Podman
Podman is an open-source container engine for developing, managing, and running containers and pods on Linux systems. It provides a daemonless, rootless architecture that allows users to run containers without requiring a background daemon, enhancing security and simplicity. It is designed as a drop-in replacement for Docker, using the same command-line interface and container images.
Developers should learn Podman when working in environments where security and daemonless operation are priorities, such as in CI/CD pipelines, Kubernetes clusters, or development setups on Linux. It is particularly useful for running containers without root privileges, reducing attack surfaces, and integrating with systemd for better process management. Use cases include local development, testing containerized applications, and deploying to production in container orchestration systems.
