As data center infrastructures continue to grow in scale and complexity, so too must the tools used to manage them. Traditional configuration management tools are no longer adequate for managing today’s distributed systems. Instead, operators are turning to Kubernetes operators to automate the deployment and management of their applications.
Kubernetes operators are software tools that extend the Kubernetes API to provide declarative management of Kubernetes resources. Operators use custom resource definitions (CRDs) to manage applications and their associated resources. CRDs allow operators to define the desired state of an application and its resources, and Kubernetes will ensure that the application always matches that desired state.
Operators can also use Kubernetes labels and annotations to automate the management of an application’s resources. For example, an operator can use labels to automatically provision and configure new resources when they are added to an application.
Kubernetes operators are an ideal tool for managing distributed applications because they provide a declarative management API that can be used to automate the deployment and management of complex applications. In addition, operators can use Kubernetes labels and annotations to further automate the management of an application’s resources.
