# A Short Demo of the Magic of Chef-Vault
##Set up the magic show from a shell on your own workstation
###Put the bunny in the hat
echo "bunny" > tophat
###Put the hat in the magic show
export assistant=aug24 #Change this to your chef id
export role=magician #Change this to the role you need to pass the secret to
knife vault create magicshow hat \ #Create a hat object in a data bag called magicshow
--mode client \ #Talk to the chef server rather than local
--file tophat \ #Use the hat (file) we put the bunny in
--search "role:${role}" \ #Encrypted for all *current* nodes with the magician role
--admins "${assistant}" #Encrypted for the assistant
###Check the magic show is on the chef server
knife data bag list
knife vault list
###Check the hat is there (and that nobody can see what's in it)
knife data bag show magicshow hat
###Check you can see what's in it
knife vault show magicshow hat file-content --mode client
##'Hop' on to a node with a role of 'magician'
###Install required software
sudo apt-get install ruby-dev --yes
sudo gem install chef-vault --no-ri --no-rdoc
###Get the bunny back out of the hat!
sudo chef-shell --client <<EOF
require 'chef-vault'
puts ChefVault::Item.load('magicshow', 'hat')['file-content']
EOF
If you are on a node which is not a magician, an exception will be thrown,
and the node cannot see what is in the hat.
#Finally, do a disappearing act.
###Make the hat disappear...
knife vault delete magicshow hat --mode client
###Make the entire magic show disappear...
knife data bag delete magicshow
###Thank you!
