Docker and Kubernetes are two complementary technologies that are often used together in modern software development and deployment.
Docker is a platform for creating and managing containers, which are a lightweight and portable way to package and distribute applications, along with their dependencies and configurations, as a single unit that can run consistently across different environments.
Kubernetes, on the other hand, is a container orchestration platform that automates the deployment, scaling, and management of containerized applications across clusters of hosts. Kubernetes provides a declarative API for managing containers, and it can run on a wide range of platforms, from local development environments to public clouds.
Docker and Kubernetes work together in the following way:
Developers use Docker to create container images that contain their applications and dependencies.
These container images are then pushed to a Docker registry, where they can be easily shared and deployed.
Operators use Kubernetes to deploy and manage these container images on a cluster of hosts, using Kubernetes’ declarative API and its built-in features for scaling, load balancing, and self-healing.
Kubernetes can also manage the configuration, secrets, and networking of the containers, as well as monitor their health and performance.
In summary, Docker and Kubernetes are two complementary technologies that work together to enable modern software development and deployment. Docker provides a way to create and manage containers, while Kubernetes provides a way to automate the deployment and management of containerized applications across clusters of hosts.
