Docker is the most popular utility for packaging and running containers. Docker helps build standard containers that include all the necessary components including code, and libraries. Basically, Docker is more of a container management tool than a container format.
Kubernetes is an open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large and rapidly growing ecosystem.
What’s The Difference?
Both Docker and Kubernetes are production-grade container orchestration platforms, although they have different strengths. The difference between the two is that Kubernetes is meant to run them across a cluster and Docker is about packaging containerized applications on a single node. Since these packages accomplish different things, they are often used in tandem.
