Container technology has been enabling application development teams to create individual containers to develop, test, and manage different components of an application. Since each container is packed with all dependencies, it gets extremely easy to host or ship this container across environments – without any issues.
Docker and Kubernetes are two such tools that are ruling the container world, but determining which tool to choose for what application can get intimidating.
Docker is a containerization platform that allows for applications to be run within virtual containers, thus simplifying their development and deployment across a broader environment. Since it wraps all the packages and configurations within individual containers, it enables teams to move applications from a local environment to the production environment – without hassle.
Kubernetes is a container orchestration platform that allows for containers to be run across multiple nodes and clusters. Using Kubernetes, teams can automate the deployment, scaling, and management of containerized applications while providing all the APIs needed for applications to be scaled across multiple servers.
Although Docker and Kubernetes are both used synonymously with container technology, both offer different features and are suited for different requirements.
Although there are certain scenarios where Docker and Kubernetes are better and they both have their own advantages and disadvantages, using both together can open doors to additional benefits and opportunities. Since Docker is the foundation on which Kubernetes sits, and with most of Kubernetes documentation written with Docker in mind, together they can provide a well-integrated, comprehensive platform for container deployment, orchestration, and management at scale.
