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 Ansible.

This Manual is written in org-mode for Emacs and can rewrite the complete ansible configuration if you call org-babel-tangle from within emacs.

Playbooks

yavdr07.yml

The yavdr07.yml playbook sets up a fully-featured yaVDR installation:

---
# file: yavdr07.yml
# this playbook sets up a complete yaVDR 0.7 installation

- name: set up yaVDR
  hosts: all
  become: true
  roles:
     - yavdr-common   # install and configure the basic system
     - vdr            # install vdr and related packages
     - yavdr-network  # enable network client capabilities
     - samba-install  # install samba server
     - samba-config   # configure samba server
     - nfs-server     # install nfs server
     #- nfs-config     # configure nfs server
     - yavdr-xorg     # graphical session
     - yavdr-remote   # remote configuration files, services and scripts
     - grub-config    # configure grub
     - autoinstall-satip # install vdr-plugin-satip if a Sat>IP server has been found
     - autoinstall-targavfd
     - autoinstall-imonlcd
     #- template-test

  handlers:
    - include: handlers/main.yml

yavdr07-headless.yml

For a headless server installation yavdr07-headless.yml is a good choice

---
# file: yavdr07-headless.yml
# this playbook set up a headless yaVDR 0.7 installation

- name: set up a headless yaVDR server
  hosts: all
  become: true
  roles:
    - yavdr-common
    - vdr
    - yavdr-network
    - samba-server
    - samba-config
    - nfs-server
    - nfs-config
    - grub-config
  handlers:
    - include: handlers/main.yml

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:

[yavdr-full]
localhost connection=local
#192.168.1.116

[yavdr-headless]

[yavdr-client]

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.

default variables

This section is for reference only, please use the files in global_vars for customizations.

---
# file: roles/yavdr-common/defaults/main.yml

Repositories

You can set 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.

branch: unstable
repositories:
  - 'ppa:yavdr/main'
  - 'ppa:yavdr/unstable-main'
  - 'ppa:yavdr/{{branch}}-vdr'
  - 'ppa:yavdr/{{branch}}-kodi'
  - 'ppa:yavdr/{{branch}}-yavdr'

Drivers

Automatically installed 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.

drivers:
  sundtek: auto
  ddvb-dkms: auto

Additional Packages

Add additional packages you would like to have on your installation to this list

  extra_packages:
      - vim
      - tree
      - w-scan

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

vdr:
    user: vdr
    group: vdr
    uid: 666
    gid: 666
    home: /var/lib/vdr
    recdir: /srv/vdr/video
    hide_first_recording_level: false
    safe_dirnames: true
    override_vdr_charset: false
