These are my (bdwheele) brainstorming notes for the VM image...I'm still testing this.

VM Configuration

  • Using VirtualBox:
    • 1 Core
    • 3G RAM
    • 500G System Disk (VMDK, Dynamically Allocated)
    • Set network to "Attached to Bridged Adapter"

Base OS Install

  • Centos 6.4 x86-64
  • English language and keyboard
  • hostname: localhost.localdomain (the default)
    • if it is localhost it should set it to the dhcp hostname provided.
  • eth0:
    • Clear "Device MAC address"
    • Connect automatically
    • IPv4 Settings
      • Automatic (DHCP)

  • set timezone to america/indiana/indianapolis, clock uses utc
  • root password is 'changeme'
  • partitioning:
    • custom layout
      • /dev/sda1:  500M ext4 mounted as /boot
      • /dev/sda2:  (remainder of disk) Physical volume
      • Volume Group:  vg_avalon
        • PVs: /dev/sda2
        • LV lv_swap 2G
        • LV lv_root (remainder of disk) ext4 mounted as /
  • Desktop install
  • Reboot / Firstboot
    • Leave all of the defaults, except...
    • Do Not create a new user
  • Log in as root
    • do not check "do not show me this again" to the "you are running as root" dialog.  Just close it.
    • yum update
    • open these ports in the firewall:
      • tcp/22
      • tcp/80
      • tcp/1935
      • tcp/18080
    • clean up eth0 configuration in /etc/sysconfig/network-scripts/ifcfg-eth0:
      • remove UUID
      • remove any DHCP_CLIENT_ID
  • OPTIONAL:
    • shut down the VM
    • at this point the vm is at "baseOS" and can be used as a cloning point

Avalon Install

  • OPTIONAL:
    • clone the baseOS image as puppet-YYYYMMDD
  • Use the installation notes from https://github.com/avalonmediasystem/avalon-installer
    • When setting FACTER_* environment variables, set
      • FACTER_avalon_dropbox_password to "changeme"
      • FACTER_avalon_hostname to "localhost.localdomain"
  • HACK:
    • add avalon to the dropbox group
    • verify that /var/avalon/dropbox is mode 2775

Demo Content

  • OPTIONAL:
    • clone the puppet image as democontent-YYMMDD
  • Get the demo fixtures bundle

    cd /tmp
    wget http://dlib.indiana.edu/~cjcolvar/DemoFixturesBatch.tar.gz     #We need a better place to serve this from
    tar xvzf DemoFixturesBatch.tar.gz
    chown -R avalondrop.dropbox DemoFixturesBatch
    mv DemoFixturesBatch /var/avalon/dropbox

    Monitor progress at http://<whatever>:18080.  

  • Modify /var/www/avalon/current/app/views/catalog/_home_text.html.erb and replace sample content with something like:

     <ul class="thumbnails">
    	<li class="span3"><h5>Featured Video</h5><a href="<%= media_object_path('avalon:1') %>" class="thumbnail" <%= image_tag "thumbnail.name.png", alt: "Featured Video" %></a></li>
    	<li class="span3"><h5>Featured Video</h5><a href="<%= media_object_path('avalon:2') %>" class="thumbnail" <%= image_tag "thumbnail.name.png", alt: "Featured Video" %></a></li>
    	<li class="span3"><h5>Featured Video</h5><a href="<%= media_object_path('avalon:3') %>" class="thumbnail" <%= image_tag "thumbnail.name.png", alt: "Featured Video" %></a></li>
    </ul>

    Thumbnail images should be stored in /var/www/avalon/current/app/assets/images

  • Remove source data

    rm /tmp/DemoFixturesBatch.tar.gz
    rm -rf /var/avalon/dropbox/DemoFixturesBatch

VM Image Prep

 

Adding the demo batch increased the size of the VM download from 3.2G to 7.4G.  Partially its because we've make derivatives and there's really new content on the VM.  But for a bigger reason, any disk space that gets allocated is stored in the image file – the VM doesn't know what's being used and what isn't.  Since we download a largish package, untar it, and create a bunch of temp files, the VM disk image has a bunch of unused (from the OS point of view) disk that it still has to keep track of.  Future research should include how to 'unuse' the disk space.

"zerofree" should do the trick, when combined with vboxmanager modifyhd <name> --compact
