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.

To use this playbook on a Ubuntu Server Installation you need to run the following commands:

sudo apt-get install git
git clone https://github.com/yavdr/yavdr-ansible.git
cd yavdr-ansible
sudo ./install-yavdr.sh

Install script for local usage

if (( $EUID != 0 )); then
    echo "This script must be run using sudo or as root"
    exit
fi

apt-get -y install software-properties-common
# Add repository for ansible
add-apt-repository -y ppa:ansible/ansible
# update packages
apt-get update
# install required packages
apt-get -y install ansible

# TODO: run ansible on local host
ansible-playbook yavdr07.yml -b -i 'localhost_inventory' --connection=local

Playbooks

yavdr07.yml

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

---
# file: yavdr07.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

  roles:

    - samba-config
    - nfs-server
    - grub-config
    - autoinstall-satip
  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:

[localhost]
localhost connection=local

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

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
   workgroup = {{ samba.workgroup }}

# server string is the equivalent of the NT Description field
   server string = %h server (Samba, Ubuntu)

# This will prevent nmbd to search for NetBIOS names through DNS.

#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects
   log file = /var/log/samba/log.%m

# Cap the size of the individual log files (in KiB).
   max log size = 1000

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.
   syslog = 0

# Do something sensible when Samba crashes: mail the admin a backtrace
   panic action = /usr/share/samba/panic-action %d


####### Authentication #######

# "security = user" is always a good idea. This will require a Unix account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html
# in the samba-doc package for details.
#   security = user

# You may wish to use password encryption.  See the section on

TODO autoinstall-drivers

It would be nice to be able to detect if it is suitable to install those drivers:

sundtek for Sundtek devices (local or network connection)

Vendor-IDs:

eb1a:5[1b2] (alte Generation)
2659:* (neuere Sticks)

dddvb-dkms if only newer DD cards are detected

media-build-experimental (up to kernel 4.8) for "old" cards like TT S2-6400 FF

newly merged DD drivers
