[Enhancement] Implement automatic backup
Description
Automatic backup of zookeeper db is a useful mechanism in demand in many real-world scenarios. It would be great to implement a separate controller responsible for automatic backup by schedule or on-demand backups. As the simplest implementation we can provide backup of ZooKeeper by copying its transaction and snapshot logs. It's a reasonable method, there is a short article regarding backup/restore procedure for zookeeper: Apache ZooKeeper Backup, a Treatise
Importance
Should-have
Location
Zookeeper operator.
Suggestions for an improvement
Separate controller can be added to watch for a new type of resource (zookeeper-backup for example). Controller should take following responsibilities:
- Provide cluster health check and cancel backup operation if required.
- Detect ZK leader pod and prepare/reconfigure CronJob configuration (Backup pod should land on node where leader is elected).
- Schedule CronJob with a backup script.
- Provide mechanism to periodic checks to make sure CronJob configuration is updated and valid (for example in case of new leader election)
Backup script should contains following steps:
- May contain some additional checks (for example check that it really landed on pod with leader, check datadir folder exists, check free storage space, etc.)
- Create archive of datadir folder and put it in a backup folder (It should be a volume intended for storage backups)
- Check amount of backups and delete oldest if necessary (should be specified in zookeeper-backup cr)
CreateVehicle now use a array instead of vec3 for coords
It should accept an array, map, or vector.
It should accept an array, map, or vector.
Then it's a problem, when i log coord it return a buffer and vehicle spawn at 0, 0, 0
