You can use this role to select a different version of APT packages available without specifying the version directly in the playbooks or roles. This helps to ensure that the APT dependency tree is stable and there are no conflicts between different versions.
debops.apt_preferences role is included in the
common.yml playbook, you
can add your own entries to Ansible’s inventory and they should be picked up
automatically on the next playbook run.
Here’s an example playbook that can be used to manage APT preferences. Debian
Wheezy systems will be configured to prefer
nginx packages from
the Wheezy Backports repository:
--- - hosts: debops_apt_preferences become: True roles: - role: debops.apt_preferences apt_preferences_dependent_list: - package: 'nginx nginx-*' backports: [ 'wheezy' ] reason: 'Support for SPDY protocol'
