podman run creates and starts a new container from an image. It can pull the image from a container registry into local container storage, then execute the image's default command or a supplied command. section 2.1 section 2.1.1
Open an interactive shell
podman run -ti --rm registry.access.redhat.com/ubi8/httpd-24 bash connects the terminal to Bash inside a newly pulled container. The container stops when Bash exits, and --rm deletes it afterward. The shell can reveal a different operating-system release, filesystem contents, and process list from the host. section 2.1.1
Launch a web application
podman run -d -p 8080:8080 --name myapp registry.access.redhat.com/ubi8/httpd-24 runs the Apache-based container in detached mode, names it myapp, and maps its container port to localhost:8080. A second running container needs another name and host port. section 2.1.2
