Etienne Champetier 42702dc1a3 Fixes for CentOS 8 (#5213) 
* Fix python3-libselinux installation for RHEL/CentOS 8

In bootstrap-centos.yml we haven't gathered the facts,
so #5127 couldn't work

Minimum ansible version to run kubespray is 2.7.8,
so ansible_distribution_major_version is defined an there is no need to default it

* Restart NetworkManager for RHEL/CentOS 8

network.service doesn't exist anymore
 # systemctl status network
 Unit network.service could not be found.

Without this setting you end up with the following error:
 # yum install docker-ce

README.md

bootstrap-os

Bootstrap an Ansible host to be able to run Ansible modules.

This role will:

  • configure the package manager (if applicable) to be able to fetch packages
  • 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 https://github.com/kubernetes-sigs/kubespray#supported-linux-distributions for a current list.

SSH access to the host.

Role Variables

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 }}).

Per distribution variables

CoreOS

  • coreos_locksmithd_disable: false Whether locksmithd (responsible for rolling restarts) should be disabled or be left alone.

CentOS/RHEL

  • centos_fastestmirror_enabled: false Whether the fastestmirror yum plugin should be enabled.

Dependencies

The kubespray-defaults role is expected to be run before this role.

Example Playbook

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

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