Brooklyn

Apache Brooklyn Client CLI

A command line client for Apache Brooklyn.

Toolchain

The CLI tool is written in Go and should be obtained and built as a standard Go project. You will need the following tools to build it:

  • Go (version 1.6.1 or higher), with full cross-compiler support (see https://golang.org/dl). On Mac, if using Homebrew, use “brew install go --with-cc-all”

Optional:

  • Maven (used by the Brooklyn build process)

  • Maven (see note below on the Brooklyn build process)

Workspace Setup

Go is very particular about the layout of a source tree, and the naming of packages. It is therefore important to get the code from github.com/apache/brooklyn-client and not your own fork. If you want to contribute to the project, the procedure to follow is still to get the code from github.com/apache/brooklyn-client, and then to add your own fork as a remote.

  • Ensure your $GOPATH is set correctly to a suitable location for your Go code, for example, simply $HOME/go.
  • Get the Brooklyn CLI and dependencies.
go get github.com/apache/brooklyn-client/br

Installing Dependencies

The CLI has a small number of dependencies, notably on urfave/cli. To manage the version of dependencies, the CLI code currently uses Glide. The dependencies are installed to the top level ‘vendor’ directory.

go get github.com/Masterminds/glide
cd $GOPATH/src/github.com/apache/brooklyn-client
glide install

Compiling the code with Go for development purposes

Just use the regular Go build commands.

Testing

The code includes a test script in the test directory. This deploys a Tomcat server on a location of your choice and runs a number of tests against it, to verify that the br commands perform as expected. To use this you must edit the file “test_app.yaml” to change the location to your own value, and then invoke the test script like the following, where the username and password need only be supplied if Brooklyn requires them:

sh test.sh  http://your-brooklyn-host:8081 myuser mypassword

Note, the tests are not yet comprehensive, and contributions are welcome.

Building the code as part of the Brooklyn build process

For consistency with the other sub-projects of the overall Brooklyn build, Maven is used to perform the build when brooklyn-client is built as one of the sub-modules of Brooklyn. Most of the work is delegated to the release/build.sh script, which cross-compiles the code for a number of platform-architecture combinations.

Invoke the build script via Maven with one of

  • mvn clean install build for all supported platforms
  • mvn -Dtarget=native clean install build for the current platform
  • mvn -Dtarget=cross -Dos=OS -Darch=ARCH clean install build for platform with operating system OS and architecture ARCH

NOTE This does not build the code into your usual GOPATH. To allow the project to be checked out along with the other Brooklyn submodules and built using Maven, without any special treatment to install it into a separate GOPATH location, the Maven build makes no assumption about the location of the project root directory. Instead, the Maven target directory is used as the GOPATH, and a soft link is created as target/src/github.com/apache/brooklyn-cli to the code in the root directory.

This builds the requested binaries into the “target” directory, each in its own subdirectory with a name that includes the platform/architecture details, e.g. bin/linux.386/br. The build installs a maven artifact to the maven repository, consisting of a zip file containing all the binaries. This artifact can be referenced in a POM as

<groupId>org.apache.brooklyn</groupId>
<artifactId>brooklyn-client-cli</artifactId>
<classifier>bin</classifier>
<type>zip</type>
<version>...</version>
