Introducing Kubernetes Operators
We’ve explored the differences between Deployments and StatefulSets, with StatefulSets managing stateful applications that require persistent data storage. We also learned about the manual (and automated) operations needed for StatefulSets to function, such as data synchronization between Pod replicas and initialization tasks.
However, manual intervention goes against the core principles of Kubernetes, where automation and self-healing are paramount. This is where Kubernetes Operators step in.
From humans to software
Imagine replacing human Operators with software Operators. Kubernetes Operators are essentially software extensions that automate complex application management tasks, especially for stateful applications. Instead of relying on manual intervention to maintain application stacks, Operators leverage their built-in software components and intelligence to execute and manage these tasks effectively.
