Ansible config for my home lab that is set up with three Orange Pi 5. It sets up a Kubernetes cluster using k3s. It is made specifically for my setup, so it will most likely will not match yours, but feel free to modifiy it or use it as reference.
This config will change over time if I ever need to add some functionality or I need it to be more flexible.
It contains three Ansible playbooks that perform various tasks
First of all you have to create a SSH keypair and set it up in each of the hosts. You will have to add the public key of the keypair to the authorized_keys file of each host
It is very easy. Just have Ansible installed and run
ansible-playbook <playbook_name>This playbook task is to replace the apt sources of the Orange Pi Ubuntu distro for the default Ubuntu ARM apt sources
| Variable name | Default value | Description |
|---|---|---|
| ubuntu_version_codename | jammy | The codename of the Ubuntu version that the hosts have installed |
It will modify the netplan of the hosts in order to set up a static local IP address. For this to work correctly you have to reserve those addresses in you router by setting them as reserved or removing them from the DHCP configuration
For this to work correctly you have to create a host_map.ini file that will map each host IP to the new IP. You also need to add the hosts to the hosts.ini file under the netplan_hosts group. Full example would like like thi:
This playbook has no variables.
# host_map.ini
[ip_map]
192.168.0.20=192.168.0.200
192.168.0.26=192.168.0.211
192.168.0.27=192.168.0.212# hosts.ini
[netplan_hosts]
[email protected]
[email protected]
[email protected]It will set up a Kubernetes cluster using K3S. This playbook can configure nodes and a single master node
Your hosts.ini should contain something as follows for this playbook to work:
[master]
<user>@<ip>
[nodes]
<user>@<ip>
<user>@<ip>
[k3s_cluster:children]
master
nodes
For example:
[master]
[email protected]
[nodes]
[email protected]
[email protected]
[k3s_cluster:children]
master
nodes| Variable name | Default value | Description |
|---|---|---|
| master_ip | jammy | The codename of the Ubuntu version that the hosts have installed |
| extra_server_args | Extra Kubernetes arguments used for the master node | |
| extra_agent_args | Extra Kubernetes arguments used for the nodes | |
| ansible_user | Non-root user that will be used to connect to the hosts | |
| ansible_sudo_pass | Sudo password of the hosts |
