Setting Up Your Ubuntu Environment for Wallaroo

These instructions have been tested for Ubuntu Artful, Trusty, and Xenial releases.

There are a few applications/tools which are required to be installed before you can proceed with the setup of the Wallaroo environment.

Memory requirements

In order to compile the Wallaroo example applications, your system will need to have approximately 6 GB working memory (this can be RAM or swap). If you don't have enough memory, you are likely to see that the compile process is Killed by the OS.

Installing git

If you do not already have Git installed, install it:

sudo apt-get install git

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 (this will create a subdirectory called wallaroo):

git clone https://github.com/WallarooLabs/wallaroo
cd wallaroo
git checkout 0.5.1

Install Go

You'll need a Go 1.9.x compiler. You can get one from the Go website.

Update apt-get

Ensuring you'll have the latest available packages:

sudo apt-get update

Install make

sudo apt-get update
sudo apt-get install -y build-essential

Install libssl-dev

sudo apt-get install -y libssl-dev

Install GCC 5 or Higher

If you have at least GCC 5 installed on your machine, you don't need to do anything. If you have gcc 4.9 or lower, you'll need to upgrade. You can check your gcc version by running:

gcc --version

To upgrade to GCC 5:

sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test

then

sudo apt-get update
sudo apt-get install -y gcc-5 g++-5

And set gcc-5 as the default option:

sudo update-alternatives --install /usr/bin/gcc gcc \
  /usr/bin/gcc-5 60 --slave /usr/bin/g++ g++ /usr/bin/g++-5

Add ponyc and pony-stable apt-key keyserver

In order to install ponyc and pony-stable via apt-get the following keyserver must be added to the APT key management utility.

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys "D401AB61 DBE1D0A2"

Installing ponyc

Now you need to install Pony compiler ponyc. Run:

echo "deb https://dl.bintray.com/pony-language/ponyc-debian pony-language main" | sudo tee -a /etc/apt/sources.list
sudo apt-get update
sudo apt-get -V install ponyc=0.24.4

Installing pony-stable

Next, you need to install pony-stable, a Pony dependency management library. Navigate to a directory where you will put the pony-stable repo and execute the following commands:

echo "deb https://dl.bintray.com/pony-language/pony-stable-debian /" | sudo tee -a /etc/apt/sources.list
sudo apt-get update
sudo apt-get -V install pony-stable

Install Compression Development Libraries

Wallaroo's Kakfa support requires libsnappy and liblz to be installed.

Artful and Xenial Ubuntu:

sudo apt-get install -y libsnappy-dev liblz4-dev

Trusty Ubuntu:

Install libsnappy:

sudo apt-get install -y libsnappy-dev

Trusty Ubuntu has an outdated liblz4 package. You will need to install from source like this:

cd ~/
wget -O liblz4-1.7.5.tar.gz https://github.com/lz4/lz4/archive/v1.7.5.tar.gz
tar zxvf liblz4-1.7.5.tar.gz
cd lz4-1.7.5
make
sudo make install

Install Docker

You'll need Docker (CE or EE) to run the Wallaroo metrics UI. There are instructions for getting Docker up and running on Ubuntu on the Docker website.

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.

All of the Docker commands throughout the rest of this manual assume that you have permission to run Docker commands as a non-root user. Follow the Manage Docker as a non-root user instructions to set that up. If you don't want to allow a non-root user to run Docker commands, you'll need to run sudo docker anywhere you see docker for a command.

Download the Metrics UI

sudo docker pull wallaroo-labs-docker-wallaroolabs.bintray.io/release/metrics_ui:0.5.1

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.

The Cluster Shrinker tool is used to tell a running cluster to reduce the number of workers in the cluster and to query the cluster for information about how many workers are eligible for removal.

Compiling Giles Sender, Data Receiver, Cluster Shutdown, and Cluster Shrinker tools

Change to the root Wallaroo directory:

cd ~/wallaroo-tutorial/wallaroo/

Compiling Giles Sender, Data Receiver, and the Cluster Shutdown tool on Artful

Due to ponyc's dependence on PIC on Artful Ubuntu, all applications must be compiled with the PONYCFLAGS="--pic" flag, like so:

make build-giles-sender-all build-utils-all PONYCFLAGS="--pic"

Compiling Giles Sender, Data Receiver, and the Cluster Shutdown tool on Trusty and Xenial

make build-giles-sender-all build-utils-all
