It also includes corresponding configuration parameters (such as anonymous volumes, environment variables, and users) required within a container runtime. An image does not contain any dynamic data, and its content remains unchanged after being built.</li><li id="cce_bestpractice_0009__li188759145210">Container: Images become containers at runtime, that is, containers are created from images. A container can be created, started, stopped, deleted, or suspended.</li></ul>
