Introduction
- Name: td-redis-operator
- Language: pure go development
- Positioning: Completely based on cloud native technology to realize resource lifecycle management, fault self-healing, HA, etc.
Principle description:
- Based on Operator open source products, it is completely operated and maintained on Kubernate.
- Support two kinds of Redis instance management delivery, namely Redis active and standby and RedisCluster.
- Redis instance resource lifecycle management
Management, operation and maintenance of different modes of redis, adding, deleting and modifying the entire online and offline process. - Operator realizes fault self-healing
Use Operator's informer and reconcile mechanism to code DBA daily operation and maintenance operations, realize self-healing of faults on the cloud, and reduce DBA mental costs. - Cloud native concept
Based on K8S and container technology, the entire fully managed and run on the Kubernate cluster without the need for more infrastructure dependencies, reducing usage costs.
illustrate:
- CRD (Customer Resource Defination) defines a complete attribute to complete the Redis Cluster/Standby resource object. All operation and maintenance operations need to be based on the modification of the CR object.
- Trigger the operation and maintenance code logic and reconcile by tracking the change event of CR to make the resource state converge to the expected state continuously.
