Ansible Vault Directory Encryption Made Simple

Did you know that while Ansible Vault can encrypt individual files, encrypting entire directories requires a bit more effort?

Ansible Vault Directory Encryption Made Simple

Here’s a simple guide to achieving this:

  1. Encrypting Files Within a Directory

    Ansible Vault specializes in encrypting individual YAML, JSON, and other data files. So, encrypt all files within a directory one by one, use this command:

    ansible-vault encrypt /path/to/directory/*.yml

    This will encrypt all `.yml` files in the directory. For other file types, replace `*.yml` with the appropriate wildcard, such as `*.json`.

  2. Automating Encryption with a Script

    For directories with many files, write a script to automate the encryption process to save time. Here’s a basic script example:

    #!/bin/bash
    for file in /path/to/directory/*; do
    ansible-vault encrypt "$file"
    done

    Here, the script loops through each file in the directory and encrypts it using Ansible Vault.

  3. Alternative Encryption Tools

    Ansible Vault is ideal for encrypting Ansible-related files. For general directory encryption, there are tools like `gpg` or `tar` with encryption options:

    • Using gpg:
      gpg -c /path/to/directory/*

    • Using tar with encryption:
      tar -czvf - /path/to/directory | gpg -c > directory.tar.gz.gpg

Detailed Steps for Directory Encryption with Ansible Vault

  1. To begin with, make sure Ansible is installed on the system. We can install it via package managers like `apt`, `yum`, or `pip`:

    # For Ubuntu/Debian
    sudo apt update
    sudo apt install ansible
    # For CentOS/RHEL
    sudo yum install ansible
    # Using pip
    pip install ansible

  2. Then, create a new Ansible Vault file where we will store the encrypted data:

    ansible-vault create vault_file.yml

    Now, we will be prompted to set a password for this vault file. Remember this password, as it’s needed for both encryption and decryption.

  3. Next, encrypt all files in a directory recursively using:

    ansible-vault encrypt /path/to/directory/*

    Remember to replace `/path/to/directory` with the path of the directory we want to encrypt. So, each file in the directory will be encrypted individually.

  4. When running the `ansible-vault encrypt` command, we have to enter the vault password we set earlier. This password helps encrypt the files.
  5. Then, check the files are encrypted by opening them. Encrypted files will contain a block of unreadable, encrypted data.

Also, we can easily decrypt the directory contents temporarily with:

ansible-vault decrypt /path/to/directory/*

Then, enter the vault password to decrypt the files. After making any changes, remember to re-encrypt them using the `ansible-vault encrypt` command.

While Ansible Vault doesn’t directly encrypt entire directories, these workarounds and additional tools help achieve similar results.
