    1. By default, Ansible 1.3 and later will try to use native OpenSSH for remote communication when possible. This enables ControlPersist (a performance feature), Kerberos, and options in ~/.ssh/config such as Jump Host setup. However, when using Enterprise Linux 6 operating systems as the control machine (Red Hat Enterprise Linux and derivatives such as CentOS), the version of OpenSSH may be too old to support ControlPersist. On these operating systems, Ansible will fallback into using a high-quality Python implementation of OpenSSH called ‘paramiko’. If you wish to use features like Kerberized SSH and more, consider using Fedora, OS X, or Ubuntu as your control machine until a newer version of OpenSSH is available for your platform – or engage ‘accelerated mode’ in Ansible

    1. You can also set ANSIBLE_VAULT_PASSWORD_FILE environment variable, e.g. ANSIBLE_VAULT_PASSWORD_FILE=~/.vault_pass.txt and Ansible will automatically search for the password in that file.

      Using the ANSIBLE_VAULT_PASSWORD_FILE environment variable is in my mind the most convenient way to configure the secret for ansible-vault.
