Upgrading to Mitaka from Liberty

Note

This is a WIP - it will be updated as more items are added to Mitaka

Pools Configuration

We have updated how the config data for pools is now stored.

Previously there was a mix of content in the designate.conf file and in the designate database.

We have moved all of the data to the database in Mitaka, to avoid confusion, and avoid the massive complexity that exists in the config file.

Warning

This part of the upgrade requires downtime.

We have 2 new commands in the designate-manage utility that are able to assist the migration.

To make the config syntax simpler we have a new YAML based config file that is used to load information into the database.

../../../etc/designate/pools.yaml.sample

We have a command that will allow you to take your current running config, and export it to the new YAML format.

Note

You will need to have at least one instance of central running, and machine designate-manage is running on will need access to the messageing queue

designate-manage pool generate_file --file output.yml

This will create a YAML file, with all the currently defined pools, and all of their config.

We suggest this is then migrated into a config management system, or other document management system.

From this point on all updated to pools should be one by updating this file, and running:

designate-manage pool update --file /path/to/file.yml

Run

designate-manage pool export_from_config --file output.yml

Run

designate-manage pool update --file output.yml --dry_run True --delete True

Run

designate-manage pool generate_file --file output.yml --delete True
