The command "podman image history ${image}" is used to display the history of changes made to a container image. Here's an explanation of the different components of the command:

• "podman": This is the command-line tool for working with containers. It is similar to Docker but is designed to be more secure and lightweight.
• "image": This is a subcommand of "podman" used to manage container images, including pulling, pushing, and inspecting them.
• "history": This is an option of the "image" subcommand that specifies to display the history of the container image.
• "${image}": This is a placeholder that represents the name or ID of the container image you want to view the history for.

When you run the command with the specific image name or ID, Podman will retrieve and display a detailed list of changes or layers that were applied to the image during its creation or modification process. The history includes information like the command executed, the size of each layer, and the time it was created or modified. This information is useful for understanding the changes made to an image and for troubleshooting or debugging purposes.
