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 1.15 or higher).
• Maven (optional, used by the Brooklyn build process)

Workspace Setup

Go is very particular about the layout of a source tree and the source repository, as it relies on this in the naming of packages.

If you're familiar with Go and just want to develop the br tool itself you may simply work in your usual manner, using go get github.com/apache/brooklyn-client/cli/br and adding your own fork as a remote.

br is built just like any other Go project. Dependencies are managed through Go modules.

Compiling the code with Go for development purposes

Just use the regular Go build commands:

go build -o target/br ./br

The binary is now ready to use in target/br.

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, cross-compiling 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

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. (When using this build process, the build script also writes the Go module cache into this directory.) 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

<project>
    <groupId>org.apache.brooklyn</groupId>
    <artifactId>brooklyn-client-cli</artifactId>
    <classifier>bin</classifier>
    <type>zip</type>
    <version>1.2.0-SNAPSHOT</version>  <!-- BROOKLYN_VERSION -->
</project>

Most of the work is delegated to the release/build.sh script; it is not normally necessary to use this, but if you need to know more, try release/build.sh -h for more information.
