useful topics include:

• getting the source code

• setting up Git with forks, submodules (or alternatively avoiding submodules) and other productivity hints

• the maven build and what to do on build errors

• project structure of the codebase and submodules

• the people behind Apache Brooklyn
