4 node alpine docker swarm vagrant

First

Since we are using alpine linux we must install the alpine plugin for vagrant.

To make this easy for you you can run

$ ./init-vagrant.sh

When it's not your first run and there is no more a need to install docker you can just do vagrant up

$ vagrant up

ssh into one of the nodes

$ vagrant ssh manager-1 
$ vagrant ssh manager-2
$ vagrant ssh node-1
$ vagrant ssh node-2

run the following command to initialize the 4 node swarm

./init-swarm.sh
