One way to develop or deploy OpenWhisk on a Mac is to use docker-machine which runs the Docker daemon inside a virtual machine accessible from the Mac host.
The following are required to build and deploy OpenWhisk from a Mac host:
- Oracle VM VirtualBox
- Docker 1.12.0 (including
docker-machine) - Java 8
- Scala 2.11
- Ansible 2.1.2.0
Tip Versions of Docker and Ansible are lower than the latest released versions, the versions used in OpenWhisk are pinned to have stability during continues integration and deployment.
Homebrew is an easy way to install all of these and prepare your Mac to build and deploy OpenWhik. The following shell command is provided for your convenience to install brew with Cask and bootstraps these to complete the setup. Copy the entire section below and paste it into your terminal to run it.
echo '
# install homebrew
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
# install cask
brew tap caskroom/cask
# install virtualbox
brew cask install virtualbox
# install docker 1.12.0
brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/33301827c3d770bfd49f0e50d84e0b125b06b0b7/Formula/docker.rb
# install docker-machine
brew install docker-machine
# install java 8
brew cask install java
# install scala
brew install scala
# install pip
sudo easy_install pip
# install ansible
sudo -H pip install ansible==2.1.2.0
# the following is required for running tests
sudo -H pip install jsonschema' | bash
It is recommended that you create a virtual machine whisk with at least 4GB of RAM.
docker-machine create -d virtualbox \
--virtualbox-memory 4096 \
--virtualbox-boot2docker-url=https://github.com/boot2docker/boot2docker/releases/download/v1.12.0/boot2docker.iso \
whisk # the name of your docker machine
The Docker virtual machine requires some tweaking to work from the Mac host with OpenWhisk.
The following script will disable TLS, add port forwarding
within the VM and routes 172.17.x.x from the Mac host to the Docker virtual machine.
Enter your sudo Mac password when prompted.
cd /your/path/to/openwhisk
./tools/macos/tweak-dockermachine.sh
The final output of the script should resemble the following two lines.
Run the following:
export DOCKER_HOST="tcp://192.168.99.100:4243" # your Docker virtual machine IP may vary
The Docker host reported by docker-machine ip whisk will give you the IP address.
Currently, the system requires that you use port 4243 to communicate with the Docker host
from OpenWhisk.
Ignore errors messages from docker-machine ls for the whisk virtual machine, this is due
to the configuration of the port 4243 vs. 2376
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
whisk - virtualbox Running tcp://192.168.99.100:2376 Unknown Unable to query docker version: Cannot connect to the docker engine endpoint
To verify that docker is configure properly with docker-machine run docker ps, you should not see any errors. Here is an example output:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
You may find it convenient to set these environment variables in your bash profile (e.g., ~/.bash_profile or ~/.profile).
export OPENWHISK_HOME=/your/path/to/openwhisk
export DOCKER_HOST=tcp://$(docker-machine ip whisk):4243
The tweaks to the Docker machine persist across reboots. However one of the tweaks is applied on the Mac host and must be applied again if you reboot your Mac. Without it, some tests which require direct communication with Docker containers will fail. To run just the Mac host tweaks, run the following script. Enter your sudo Mac password when prompted.
cd /your/path/to/openwhisk
./tools/macos/tweak-dockerhost.sh
cd /your/path/to/openwhisk
./gradlew distDocker
Tip Using gradlew handles the installation of the correct version of gradle to use.
