Questions tagged [podman]

Podman is a daemon-less container engine for developing, managing, and running OCI Containers on your Linux System. Containers can either be run as root or in rootless mode.

Library and tool for running OCI-based containers in Pods

Libpod provides a library for applications looking to use the Container Pod concept, popularized by Kubernetes. Libpod also contains the Pod Manager tool (Podman). Podman manages pods, containers, container images, and container volumes.

Overview and scope

At a high level, the scope of libpod and Podman is the following:

  • Support multiple image formats including the OCI and Docker image formats.
  • Support for multiple means to download images including trust & image verification.
  • Container image management (managing image layers, overlay filesystems, etc).
  • Full management of container lifecycle
  • Support for pods to manage groups of containers together
  • Resource isolation of containers and pods.
  • Support for a Docker-compatible CLI interface through Podman.
  • Integration with CRI-O to share containers and backend code.
