In Podman run, what does the -p hostPort:containerPort mapping accomplish?

Explanation:
Port mapping with -p hostPort:containerPort means the host port is the entry point, and traffic is forwarded to the container’s port. So -p 8080:80 makes port 8080 on the host forward to port 80 inside the container. This is why the correct description is: forward host port 8080 to container port 80. When you navigate to http://localhost:8080 on the host, you’re reaching the service listening on port 80 inside the container.
