### About the project:

- This project deploys a kubernetes cluster using [Kubeadm](https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/) on top of Vagrant, all configuration is taken care of using Ansible

- Dynamic storage provisioning is done using **[local-path-provisioner](https://github.com/rancher/local-path-provisioner)** from Rancher

- LoadBalancer implementation is provided using **[MetalLB](https://metallb.universe.tf/)**

- For ingress, **[nginx-ingress-controller](https://kubernetes.github.io/ingress-nginx/deploy/#bare-metal)** is used

- [Weave net CNI](https://www.weave.works/docs/net/latest/kubernetes/kube-addon/#-installation) is used to provide [Network Policies](https://kubernetes.io/docs/concepts/services-networking/network-policies/)

- [Metrics server](https://github.com/kubernetes-sigs/metrics-server) for collecting resource metrics

### Cluster details:

- The cluster is configured as one master and 2 worker nodes as follows:

| Machine Name 	|     Address    	|         FQDN        	|

|:------------:	|:--------------:	|:-------------------:	|

|    master    	| 192.168.100.10 	|  master.example.com 	|

|    worker1   	| 192.168.100.11 	| worker1.example.com 	|

|    worker2   	| 192.168.100.12 	| worker2.example.com 	|

#### Making local-path the default storage class:

```bash

# 1- Enable DefaultStorageClass Admission controller 

vi /etc/kubernetes/manifests/kube-apiserver.yaml

- --enable-admission-plugins=NodeRestriction,DefaultStorageClass

#2- Patch the storage class created by local-path-provisioner

k patch sc local-path -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

```
