Podman or Pod Manager is a very popular utility for managing containers and the storage volumes that are mounted onto those containers.
A pod is basically a group of different containers. The name of this tool also indicates that it is solely dedicated to container management.
Here at LinuxAPT, as part of our Server Management Services, we regularly help our Customers to perform Software Installation tasks on Ubuntu Linux Systems.

However, this command will also not display any output upon successful execution.

This new container technology improves on Docker by decentralizing the components necessary for container management.
Instead of having a single daemon for everything, Podman uses individualized components that are only used when necessary.
Another advantage of Podman is that it can work with pods, in similar fashion to Kubernetes.

$ sudo apt-get install podman -yWhen the installation completes, verify the installation with the command:
