Lab Setup Scripts

These are my setup scripts for my baremetal home-lab or cloud-based lab environment. It's designed for a small cluster of VMs/baremetal nodes running kubernetes.

Ansible Setup

To get Ansible, see more at:

• https://docs.ansible.com/ansible/latest/installation_guide/index.html
• https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html

To configure Ansible (e.g. setting up hosts, config SSH and passwords), see:

• https://docs.ansible.com/ansible/latest/user_guide/intro_inventory.html#intro-inventory
• https://docs.ansible.com/ansible/latest/installation_guide/intro_configuration.html

The project added example inventory hosts files and config file. Inventory files should be copied to ~/.ansible/hosts and config file to ~/.ansible, e.g.:

cp ansible/inventory/hosts.example ~/.ansible/hosts
# edit the hosts example

cp ansible/ansible.cfg.example ~/.ansible.cfg
# edit the config example

Ansible Notebook

To use ansible playbook, run:

ansible-playbook k8s/main.yaml

This will attempt to install docker, pre-configure hosts for k8s, and install a k8s cluster in the hosts described in hosts files. Configurations are in ansible/roles/k8s/vars/main.yaml.
