I use Vagrant for local development in order to build any development environment. For example, when I need a Kubernetes multi node cluster, I can demonstrate with Vagrant quickly(https://kenanhancer.com/2019/09/08/kubernetes-multi-node-cluster-with-one-updated-vagrant-file/). After I complete my exercise about any technology, I also publish to Vagrant Cloud so that it can be used later without wasting time. But, I am not using only Vagrant, there are different technologies and there are different CLI for them. So, if I don't use one technology sometime, I can forget some important commands. That's why, this post is important for me to remember Vagrant CLI 🙂
Actually there is already a Kubernetes multi node cluster post (https://kenanhancer.com/2018/09/26/kubernetes-multi-node-cluster-with-vagrant/) in this blog. But, this one is different. That post was showing 3 empty virtual server up and run later install tools step by step so it was taking too much time. If you run this Vagrantfile, it will create one master node and 2 worker nodes in Virtualbox. This Vagrantfile is also more configurable. If you need more servers, just append new item in "servers" array in Vagrantfile.
This is the expected result 🙂 As I mentioned at the beginning of the post, one master node and two worker nodes are created in Virtualbox.
