# 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.
|
||
|
|
This is currently implemented for CentOS/RHEL (`http_proxy` only) as well as Debian and Ubuntu (both `http_proxy` and `https_proxy` are respected)
|
||
|
|
|
||
|
|
* `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](https://wiki.centos.org/PackageManagement/Yum/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
