A command line client for Apache Brooklyn.
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 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.
Just use the regular Go build commands:
go build -o target/br ./br
The binary is now ready to use in target/br
.
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.
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 platformsmvn -Dtarget=native clean install
build for the current platformmvn -Dtarget=cross -Dos=OS -Darch=ARCH clean install
build for platform with operating system OS and architecture ARCHThis 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>1.1.0-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.
