The debops-padlock command

An optional script that allows you to encrypt your secrets directory using EncFS and GPG.

  1. Make sure you have encfs installed, ie. apt-get install encfs

  2. Make sure you have a GPG keypair

  3. Make sure $project_dir/ansible/secret/ is empty

  4. Run debops-padlock init and enter your GPG password unless you have an agent

  5. Run debops-padlock unlock

  6. Do something that would result in adding files to secret/, such as touching a file

  7. Run debops-padlock lock

  8. Confirm you have 1 or more sub-folders or files in .encfs.secret/

The above steps performed the following tasks:

  • Setup a project directory to use an encrypted secrets directory

  • Added files to be encrypted

  • Locked it, which unmounts secret/ -- it is now secure

That sounds annoying, can it be done better?

When running any play book through the debops script, it will automatically take care of unlocking/locking it after the run finishes successfully or errors out.

There is a catch, make sure you always use debops to run your plays because if you run ansible-playbook directly the unlock/lock process will not happen automatically. It may change your passwords and whatever else you have stored.

If you use the debops script you won't have to worry about anything being changed.

Delete your secrets

Since EncFS mounts secret/ you need to unlock it first. If you forgot to unlock it first then you will get a device is busy error.

You can fix this by unmounting it yourself before trying to delete it, run:

fusermount -u <path to secret/>

Migrate an existing secrets directory to be encrypted

EncFS can only mount empty directories but don't worry. Just move the files inside of secret/ to somewhere else, then start the steps above.

Why does it ask for the GPG password twice?

Two files are being encrypted. The EncFS configuration and the EncFS keyfile. If you use an agent then you won't have to enter your password.

What if GPG fails to decrypt?

If the configuration is not decrypted properly, EncFS discards the garbled data and tries to create a new encrypted directory. You can just CTRL+C to quit and fix your issues.

What if you want to keep your encrypted secrets in a git repository?

DebOps by default creates an entry in .gitignore file to prevent committing encrypted files to the git repository. If you are sure that you want to do it, just comment or remove the .encfs.secret line from .gitignore.

You can also use debops.secret role to keep the content of the secret/ directory in other sorts of storage - for details please consult the documentation of that role.
