simple-k8s-cluster

This repository contains anisble roles and a playbook that will provision a basic Kubernetes cluster to the provided master and nodes in the inventory.yaml file.

Pre-requisites

• CentOS7 has been installed on the master and nodes.
• Ensure the hostname of each machine is unique.
• Setup SSH Keys on the master and nodes. The inventory.yaml file has been configured to look for SSH keys at ./ssh-keys.
• Ensure each machine is able to reach the internet.
• Each machine needs to have a static IP.

Provisioning

The below steps are an example of how you can use this playbook to provision a Kubernetes cluster:

1. cd to the root directory of this repository.
2. Edit inventory.yaml to contain the details of the hosts you are provisioning to.
3. Execute ./provision.yaml.

Accessing the cluster

After provisioning, a file will be created at output/kubernetes/config. This is a kube config file that provides admin access to the cluster. Move this file to ~/.kube.

mv output/kubernetes/config ~/.kube/config
