DO188 Red Hat OpenShift Development I: Podman Basics:Creating Containers with Podman

Objectives
Run a containerized service with Podman.
An Introduction to Podman
Podman is an open source tool that you can use to manage your containers locally. With Podman, you can find, run, build or deploy OCI (Open Container Initiative) containers and container images.
By default, Podman is daemonless. A daemon is a process that is always running and ready for receiving incoming requests. Some other container tools use a daemon to proxy the requests, which brings a single point of failure. In addition, a daemon might require elevated privileges, which is a security concern. Podman interacts directly with containers, images, and registries without a daemon.
Podman comes in the form of a command-line interface (CLI), which is supported for several operating systems. Along with the CLI, Podman provides two additional ways to interact with your containers and automate processes, the RESTful API and a desktop application called Podman Desktop.
