Getting started

The following steps were designed for making easy the use of this repository using make.

Cloning repository

We are gonna start cloning this repo: git clone https://github.com/AudelDiaz/kubeadm-cluster.git

Running cluster

When you run the cluster at the first time vagrant creates VM's defined in Vagrantfile and provisions them using Ansible.

make deploy

Accessing VM

For ssh access you just need to use VM name.

vagrant ssh master
vagrant ssh worker

Destroying cluster

When you finish you can destroy the testing environment and recover machine resources.

make clean

Other extra commands

• make start: Start VM's
• make stop : Stop VM's
• make install : Install kubernetes cluster
• make tools: Install Metrics Server and Weave Scope
• make copy-config: Copy master ~/.kube/config to host machine. (If you have a previews setup, make a backup and delete the original to create a new one.)

Running Weave Scope

If you have installed monitoring tools using make tools and copied .kube/config to your host with make copy-config, you are able to open Weave Scope with this command:

kubectl port-forward -n weave "$(kubectl get -n weave pod --selector=weave-scope-component=app -o jsonpath='{.items..metadata.name}')" 4040
