Can it be said that Kubernetes is used in the current project and who exactly manages it?

To understand whether Kubernetes is used in the project and who manages it, you should:

• Check the project or infrastructure documentation — it usually indicates what technologies are used.
• Ask the DevOps team or system administrators, as they are typically responsible for managing Kubernetes.
• Look at configuration files and deployment scripts — if there are Kubernetes manifests (.yaml files describing Pods, Deployments, etc.), then Kubernetes is used.

Management of Kubernetes is usually handled by DevOps engineers or dedicated cluster administrators, who monitor its status, updates, and scaling. In some teams, developers may have limited access for deploying applications via Kubernetes.
