Create Images on The Fly

Requirements

Have at least one image locally (run podman image ls to confirm).
If you don't have images locally, run simply podman pull nginx:alpine.

Objectives

Run a container using a web server image (e.g. httpd, nginx, ...)

Bind container's port 80 to local port 80
Run it in detached mode
Name should nginx_container

Verify the web server runs and accessible
Create an HTML file with the following content and copy it to the container to the container to path where it will be accessed as an index file

<html>
<head>
<title>It's a me</title>
</head>
<body>
<h1>Mario</h1>
</body>

Create an image out of the running container and call it "nginx_mario"
Tag the container with "mario" tag
Remove the original container (container_nginx) and verify it was removed
Create a new container out of the image you've created (the same way as the original container)
Run curl 127.0.0.1:80. What do you see?
Run podman diff on the new image. Explain the output
