The goal of this project is to build an automated distributed, scalable kubernetes cluster to deploy projects on it. A multi-node and multi-machine Cluster.
This project contains a Vagrantfile and associated Ansible playbook scripts
to provisioning Kubernetes' cluster using VirtualBox as provider.
Different Vms are created, provisionned with a specific Os system.
Ansible is used as provision system, to auto-configure the Vms as master or worker.
Ansible is only Linux compatible, that's why, the ansible was installed into the different Vms. And executed into it to install the required tools, and run the approprite script.
You need the following installed to use this playground.
Vagrant, version 1.9.3 or better. Earlier versions of vagrant do not work with the Vagrant Ubuntu 16.04 box and network configuration.VirtualBox, tested with Version 5.1.18 r114002- Internet access, this playground pulls Vagrant boxes from the Internet as well as installs Ubuntu application packages from the Internet.
To bring up the cluster, clone this repository to a working directory.
git https://github.com/zouariste/Cross-plateform-Kubernetes-Cluster-Installer.git
Change into the working directory and vagrant up
cd Cross-plateform-Kubernetes-Cluster-Installer
vagrant up
Vagrant will start three machines. Each machine will have a NAT-ed network
interface, through which it can access the Internet, and a private-network
interface in the subnet 192.168.2.50/24. The private network is used for
intra-cluster communication.
The machines created are:
| NAME | IP ADDRESS | ROLE |
|---|---|---|
| Server-1-MASTER | 192.168.2.50 | Cluster Master |
| Server-1-WORKER-1 | 192.168.2.51 | Cluster Worker |
| Server-1-WORKER-2 | 192.168.2.52 | Cluster Worker |
As the cluster brought up the cluster master (master) will perform a kubeadm init and the cluster workers will perform a kubeadmin join. This cluster is
using a static Kubernetes cluster token.
To check the node created ssh to the master node and:
vagrant@Server-1-MASTER:~$ kubectl get nodes
