Installation

On your working machine:

1. Install kubectl
2. Install Ansible

$ python3 -m venv venv
$ . venv/bin/activate
(venv) $ pip install -r requirements

Nodes configuration

Ensure that your nodes are accessible from your working machine via ssh.

Important: nodes should have the same sudo password for ansible become to work properly!

Create hosts.ini with master node and [worker_nodes] section. Example configs:

[master]
192.168.1.1 # replace with your

[worker_nodes]
node1 # entry from ~/.ssh/config
192.168.1.2 # plain ip
node3.mydomain.com # domain name

example.hosts.ini contains example of 2-node cluster with 1 worker node (master is registered at ~/.ssh/config):

master

[worker_nodes]
node1

Running Ansible Playbooks

(venv) $ ansible-playbook ansible/main.yml -K -i hosts.ini

Accessing cluster after installation

Use --kubeconfig=ansible/master_files/admin.conf with kubectl, for example:

$ kubectl --kubeconfig=ansible/master_files/admin.conf get pods --all-namespaces

Repo contains files for dashboard deployment:

$ kubectl --kubeconfig=ansible/master_files/admin.conf apply -R -f kubernetes/
