Password Manager Pro Plugin for Ansible

Ansible is a popular open source orchestration tool provided by Red Hat, which helps organizations automate their configuration management and similar repetitive processes. Ansible users can create instructions for a routine task in the form of a 'playbook' that is basically an automation schedule. Execution of these playbooks more often than not require user credentials and similar sensitive information like privileged passwords, API keys, and access tokens to interface with other systems, applications, and services in the environment. In most DevOps environments, such credentials are stored in plaintext within the playbooks to enable smooth task execution without service delays, which can lead to many security and management issues.

The Password Manager Pro lookup plugin developed for secrets management in Ansible helps improve security in organizations' DevOps pipeline. The plugin once enabled in Ansible, ensures that required credentials are retrieved from Password Manager Pro's vault every time when a play is executed, instead of being embedded in plain text within the written template. Upon secure retrieval, the credentials can then be used for actions such as connecting to a remote server. The plugin also saves the user from the arduous job of having to manually update the password/SSH key in the playbooks every time there's an update. Often, there are instances when a play fails owing to an outdated credential in the template. Now with the credentials stored in Password Manager Pro, they're regularly rotated in the vault and also updated in the respective remote device, which ensures that only the latest passwords or keys are retrieved from the vault while running plays.

Steps to Configure Password Manager Pro Plugin for Ansible

The following are the major two steps involved in getting set up and starting to manage secrets in Ansible with Password Manager Pro.

Step 1: Enabling Ansible integration in Password Manager Pro

Step 2: Activating the plugin in Ansible playbooks

Enabling Ansible integration in Password Manager Pro

  1. Log into Password Manager Pro and navigate to Admin >> Integration >> CI/CD Platform Integration.
  2. Click on the Ansible option.
  3. AUTH Token: Click on 'Generate' to populate an AUTH Token automatically. This will be required later while configuring the plugin in Ansible playbooks. Once set up, all incoming connections from Ansible will be validated by Password Manager Pro using this AUTH token.
  4. Jenkins

  5. Username: Here, enter the username of an active Password Manager Pro user whose account will be used automatically by Ansible to securely retrieve the required passwords from Password Manager Pro's vault.

    Important Note: Ensure that the PMP user account you provide has the minimum required permissions for this workflow i.e. privilege to view/retrieve the passwords of resources to which Ansible has to connect.The passwords of resources owned by and shared to this user are the only credentials that Ansible will have access to in Password Manager Pro.
  6. Click 'Enable'.

Activating the plugin in Ansible playbooks

Basically, the Password Manager Pro plugin is called a 'lookup plugin' in Ansible's terms. As an Ansible user, you'll be able to activate this custom lookup plugin by adding it to the lookup folder within the Ansible's installation directory. Once added, you can configure your playbooks to trigger the plugin whenever the play execution requires a set of credentials and the plugin will in turn connect to Password Manager Pro to retrieve the required password or key.

Given below are detailed steps to achieve credential management workflow in Ansible using Password Manager Pro's lookup plugin.

  1. First, download the lookup plugin here. Extract the plugin Python script(.py) from the zip.
  2. Now go to Ansible's installation directory and trace the following path: ansible/lib/ansible/plugins/lookup.
  3. In the lookup folder, drop the plugin file.
  4. Restart the Ansible service.
  5. Once the service is up again, open a playbook that has embedded credentials and remove the plain text credentials. In their place, add a command to invoke the Password Manager Pro lookup plugin to connect to Password Manager Pro and retrieve those credentials securely from the vault.
  6. The command should also specify the names of the resource and account that the plugin should check out from Password Manager Pro.
  7. The command to invoke the plugin should be configured in the playbook in the following format:
{{ lookup('passwordmanagerpro','RESOURCENAME', 'ACCOUNTNAME')}}

  1. Repeat the above step for every playbook that requires privileged credentials. During this process, ensure that every resource and account names that you specify are added to Password Manager Pro's vault beforehand.
  2. After you've made necessary changes in the required playbooks, configure Password Manager Pro's URL and the AUTH Token generated earlier as environmental variables in Ansible.
    • PMP_URL
    • PMP_AUTHTOKEN
  3. You're now all set up now and ready to begin credential management in Ansible using Password Manager Pro.
