Docker and Kubernetes are two distinct technologies that are often used together in the world of containerization.
1. Docker: Docker is an open-source platform that automates the deployment, scaling, and management of applications. It does this by encapsulating applications into containers, which are independent units containing everything needed to run an application (the code, a run-time environment, libraries, environment variables, and config files). Docker is typically used for managing individual containers, especially on a single node.
1. Kubernetes: While Docker is focused on the individual containers, Kubernetes is designed to manage clusters of nodes, or machines, each running multiple containers. Kubernetes can be viewed as a container platform, a microservices platform, a portable cloud platform and a lot more. It provides a comprehensive framework for running distributed systems resiliently. It’s used for tasks like load balancing, network traffic distribution, scaling, and orchestration of containers, and it works with a range of container tools, including Docker.
In summary, while Docker is particularly efficient in the creation and management of containers, Kubernetes is necessary when you need to orchestrate and schedule those containers in a production environment.
