Container runtime and alternatives

A container runtime, also known as a container engine, is a software component responsible for running and managing containers on a host system. It is a crucial part of containerization technologies like Docker and Kubernetes. The container runtime provides the necessary infrastructure and functionality to create, deploy, and manage containers efficiently.

Popular container runtimes include Docker’s containerd, runc, and CRI-O. These runtimes interact with the underlying containerization platform or orchestrator, such as Docker Swarm or Kubernetes, to manage containers at scale and provide additional features like load balancing, auto-scaling, and high availability.

Podman is an open-source container runtime and toolset that allows users to manage containers and container images. It is an alternative to Docker, offering a compatible interface while operating with a different architecture. Podman is primarily focused on providing a daemonless container runtime, which means it does not require a separate background service or daemon to run containers.
