Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place.

This cookbook contains an LWRP to manage one-time-use encrypted filesystem
using the cryptsetup package in Debian and Ubuntu. On each boot, a
filesystem-in-a-file will be created, mounted as a loop device, encrypted
via cryptsetup with a randomly-generated key that isn't stored anywhere,
and mounted for use. It isn't necessary to reboot for the filesystem
resources to become available, but they will be created anew each time a
machine reboots.

The intended purpose of this cookbook is for deploying servers which will
handle sensitive information on untrusted systems or cloud deployments, so
that the filesystems themselves will not be readable outside the running
instance. Information stored in the encrypted filesystem will be irretrievable
after reboot.



Tested on:
* Debian 6.0
* Ubuntu 12.04

This cookbook will only work on Debian or Ubuntu systems if the cryptsetup
package is available. The cryptsetup package will be installed if it's not
already present.


  • node['encryptfs'['uninstall_cryptsetup_iflast'] - Sets the cookbook to remove the cryptsetup packages after the last filesystem is removed from /etc/crypttab. Default is false, to leave the packages installed. Only the cryptsetup and cryptsetup-bin packages will be uninstalled if this is true.



The default recipe won't do anything.


This represents an example of creating a few small encrypted filesystems. You
really should be using this only as an LWRP.


This cookbook includes an LWRP, encryptfs, for managing one-time-use
encrypted filesystems.

encryptfs "data" do
  size 100
  filepath "/cryptfs"
  mountpath "/usr/local/cryptdata"
  action :create

The size is specified in megabytes. The filepath is where the file of
that size is to be created in your existing filesystems. That file will
become a loop device containing the encrypted block data. The mountpath will
be where the encrypted filesystem is to be mounted. The LWRP supports both
:create and :delete actions.


Put the following in your cookbook's metadata.rb file to include this LWRP:

depends "encryptfs"

The following added to your recipes will create an encrypted filesystem:

encryptfs "data" do
  size 100
  filepath "/cryptfs"
  mountpath "/usr/local/cryptdata"
  fstype "ext4"
  action :create

The following added to your recipe will delete an encrypted filesystem:

encryptfs "data" do
  action :delete
