The difference between the two is that Docker is about packaging containerized applications on a single node and Kubernetes is meant to run them across a cluster. Since these packages accomplish different things, they are often used in tandem. Of course, Docker and Kubernetes can be used independently.
Which is better Kubernetes or Docker?
Although Docker Swarm is an alternative in this domain, Kubernetes is the best choice when it comes to orchestrating large distributed applications with hundreds of connected microservices including databases, secrets and external dependencies.
The Kubernetes server runs within a Docker container on your local system, and is only for local testing. Enabling Kubernetes allows you to deploy your workloads in parallel, on Kubernetes, Swarm, and as standalone containers. Enabling or disabling the Kubernetes server does not affect your other workloads.
