Abstract
Methods and systems for creating containers by composition are disclosed. For example, a container image includes multiple layers, including first and second layers, which an image engine determines are read only or unmodified by adding any other layers. Each layer is in either a broken or unbroken state. Layers remain unbroken if an associated identifying signature and contents of layer remain unmodified by any other layer. The layers adhere to a policy requiring each compliant layer to be read only and/or not to modify any other layer when added to container image. The policy requires compliant layers to only modify their own contents when updated and to remain unbroken. The first and second layers are compliant when a third layer replaces the first layer. The layers remain compliant after replacement.
