* Installing and configuring yaVDR with Ansible
This is an experimental feature which allows to set up a yaVDR installation based on a normal Ubuntu Server 16.04.x installation using [[http://ansible.com][Ansible]].
* Playbooks
To set up a fully-featured yaVDR installation you can use the yavdr07.yml Playbook:
#+BEGIN_SRC yaml :tangle yavdr07.yml :mkdirp yes :exports none
---
# this playbook sets up a fully featured yaVDR 0.7 installation
#+END_SRC
#+BEGIN_SRC yaml :tangle yavdr07.yml :mkdirp yes
- name: basic setup for PPAs, packages etc.
hosts: yavdr-full
become: true
roles:
- yavdr-common
- yavdr-network
- yavdr-xorg
- grub
#+END_SRC
* Hosts
This playbook can either be used to run the installation on the localhost or any other PC in the network that can be accessed via ssh. Simply add the host names or IP addresses to the hosts file in the respective section:
#+BEGIN_SRC conf :tangle hosts :mkdirp yes
[yavdr-full]
localhost connection=local
[yavdr-headless]
[yavdr-client]
#+END_SRC
* Roles
** yavdr-common
This role is used to set up a basic yaVDR installation. It creates the directories, installs the vdr and other useful packages.
*** Variables
Several variables can be set to customize the configuration.
**** Repositories
You can provide a list of package repositories which provide the necessary packages. Feel free to use own PPAs if you need special customization to the VDR and it's plugins.
#+BEGIN_SRC yaml :tangle roles/yavdr-common/defaults/main.yml
branch: unstable
repositories:
- 'ppa:yavdr/main'
- 'ppa:yavdr/unstable-main'
- 'ppa:yavdr/{{branch}}-vdr'
- 'ppa:yavdr/{{branch}}-kodi'
- 'ppa:yavdr/{{branch}}-yavdr'
#+END_SRC
**** Drivers
Using autodetection to automatically install drivers can be very useful but if you know you need a certain driver, you can simply set it's value to *true*. If you don't want a driver to be installed, set it's value to *false*.
#+BEGIN_SRC yaml :tangle roles/yavdr-common/defaults/main.yml
drivers:
sundtek: auto
ddvb-dkms: auto
#+END_SRC
**** Additional Packages
#+BEGIN_SRC yaml :tangle roles/yavdr-common/defaults/main.yml
extra_packages:
- vim
- tree
- w-scan
#+END_SRC
**** VDR
This section allows you to set the recording directory, the user and group that runs the vdr and it's home directory.
- user :: the vdr user name
- group :: the main group for the user vdr
- uid :: the user id for the user vdr
- gid :: the group id for the group vdr
- home :: the home directory for the user vdr
- recdir :: the recording directory used by VDR
- hide_first_recording_level :: let vdr hide the first directory level of it's recording directory so the content of multiple directories is shown merged together
- safe_dirnames :: replace special characters which are not compatible with Windows file systems and Samba shares
- override_vdr_charset :: workaround for channels with weird EPG encodings, e.g. Sky
#+BEGIN_SRC yaml :tangle roles/yavdr-common/defaults/main.yml
vdr:
user: vdr
group: vdr
uid: 666
gid: 666
home: /var/lib/vdr
recdir: /srv/vdr/video
hide_first_recording_level: true
safe_dirnames: true
override_vdr_charset: false
#+END_SRC

**** Disable default installation of recommended packages
#+BEGIN_SRC yaml :tangle roles/yavdr-common/tasks/main.yml :exports none
