Podman 4 is a significant upgrade to the daemon-less container engine designed for developing, managing, and running OCI containers on Linux systems, offering enhanced security features by allowing containers to run in rootless mode. This version replaces the CNI networking stack with a new dedicated network stack, featuring Netavark and Aardvark-DNS, tailored to Podman's needs and optimized for single-node container management. The article provides detailed instructions for installing Podman 4 on Arch Linux, including necessary components like netavark, aardvark-dns, and fuse-overlayfs, and describes configurations for rootless operation. It also discusses Podman's authentication compatibility with Docker, the use of Docker Compose and Podman Compose for service orchestration, and the integration of Podman with the build automation tool Earthly, emphasizing its utility as a robust alternative to Docker for container management. Despite some remaining challenges, the release positions Podman as a viable choice for those seeking a Docker substitute with improved security and functionality.
