Operators

To learn how to deploy and configure OpenStack Freezer, consult the documentation available online at:

• OpenStack Freezer <https://docs.openstack.org/freezer/latest/>__

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

• Bug Tracker <https://storyboard.openstack.org/#!/project/openstack/freezer>__

Troubleshooting

When errors occure, these are good places to check:

• freezer-api log: $HOME/log/freezer-api.log /var/log/apache2/freezer-api.log
• freezer-agent log: $HOME/.freezer/freezer.log
• freezer-scheduler log:/var/log/freezer/scheduler.log

Developers

Any new code must follow the development guidelines detailed in the HACKING.rst file and OpenStack general development guidelines, and pass all unit tests.

Further developer focused documentation is available at:

• Official Freezer Documentation <https://docs.openstack.org/freezer/latest/>__
