Vagrant Kubernetes Quick Environment (No High Availability)

NOTE: For This to work without using vagrant ssh (using Kubeconfig export environment), be sure to create a virtualbox host-only interface in same segment as K8s nodes defined in config.yml). For example (in my configuration):

35: vboxnet1: <BROADCAST,MULTICAST,UP,>LOWER_UP> mtu 1500 qdisc fq_codel state >UP group default qlen 1000
   link/ether 0a:00:27:00:00:01 brd ff:ff:ff:ff:ff:ff
   inet 10.10.10.10/24 brd 10.10.10.255 scope global vboxnet1
      valid_lft forever preferred_lft forever
   inet6 fe80::800:27ff:fe00:1/64 scope link 
      valid_lft forever preferred_lft forever

This allows me define in Vagrantfile:

     config.vm.network "private_network",
     ip: node['mgmt_ip'],:netmask => "255.255.255.0",
     virtualbox__intnet: false,
     hostonlyadapter: ["vboxnet1"]

Where 'mgmt_ip' will be configured in config.yml

Usage

1. Download Repo

2. Execute make create

$ make recreate

3. Execute make export

$ make export
export KUBECONFIG=_Wherever_you_are_/tmp_deploying_stage/kubeconfig

4. Export KUBECONFIG varable and enjoy...

$ export KUBECONFIG=/home/frjaraur/Labs/k8s-vagrant/tmp_deploying_stage/kubeconfig

$ kubectl get nodes
