Securing a Playbook with Ansible Vault

Information is power, and keeping power in the proper hands is important for every system administrator. One method of doing it is by encrypting files that have sensitive information, like passwords, in them. This is especially important when doing something like using `git` to keep playbooks managed. This lab will help practice doing this and working with Ansible. *This course is not approved or sponsored by Red Hat.*

  1. Challenge

    Write the Playbook to be Encrypted

    Note: Please wait an extra minute after the lab starts to make sure all the resources for the lab are ready.

    Our playbook, dba-pass.yml, should look similar to this once we're done editing it:

    - name: Deploy DBA password file
      hosts: dbservers
      become: yes
       - name: Create and pgapass file
          line: 'LinuxAcad'
          create: yes
          owner: dba
          group: dba
          mode: 0600
          path: /home/dba/.pgpass
  2. Challenge

    Encrypt the Playbook

    To encrypt the playbook, we'l run this:

    ansible-vault encrypt dba-pass.yml

    Give a password, then confirm that password, and do not forget that password.

    Now if we try to read that file (cat dba-pass.yml) we'll get a bunch of useless numbers across the screen.

  3. Challenge

    Run the Encrypted Playbook

    To run this encrypted playbook, we'll use this command:

    ansible-playbook --ask-vault-pass dba-pass.yml

    Once we supply the vault password, Ansible will run the playbook just like it would any other.
