kdevops_install

===============

kdevops_install is an Ansible role that lets you easily set up everything you need for kdevops in one go. Usually, you would have to manually update a requirements file, a playbook, and a Makefile for each role, which is prone to errors and doesn’t let you easily manage a complete release of kdevops.

By using a single role to deploy kdevops, we can quickly refer to a real kdevops release that includes a set of Ansible roles.

Requirements

The following operating systems are supported:

OS X
Linux

Ansible Role Variables

force_kdevops_playbook_dir: Use this in your project if your playbooks are not located in the standard playbooks directory.

Dependencies

None.

Enabling libvirt as a Regular User

kdevops aims to allow a regular user (the one using kdevops) to run libvirt commands without needing special permissions. This is managed by the libvirt-user Ansible role. We use this role twice: first with only_verify_user set to False to allow the user to run libvirt commands, and then with only_verify_user set to True to check if the user needs to log out and log back in, which is necessary if they were added to a group.

The install_kdevops role takes care of this process for you. It first enables libvirt for regular users in the kdevops_vagrant_deps by running the libvirt-user role. Then, at the kdevops_verify_vagrant_user stage, it checks if the user needs to log out and in again.

Example Playbook

Here’s an example playbook used in the kdevops project, specifically in the kdevops/playbooks/kdevops_vagrant.yml file:

---
- hosts: localhost
  roles:
    - role: kdevops_install

In this example, we use localhost because we are setting up the Vagrantfile locally in the kdevops/vagrant/ directory. You can use a different host if needed.

Extra Ansible Arguments

All kdevops Ansible roles look for additional argument files to set the Ansible --extra-vars=@file option, which will override all variables. These files are specific to kdevops but use common names. Ansible doesn’t automatically find these files, so we have added tasks to every kdevops role to look for them. The search order for these files is:

../extra_vars.yml
../extra_vars.yaml
../extra_vars.json

kconfig Support

There are many targets that let you use a build system with a variability modeling language like kconfig to configure what you want to enable. This is demonstrated in the upstream kdevops project.
