OpenWhisk Command-line Interface (CLI) is a unified tool that provides a consistent interface to interact with OpenWhisk services.
The OpenWhisk CLI is available on the releases page. We currently have binaries available for Linux, Mac OS and Windows under i386 and amd64 architectures. Linux versions are also available under Linux on Z, Power and 64-bit ARM architectures. You can download the binary, which fits your local environment.
The OpenWhisk CLI is written in the Go language. You have two options to build the binary locally:
Note: For those who may have used the Gradle build previously, it has been re-engineered to no longer required Docker or Go to be pre-installed on your system. Using the gogradle plugin, Gradle now uses a preexisting Go environment to build if it can be located, or downloads and installs an environment within the build directory.
To build with Gradle, open an terminal, go to the directory of OpenWhisk CLI home directory, and build the binary via the following command under Linux or Mac:
$ ./gradlew compile -PnativeCompile
or run the following command for Windows:
$ ./gradlew.bat compile -PnativeCompile
After the build, you can find the binary
wsk.exe in the build folder under the OpenWhisk CLI home directory. In addition, it is also available under the folder
build/<os>-<architecture>/. For example, if your local operating system is Mac, and the CPU architecture is amd64, the binary can be found at
If you would like to build the binaries available for all the operating systems and architectures, run the following command:
$ ./gradlew compile
The build script will place the binaries into the folder
build/<os>-<cpu arc>/ for each operating system and CPU architecture pair. The build supports both amd64 and 386 for Linux, Mac and Windows operating systems, as well as Power, 64-bit ARM, and S390X architectures for Linux.
A binary compatible with the local architecture will be placed at
build\wsk.exe on Windows).
To specify a build for specific architectures, you can provide a comma or space-delimited list of hyphenated os-architecture pairs, like this:
$ ./gradlew compile -PbuildPlatforms=linux-amd64,mac-amd64,windows-amd64
The build library understands most representations of most Operating Systems.
Tests can be run using the Gradle script:
$ ./gradlew goTest -PgoTags=unit $ ./gradlew goTest -PgoTags=native
Integration tests are best left to the Travis build as they depend on a fully functional OpenWhisk environment.
Make sure that you have Go installed, and
$GOPATH is defined in your Go development environment.
Then download the source code of the OpenWhisk CLI and the dependencies by typing:
$ cd $GOPATH $ go get github.com/apache/openwhisk-cli $ cd $GOPATH/src/github.com/apache/openwhisk-cli
The CLI internationalization should be generated dynamically using the bindata tool:
$ go get -u github.com/jteeuwen/go-bindata/... $ go-bindata -pkg wski18n -o wski18n/i18n_resources.go wski18n/resources
The project includes a
vendor/vendor.json and you can lock down dependencies for a clean build of the CLI by populating the
$ go get -u github.com/kardianos/govendor # Install govendor tool $ govendor sync # Download and install packages with specified dependencies.
NOTE: As a temporary workaround, you have to remove a redundant instance of
spf13/cobra in the vendor folder. See this issue for details.
$ rm -rf vendor/github.com/spf13
Now you can build the binary.
$ go build -o wsk
If you would like to build the binary for a specific operating system, you may add the arguments
GOARCH into the Go build command.
GOOS can be set to
For example, run the following command to build the binary for Linux:
$ GOOS=linux GOARCH=amd64 go build -o wsk-$GOOS-$GOARCH
If it is executed successfully, you can find your binary
wsk directly under OpenWhisk CLI home directory.
You can run unit tests as well (although note the majority of the tests today are not in Go).
$ cd commands $ go get github.com/stretchr/testify/assert $ go test -tags=unit -v
When you have the binary, you can copy the binary to any folder, and add folder into the system PATH in order to run the OpenWhisk CLI command. To get the CLI command help, execute the following command:
$ wsk --help
To get CLI command debug information, include the
--debug flag when executing this command.
Travis CI is used as a continuous delivery service for Linux and Mac. Currently Travis CI supports the environments of Linux and Mac, but it is not available for Windows. We will add support of AppVeyor CI in future to run test cases and build the binary for Windows.
