Introduction

debops.cryptsetup allows you to configure encrypted filesystems on top of any given block device using dm-crypt/cryptsetup and LUKS. A random keyfile generated on the Ansible controller will be used for the encryption by default. It is your responsibility that the keyfile is kept secure for this to make sense. For example by storing the keyfile on an already encrypted filesystem (both on the Ansible controller and the remote system).

Features

  • Create a random keyfile or use an already existing keyfile.
  • Manage /etc/crypttab and /etc/fstab and mount point directories.
  • Create a LUKS header backup and store it on the Ansible controller.
  • Decrypt and mount an encrypted filesystem and never store any key material on persistent storage on the remote system. You might need to take care of your Swap space yourself for this!
  • Setup an encrypted swap space (with random key or with persistent key).
  • Setup filesystems using a random key on boot.
  • cryptsetup LUKS and plain mode.
  • Multiple ciphers and corresponding keys to encrypt one filesystem.

Installation

This role requires at least Ansible v2.1.4. To install it, run:

ansible-galaxy install debops.cryptsetup
