Abstract
A shim layer can be incorporated into a container image for intercepting calls between an upper layer and a lower layer of the container image according to some aspects described herein. For example, a system can build an image file that includes a stacked arrangement of layers configured for deploying a software program within a container. The stacked arrangement of layers can include a lower layer including one or more objects. The stacked arrangement of layers can include an upper layer positioned above the lower layer, where the upper layer includes the software program. And the stacked arrangement of layers can include a shim layer positioned between the lower layer and the upper layer. The shim layer can include a shim, which is configured to intercept calls involving the one or more objects from the software program and responsively allow or reject the calls based on control data.
