Podman (the POD MANager) is an open-source tool for managing OCI containers and images, volumes, and pods. Unlike Docker, Podman operates without a central daemon process, which reduces attack surface and resource consumption at idle. It is developed by Red Hat under the containers organization and has become the default container runtime on Fedora, RHEL, and CentOS Stream.

Core Capabilities

Podman supports the full container lifecycle: building images via Containerfile or Dockerfile (using Buildah under the hood), pulling and pushing images to registries, creating and running containers, checkpoint/restore via CRIU, and pod management. It uses Netavark for networking, crun or runc as OCI runtimes, and containers/storage for image and container storage.

Rootless Containers

One of Podman’s standout features is first-class rootless container support. Containers run within user namespaces, ensuring they never have more privileges than the user who launched them. This makes Podman significantly more secure for development environments and shared CI/CD systems where root access should be avoided.

Docker Compatibility

Podman provides a Docker-compatible CLI interface — most Docker commands work by simply replacing docker with podman. It also exposes a REST API compatible with the Docker API, enabling existing tooling and scripts to work with minimal changes. The podman-docker package even provides a docker alias.

Pod Support

Podman natively supports pods — groups of containers that share networking, storage, and resource constraints. This concept is borrowed from Kubernetes and enables testing of multi-container application topologies locally. Pods can be exported as Kubernetes YAML and deployed directly to clusters.

Agent Integration

AI agents can use Podman for container lifecycle management, image building, running isolated test environments, and managing development infrastructure. The CLI interface and REST API support scripted automation, making it straightforward to integrate into agent workflows for tasks like spinning up databases, running test suites in containers, or managing development stacks.

Installation

Podman is available via most Linux package managers (apt install podman, dnf install podman), Homebrew on macOS (brew install podman), and via the Podman installer on Windows. Podman Desktop provides a GUI for Mac, Windows, and Linux users.
