Description: Image layers are fundamental components in container architecture, such as Docker and other containerization technologies. Each container image is built from a series of layers stacked on top of each other. These layers represent incremental changes in the file system, where each layer can contain files, configurations, and dependencies necessary to run an application. The main advantage of this approach is efficiency in storage and distribution, as common layers between different images are not duplicated, saving disk space. Additionally, layers allow for rapid creation and deployment of containers, as only layers not present on the local system need to be downloaded. This layered model also facilitates version management, enabling developers to make changes and updates in a more controlled and straightforward manner. In summary, image layers are essential for modularity and efficiency in container usage, providing a solid foundation for the development and deployment of applications in virtualized environments.
