vagrant-kombinat

What we provide here, is Kombinat (our flavor of Mesos) in a box. We use CoreOS and Docker Swarm to run Apache Mesos with some additions on top.

😏 Sounds crazy? Because, that it is. Though, Docker Swarm provides us with many of the needed underlying technologies to use Apache Mesos. E.g. overlay networking, service orchestration and declarative infrastructure.

Provisioning may take a while, because the images are pulled in the background

We use the kombinat.yml to provision the Swarm with our Mesos stack.

Setup

Please, do a vagrant plugin update before you continue, as to make sure that you do not rely on some old versions of the Vagrant Ignition Plugin

Please, change the DISCOVERY_URL in config.ign to a working token for etcd, by executing curl -w "\n" 'https://discovery.etcd.io/new?size=3'

vagrant up

sudo echo "172.17.8.2   portainer.kombinat.lan" >> /etc/hosts
sudo echo "172.17.8.2   master.kombinat.lan" >> /etc/hosts
sudo echo "172.17.8.2   marathon.kombinat.lan" >> /etc/hosts
sudo echo "172.17.8.2   chronos.kombinat.lan" >> /etc/hosts
