An example system may be configured to instantiate a first application container based on a plurality of application image layers; and instantiate a second application container based, at least in part, on the plurality of application image layers; wherein a private page cache stores storage information for the plurality of application image layers and is used to provide shared access to the plurality of application image layers by the first application container and the second application container.

Private page cache-based sharing of access to application image layers by application containers

A custom file system in a containerized software architecture facilitates the instantiation of application containers. Each container is composed of one or more application image layers. An application container instance includes read-only application image layer data shared among application container instances associated with the same application container. An application container instance may also include read/write application container instance data that is specific to the application container instance.

Containerized application system graph driver

Techniques and mechanisms described herein provide for a custom file system in a containerized application system in which an application instance may be created as a container based on an application image, which itself may be composed of some number of application image layers. By being aware of these application image layers, the file system can perform image layer level operations such as image layer multisourcing and image layer garbage collection.

Graph driver layer management

Techniques and mechanisms described herein provide for a custom file system in a containerized application system in which an application instance may be created as a container based on an application image, which itself may be composed of some number of application image layers. By being aware of these application image layers, the graph driver can perform image layer level operations such as selectively updating image layers, storing image layers in a way that reflects class of service objectives, and responding to application level queries.
