Learn to manage Podman networks using key commands: Podman network list, create, inspect, rm, and prune, with a practical demonstration of these operations.

Log in as root and demonstrate Podman networking, including the default bridge, subnet 10.88.0.0/16, and creating a user-defined network to enable container communication and DNS resolution.

Compare rootless and rootful Podman networking, highlighting slirp user-mode networking versus bridge networks. See how IP allocation, DNS, and container communication emerge in a custom network like Think Next Net.

Master the fundamentals of networking in Podman, learn essential commands for managing networks, and see demonstrations for both restful and rootless containers.

Explore how volumes persist data and how to manage and mount them using the Podman CLI, with hands-on examples to solidify understanding.

Explore data storage in Podman containers, noting that containers are ephemeral and rely on a writable layer versus independent named volumes and bind mounts for persistence.

Explore how podman volumes persist data beyond container lifecycles, covering named volumes, bind mounts, and anonymous volumes, and learn mounting with --mount and default host paths like /var/lib/containers/storage/volumes.

Explore common Podman volume commands, including create, list, inspect, and rm, and learn mount options like -v and --mount for named, bind, and anonymous volumes.
