Kubeclust sets up a kubernetes 1.13.2 cluster on three VirtualBox virtual machines (one master and two workers) running Ubuntu 18.04 LTS using kubeadm.
- Virtual environment with Python3
- Virtualbox
- Vagrant
In the virtual environment, run
$ pip install -r requirements.txt
Run vagrant up
to bring up three virtual machines.
The hostnames and IP addresses of the machines are as follows:
kubemaster — 192.168.99.20
worker1 – 192.168.99.21
worker2 – 192.168.99.22
In the virtual environment created earlier, run
$ make cluster
As soon as it is done, you can ssh into kubemaster to see the nodes and the pods in the cluster. They may take a while to get ready.
vagrant@kubemaster:~$ kubectl get nodes
NAME STATUS ROLES AGE VERSION
kubemaster Ready master 54s v1.13.2
worker1 Ready <none> 27s v1.13.2
worker2 Ready <none> 27s v1.13.2
vagrant@kubemaster:~$ kubectl get pods --all-namespaces

$ make clean
This will drain the nodes, make sure that they are empty before shutting them down and reset all kubeadm installed state.
