Docker and Kubernetes are two different technologies that are often used together in the context of containerized application deployment and management.
Here are the main differences between them
- Docker is a containerization technology that allows developers to package an application and its dependencies into a single, portable unit called a container. Kubernetes is a container orchestration platform that allows developers to deploy and manage containers across a cluster of machines.
- Docker provides an isolated environment for running applications, while Kubernetes provides a platform for managing and scaling containerized applications in a cluster.
- Docker allows developers to build and package containers, while Kubernetes provides a framework for deploying, scaling, and managing those containers.
- Docker provides a simple way to create and manage containers, while Kubernetes provides a more sophisticated set of features for deploying and managing containers at scale, such as automatic scaling, rolling updates, and self-healing.
- Docker can be used on its own to run a single container, while Kubernetes is designed to manage multiple containers running in a cluster.
- Docker is primarily focused on packaging and distribution of containerized applications, while Kubernetes is focused on deployment, scaling, and management of those applications.
Overall, Docker and Kubernetes are complementary technologies that can be used together to create a complete containerization solution for modern application development and deployment.
