Write a Scala Mesos Framework in 7 Steps

This is a giter8 template. The result of applying this template is a bare-bones Apache Mesos framework in Scala using SBT for builds and Vagrant for testing on a singleton cluster.

Before we start

• You need git
• You need giter8
• You need SBT
• You need vagrant
• You need virtual box

Procedure

1. Clone this giter8 template

    $ g8 mesosphere/scala-sbt-mesos-framework
    package [com.domain]: io.mycompany   
    name [My Mesos Framework]: My Great Framework
    
    Template applied in ./my-great-framework
   

2. Change into the new project directory

    $ cd my-great-framework
   

3. Inspect the template output with your favorite editor. The build definition is in project/Build.scala and the framework implementation is in src/main/scala/.

4. Edit the framework's configuration file (src/main/resources/application.conf) to reflect the master's private IP address on the virtual machine

    io.mycompany {
      mesos {
        master = "10.141.141.10:5050"
      }
    }
   

5. Create and start a virtual machine running the Mesos master and the Mesos slave

    $ vagrant up
   

6. Run your new framework with SBT

    $ sbt run
   

7. Observe STDOUT as your framework registers with the Mesos master and begins receiving resource offers
