• OPTIONAL:
  
  • clone the puppet image as democontent-YYMMDD
• Register the archivist1@example.com user in Avalon, and log in as that user.
  
  • this account is removed when the system is prepared for delivery.

• Get the demo fixtures bundle

  Code Block
  cd /tmp wget http://www.avalonmediasystem.org/downloads/AvalonDemoBatchDemoFixturesBatch.tar.gz tar xvzf AvalonDemoBatchDemoFixturesBatch.tar.gz chown -R avalondrop.dropbox AvalonDemoBatchDemoFixturesBatch mv AvalonDemoBatchDemoFixturesBatch /var/avalon/dropbox

  Monitor progress in Matterhorn (at http://<whatever>:18080 using the default username/password) or within Avalon.

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

  Code Block
  language html/xml
  <ul class="thumbnails"> <li class="span3"><h5>Featured Video</h5><a href="<%= media_object_path('avalon:1') %>" class="thumbnail" ><%= image_tag "AvalonDemoThumbnailsDemoFixturesThumbnails/organScreenshot.jpg", alt: "Featured Video" %></a></li> <li class="span3"><h5>Featured Video</h5><a href="<%= media_object_path('avalon:2') %>" class="thumbnail" ><%= image_tag "AvalonDemoThumbnailsDemoFixturesThumbnails/lunchroom_manners.jpg", alt: "Featured Video" %></a></li> <li class="span3"><h5>Featured Audio</h5><a href="<%= media_object_path('avalon:3') %>" class="thumbnail" ><%= image_tag "AvalonDemoThumbnailsDemoFixturesThumbnails/gustav_mahler.jpg", alt: "Featured Audio" %></a></li> </ul>

  Thumbnail images can be downloaded from http://www.avalonmediasystem.org/downloads/AvalonDemoThumbnailsDemoFixturesThumbnails.tar.gz and should be unpacked into /var/www/avalon/current/app/assets/images.  The values "avalon:1" to "avalon:3" should be changed to the appropriate container IDs.

• Reload the avalon application by running

  Code Block
  touch /var/www/avalon/current/tmp/restart.txt

  and verify the changes are correct.

• Fix the section titles of the audio example:

  • edit the item

  • click on the "Manage Files" tab
  • change the filenames to "CD 1" (for agz3068a.wav) and "CD 2" (for agz3068b.wav)
  • click Save
• Fix access permissions on all three items:
  
  • edit each item
    
    • click on the "Access Control" tab
    • click on the "Available to the general public" radio button
    • click Save
    • Click the 'Publish" button if it is available on the item view (Lunchroom Manners).

• Remove source data

  Code Block
  rm /tmp/AvalonDemoBatchDemoFixturesBatch.tar.gz rm -rf /var/avalon/dropbox/AvalonDemoBatchDemoFixturesBatch

VM Image Prep

• OPTIONAL:
  
  • clone the latest democontent image as dist-YYMMDD
• Install avalon-vm-1.0-1.noarch.rpm to install the firstboot changes and tools
  
  • Binary Package:  http://www.avalonmediasystem.org/downloads/avalon-vm-2.0-1.noarch.rpm
  • Source Package: http://www.avalonmediasystem.org/downloads/avalon-vm-2.0-1.src.rpm
• If IPv6 was disabled during install, re-enable it by removing the lines added to /etc/sysctl.conf during BaseOS.  If these lines are not removed, email will not work.
• Prepare the disk for compacting
  

  • clean up anything that's left over from the build process

    Code Block
    rm -rf /root/Downloads/* /var/avalon/dropbox/* /home/makerpm/rpmbuild /opt/staging /root/avalon-installer-flat /root/flat.tar.gz yum clean all swapoff /dev/mapper/vg_avalon-lv_swap; dd if=/dev/zero of=/dev/mapper/vg_avalon-lv_swap bs=1M; mkswap /dev/mapper/vg_avalon-lv_swap

  • deleted files still take up space on the disk image.  The disk image (as of 4/24/13) is roughly 12G in size, with 7.8G of actual data.  Write zeros to a file until the disk is full to clear out the sectors which are unallocated but had data at one point.  Since the .VDI image is sparsely allocated, the disk image size will actually grow less that 1G even though nearly 500G has been written.

    Code Block
    dd if=/dev/zero of=/tmp/foo bs=1M oflag=direct; rm /tmp/foo

• run /usr/share/avalon/dist-prep to prepare the machine for release
• clear the command line history  (history -cw)
• shutdown the VM
• Compact the disk image
  

  • On the host run:

    Code Block
    VBoxManage modifyhd avalon-vm-disk-YYMMDD.vdi --compact

• Export the appliance
  • Disable USB 2.0 in the VM to avoid a warning when users don't have the VirtualBox extensions loaded.

  • VM Settings:

    Name	Value
    Name	avalon-vm
    Product	Avalon Media System
    Product-URL	http://avalonmediasystem.org
    Version	R1

• copy the OVA to the distribution point
  • Make sure to set the avalon-vm.ova symlink to the current release
  • Set the permissions to 644 (they're 600 by default)
