mesos-hello-world

Very simple hello world mesos framework to demonstrate http://github.com/containersolutions/mini-mesos.

NOTE - This project has been integrated into minimesos

Introduction

This project creates a very simple Apache Mesos framework, with dockerized scheduler and exector containers. The goal is to use the scheduler to start a number of dummy "webapps" (webservers that show "Hello world" on /) then test the framework using the mini-mesos project.

Non-linux users

If you are developing on an envrionment other than Linux, then you will need to use a VM. We use docker-machine. You will then need to export the docker settings. E.g.:

docker-machine create -d virtualbox --virtualbox-memory 4096 --virtualbox-cpu-count 2 dev
eval "$(docker-machine env dev)"

To run the system tests, non-linux users will have to route all communications to the docker containers via the VM IP address:

sudo route -n delete 172.17.0.0/16 $(docker-machine ip dev) ; sudo route -n add 172.17.0.0/16 $(docker-machine ip dev)

Compiling

To build the project (you will need to build the docker images before you run the system tests) simply run:

./gradlew build -x test

System test

To run the system tests, run:

./gradlew :system-test:test

It is also possible to run the system test in Idea, by setting the JUnit environmental variables to point to your docker daemon.
