  • install Python
  • install the necessary packages to use Ansible's package manager modules
  • set the hostname of the host to {{ inventory_hostname }} when requested

Requirements

A host running an operating system that is supported by Kubespray. See Supported Linux Distributions for a current list.

SSH access to the host.

Variables are listed with their default values, if applicable.

General variables

  • http_proxy/https_proxy The role will configure the package manager (if applicable) to download packages via a proxy.

  • override_system_hostname: true The role will set the hostname of the machine to the name it has according to Ansible's inventory (the variable {{ inventory_hostname }}).

Example Playbook

Remember to disable fact gathering since Python might not be present on hosts.

  gather_facts: false  # not all hosts might be able to run modules yet
  roles:
     - kubespray-defaults
     - bootstrap-os
