What does Kubernetes need to run in production?

What are the drawbacks of Kubernetes?

  • Here, are cons/ drawbacks of using Kubernetes container: Migrating to stateless requires many efforts Limited functionality according to the availability in the Docker API. Highly complex Installation/configuration process Not compatible existing Docker CLI and Compose tools Complicated manual cluster deployment and automatic horizontal scaling set up
