In Podman 1.0, Red Hat has integrated multiple core security capabilities in an effort to help enable organizations run containers securely. Among the security features are rootless containers and enhanced user namespace support for better container isolation. Containers provide a way for organizations to run applications in a virtualized approach on top of an existing operating system. With the 1.0 release, Red Hat is now also positioning Podman as an alternative to the Docker Engine technology for application container deployment.
