Proxy fixes (#5869) 
* Fix proxy and module_hotfixes

On CentOS 8 with proxy ansible render inline `proxy` and `module_hotfixes` options.

For example:

`proxy=http://127.0.0.1:3128module_hotfixes=True`

But expected result:

```
proxy=http://127.0.0.1:3128
module_hotfixes=True
```

* Use ini_file module for work with ini files

* Prevent duplicates proxy= option in /etc/yum.conf

Module `lineinfile` is weak, use most powerful module `ini_file` and add or remove `proxy=` when `http_proxy` is defined or not.

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
