[chef] Re: populating encrypted_data_bag_secret?

[Peter Norton < >]

With 0.10.6 or later, once you're upgraded, add this to ~/.chef/knife.rb:

    encrypted_data_bag_secret "#{current_dir}/data_bag_key"

Of course, if your file is called something besides "data_bag_key"
then change the name of the file above.

I'm not sure if these changes come in with 0.10.6 y default.  If they
don't, or if you've got templates that you've invested time into
customizing, then add this to the template sometime around when it's
creating the client.rb:

# See 
https://github.com/schisamo/chef/commit/d0789ffd97a5cd221d147874c492111d51be9cc1
# The below relies on the config parameter "encrypted_data_bag_secret"
existing in the
# knife config.  This allows secrets to be stored on a less trusted server.
echo -e "`date` \n\n**** \n**** Knifing in the chef encrypted data bag
secret file:\n****\n"
(
cat <<EOP
<%= encrypted_data_bag_secret %>
EOP
) > /tmp/knife-bootstrap/encrypted_data_bag_secret
awk NF /tmp/knife-bootstrap/encrypted_data_bag_secret >
/etc/chef/encrypted_data_bag_secret
chmod 600 /tmp/knife-bootstrap/encrypted_data_bag_secret
chmod 600 /etc/chef/encrypted_data_bag_secret

This chunk depends on /tmp/knife-bootstrap existing in your template.

I don't know for sure what will happen with your current templates if
you've modified them but I suspect that in the common case you're
installing a new gem so all that will happen is that you'll have your
old templates in the old gem directory and the new ones in the new
directory.  You'll probably have to manually reconcile them.
