containers/podman

Podman is a tool for managing containers and container images on Linux, macOS, and Windows. Containers are lightweight, isolated environments that package an application and everything it needs to run, so that it behaves consistently regardless of what machine it runs on. Podman solves the same problem as Docker but with a key architectural difference: it does not require a background daemon process running as root to manage containers. Because Podman runs without a central daemon, containers can be started and managed by regular users without any special system privileges. This rootless mode means that even if a container were compromised, an attacker would not gain root access to the host system. Podman is also designed to be command-line compatible with Docker, so most Docker commands work with Podman simply by replacing the word docker with podman. Podman supports the OCI container standard, which means it works with the same container images as Docker, pulled from registries like Docker Hub or Quay.io. It handles the full lifecycle of a container: pulling images, building images from Dockerfiles or Containerfiles, running containers, creating pods (groups of containers sharing resources, similar to Kubernetes pods), managing networking, and managing persistent volumes. You would use Podman when you want a Docker-compatible container workflow without the security implications of a root-owned daemon, or when building container-based applications and want a rootless option. It is also useful as a local development tool for Kubernetes workflows. The tech stack is Go, and Podman is part of a broader open-source container tooling ecosystem. A companion application called Podman Desktop provides a graphical interface. The project is licensed under Apache 2.0.
