我们需要以下的几个软件：

• Docker 1.12.0
• Java 8
• Scala 2.11
• Ansible 2.3.0.0

为此需要执行以下的这行命令：

echo '
# install homebrew
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
# install cask
brew tap caskroom/cask
# install java 8
brew cask install java
# install scala
brew install scala
# install pip
sudo easy_install pip
# install script prerequisites
sudo -H pip install docker==2.2.1 ansible==2.3.0.0 jinja2==2.9.6 couchdb==1.1 httplib2==0.9.2 requests==2.10.0' | bash

然后运行起你的 Docker，再到 openwhisk 的目录下，执行：

$ ./gradlew distDocker

期间会下载一些 Jar 包，以及拉 Docker 的镜像：

期间会下载不同的运行环境：

再用 CLI 来执行操作就可以了：

$ bin/wsk action invoke /whisk.system/utils/echo -p message hello --result
{
    "message": "hello"
}
