51. Jenkins is one of the most well-known implementations of pipelines for automating the delivery and deployment of code (CI/CD). It allows automatic building, testing, and deploying of projects.

52. Main entities of Kubernetes:

• Pod — the smallest deployable unit, contains one or more containers.
• Deployment — manages the creation and updating of Pods, providing declarative management.
• ReplicaSet — responsible for maintaining a specified number of Pod copies.
• ConfigMap — stores configuration data as key-value pairs.
• Secrets — stores sensitive data (passwords, tokens) in encrypted form.
• Endpoint — an object that links services with Pod IP addresses.

The points "limits" and "Levels" are not main entities of Kubernetes.
