Understanding Docker and Kubernetes for Document Engine

PSPDFKit Server has been deprecated and replaced by Document Engine. To migrate to Document Engine and unlock advanced document processing capabilities, refer to our migration guide. Learn more about these enhancements on our blog.

Docker is a containerization platform, and Kubernetes is a container orchestrator for container platforms like Docker.

PSPDFKit Server uses the Docker container format. Docker is the most common way to run Docker containers, but there are other technologies to run Docker containers.

Kubernetes is a container orchestrator for container platforms like Docker. It can be used for systems with higher load, where one Docker container isn’t enough. PSPDFKit Server supports horizontal scaling with running multiple containers of itself. The number of nodes that you can run at the same time are defined in the license agreement. Kubernetes is the most popular orchestrator; however, there are alternatives, such as Docker Swarm.
