Setting Up Your MacOS Environment for Wallaroo
These instructions have been tested on OSX El Capitan and MacOS Sierra.
There are a few applications/tools which are required to be installed before you can proceed with the setup of the Wallaroo environment.
You'll need a Go 1.9.x compiler. You can get one from the Go website.
Installing Xcode Command Line Tools
If you do not already have Xcode installed, you can run the following in a terminal window:
You can then click “Install” to download and install Xcode Command Line Tools.
Installing a Package Manager, Homebrew
Homebrew is used for easy installation of certain packages needed by Wallaroo.
Instructions for installing Homebrew can be found on their website. This book assumes that you use the default installation directory,
/usr/local. If you choose an alternate installation directory, please configure your shell's
PATH environment variable as needed.
NOTE: For users of the MacPorts package manager, we strongly recommend not using MacPorts. It is extremely difficult to correctly install the compiler toolchain required by Wallaroo using only MacPorts.
If you do not already have Git installed, install it via Homebrew:
brew install git
Installing the Pony Compiler
Now you need to install the Pony compiler
brew update brew install ponyc
Next, you need to install
pony-stable, a Pony dependency management library:
brew update brew install pony-stable
Install Compression Development Libraries
Wallaroo's Kafka support requires a
liblz to be installed.
brew install snappy lz4
You'll need Docker to run the Wallaroo metrics UI. There are instructions for getting Docker up and running on MacOS on the Docker website. We recommend the 'Standard' version of the 'Docker for Mac' package.
Installing Docker will result in it running on your machine. After you reboot your machine, that will no longer be the case. In the future, you'll need to have Docker running in order to use a variety of commands in this book. We suggest that you set up Docker to boot automatically.
Download the Metrics UI
docker pull wallaroo-labs-docker-wallaroolabs.bintray.io/release/metrics_ui:0.4.0
Set up Environment for the Wallaroo Tutorial
If you haven't already done so, create a directory called
~/wallaroo-tutorial and navigate there by running:
cd ~/ mkdir ~/wallaroo-tutorial cd ~/wallaroo-tutorial
This will be our base directory in what follows. If you haven't already cloned the Wallaroo repo, do so now:
git clone https://github.com/WallarooLabs/wallaroo cd wallaroo git checkout 0.4.0
This will create a subdirectory called
Compiling Giles Sender, Data Receiver, and the Cluster Shutdown tool
Giles Sender is used to supply data to Wallaroo applications over TCP, and Data Receiver is used as a fast TCP Sink that can write the messages it receives to STDOUT. The two together are useful when developing and testing applications that use TCP Sources and a TCP Sink.
The Cluster Shutdown tool is used to instruct the cluster to shutdown cleanly, clearing away any resilience and recovery files it may have created.
To compile all three, run
cd ~/wallaroo-tutorial/wallaroo/ make build-giles-all build-utils-cluster_shutdown-all \ build-utils-data_receiver-all
