Small ansible role to install Kubernetes with kubeadm

Kubernetes ansible

This ansible role installs kubernetes using kubeadm. CRI-O will be installed beforehand. Cilium CNI will be installed alongside Kubernetes.

Role variables

All role variables and their defaults can be found at defaults/main.yml

Example inventory

Your inventory must contain the groups kube_master and kube_worker. As the group names might suggest worker nodes live in kube_worker and master nodes in kube_master.

all:
  hosts:
    master01.example.com:
    worker01.example.com:
  children:
    kube_master:
      hosts:
        master01.example.com:
    kube_worker:
      hosts:
        worker01.example.com:

Example playbook

---
- hosts: kube_worker kube_master
  vars:
    kube_control_plane_endpoint: 127.0.0.1:6443
  roles:
    - role: freggy.kubernetes
