Container layer

A container layer is a component of a container. Containers are made of many layers; some are immutable and some are open to change. Layers enable applications to reuse functions to save disk space. Container image layers are ready-only, meaning they are immutable and cannot be changed. A container layer is outside of these layers a, meaning that it can be edited.
