I’ve just been setting up Ansible and needed to find a download of the Percona RPM GPG APT-KEY so that I could use the apt_key module. You can download the Percona apt-key here: http://www.percona.com/redir/downloads/RPM-GPG-KEY-percona
With Ansible you can add this key to a server via the play:
tasks:
- name: Add Percona apt-key
action: apt_key url=http://www.percona.com/redir/downloads/RPM-GPG-KEY-percona state=present
