What is this?
If you use Ansible Vault
then you may have encountered the problem of needing to roll your vault password. Maybe
you found it written down on a sticky note, maybe a coworker who knows it left the
company, maybe you accidentally typed it into Slack when you thought the focus was on your
terminal. Whatever, these things happen.
The built-in tool Ansible provides,
ansible-vault rekey,
suffers from two main drawbacks: first, it only works on vault encrypted files and not on
vault encrypted YAML data; and second, it only works on a single vault encrypted file at a
time. To rekey everything in a large project you'd need to write a script that recursively
goes through every file and rekeys every encrypted file and YAML variable all at once.
This is that script.
Installing
If you're using Poetry or
Pipenv to manage your Ansible runtime environment,
you can just add vault2vault to that same environment:
# using poetry
poetry add vault2vault --dev

# using pipenv
pipenv install vault2vault

If you're using Ansible from your system package manager, it's probably easier to just
install vault2vault using PipX and the ansible extra:
pipx install vault2vault[ansible]

Note: vault2vault requires an Ansible installation to function. If you are installing to
a standalone virtual environment (like with PipX) then you must install it with the
ansible extra to ensure a version of Ansible is available to the application.**

Usage

Note: the full command reference is available by running vault2vault --help

Vault2Vault works with files in any arbitrary directory structures, so there is no need to
have your Ansible project(s) structured in a specific way for the tool to work. The
simplest usage of Vault2Vault is by passing the path to your Ansible project directory to
the command:
vault2vault ./my-ansible-project/

The tool will prompt for the current vault password and the new vault password and then
process every file under the provided path. You can also specify multiple paths and
they'll all be processed together:
vault2vault \
./my-ansible-project/playbooks/ \
./my-ansible-project/host_vars/ \
./my-ansible-project/group_vars/

To skip the interactive password prompts you can put the password in a file and have the
tool read it in at runtime. The --old-pass-file and --new-pass-file parameters work
the same way as the --vault-password-file option from the ansible command:
vault2vault ./my-ansible-project/ \
--old-pass-file=./oldpass.txt \
--new-pass-file=./newpass.txt

If you use multiple vault passwords in your project and want to roll them you'll need to
run vault2vault once for each password you want to change. By default, vault2vault
will fail with an error if it encounters vaulted data that it cannot decrypt with the
provided current vault password. To change this behavior and instead just ignore any
vaulted data that can't be decrypted (like, for example, if you have data encrypted with
multiple vault passwords) you can pass the --ignore-undecryptable flag to turn the
errors into warnings.

Please report any bugs or issues you encounter on
Github.

Recovering from a failed migration
This tool is still pretty early in it's development, and to be honest it hooks into
Ansible's functionality in some fragile ways. I've tested as best I can to ensure it
covers as many edge cases as possible, but there is still the chance that you might get
partway through a password migration and then have the tool fail out, leaving half of your
data successfully rekeyed and the other half not.
In the spirit of the
Unix philosophy
this tool does not include any built-in way to recover from this state. However, it can be
done very effectively using a version control tool.
If you are using Git to track your project files then you can use the command
git reset --hard to restore all files to the state of the currently checked out commit.
This does have the side effect of erasing any other un-committed work in the repository,
so it's recommended to always have a clean working tree when using Vault2Vault.
If you are not using a version control system to track your project files then you can
create a temporary Git repository to use in the event of a migration failure:
cd my-project/

# Initialize the new repository
git init

# Add and commit all your existing files to the git tree
git add .
git commit -m "initial commit"

# Run vault migrations
vault2vault ...

# If no recovery is necessary, delete the git repository data
rm -rf .git

Roadmap
This project is considered feature complete as of the
0.1.1 release. As a result the
roadmap focuses on stability and user experience ahead of a 1.0 release.

Reimplement core vaulted data processing function to enable multithreading
Implement multithreading for performance in large environments
Add unit tests
Add integration tests
Redesign logging messages to improve clarity and consistency
