Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere.
podman is a daemonless container runtime for managing containers, pods, and container images. It is intended as a counterpart to CRI-O, to provide low-level debugging not available through the CRI interface used by Kubernetes.
CRI-O is an implementation of the Kubernetes CRI (Container Runtime Interface) to enable using OCI (Open Container Initiative) compatible runtimes. It is a lightweight alternative to using Docker as the runtime for kubernetes.
Packer is an open source tool for creating identical machine images for multiple platforms from a single source configuration. Packer is lightweight, runs on every major operating system, and is highly performant, creating machine images for multiple platforms in parallel.
Singularity is a container solution with a focus on building reproducible software stacks and running them most efficiently on existing HPC, scientific, compute farm and even enterprise architectures.
