Benefits of Managing Docker with Kubernetes

Docker is a virtualization software tool that allows applications to be deployed under a container. It provides a container management interface software and has an automated mechanism for managing containers. However, Docker mainly solves the problem of operating system layer virtualization on single hosts, but is not as equipped to deal with the needs of a cluster environment with a large number of host nodes. Container deployment scheduling, balancing workload, network node design, high reliability, resource monitoring, management interface, etc., are all problems that Docker does not have the flexibility to deal with. However, the emergence of Kubernetes has solved the aforementioned problems.

Kubernetes (or K8s for short) is a high-margin open source software system for managing containerized work or services, which was released by Google in 2014. Docker and Kubernetes operate at different levels, Docker provides the container wrapper for the application, whereas Kubernetes controls the Docker containers. Through Kubernetes, Docker’s application can be used to allocate containers to appropriate nodes based on resources or rule, and copy and load balancing mechanisms can be set to improve application scalability and reliability. In addition, Kubernetes has a wide selection of support for storage and networking to meet most container application needs.

Finally, Kubernetes has a large community that participates in development and support, providing continuous updates and new features. Using Kubernetes to manage Docker containers is the way most businesses and organization do work today. Kubernetes improves the usability and manageability of Docker containers and is a highly reliable container and management system.
