Installing Protobuf

In this recipe, we will be installing Protobuf to generate Golang structures used in communication with Mesos.

Getting ready

Install Golang, Protobuf, and the Golang Protobuf bindings:

sudo add-apt-repository ppa:ubuntu-lxc/lxd-stable
sudo apt-get update
sudo apt-get install golang git
export GOPATH=~/go
export PATH=$PATH:$GOPATH/bin
sudo apt-get install protobuf-compiler
go get -u github.com/golang/protobuf/{proto,protoc-gen-go}

How to do it...

1. Create a project directory and go there:

mkdir -p $GOPATH/src/simple-scheduler
cd $GOPATH/src/simple-scheduler

2. Download the Mesos protobuf message definitions:

wget https://raw.githubusercontent.com/apache/mesos/170ac/include/mesos/v1/mesos.proto
wget https://raw.githubusercontent.com/apache/mesos/170ac/include/mesos/v1/scheduler/scheduler.proto

3. Tweak them to our needs. Change the default package of generated bindings to one that matches Golang. We will keep the whole project in one main package and the generated bindings should fit in...
